I need help changing the range and showing the user what the range is so they know if they are closer or not. I have given the description I have been given. On what I need to do . I have given the code that I have come up wit so far. Let me know if you need anything else from me.
Step 6 – Guiding the user with the range of values to select between
Add functionality so that when displaying the guess prompt it will display the current range
to guess between based on the user’s guesses accounting for values that are too high and too
low. It will start out by stating What is your guess between 1 and 100, inclusive?, but as
the user guesses the range will become smaller and smaller based on the value being higher
or lower than what the user guessed, e.g., What is your guess between 15 and 32,
inclusive? The example output below should help clarify.
EXAMPLE
----------------
What is your guess between 1 and 44 inclusive? 2

What you'll need is a place to hold the user's lowest and highest guess. Then you'd use those for the range checks, instead of the hardcoded 1 and 11. With each guess, if it's a valid one, you then would compare it to the lowest and highest values, and if it's lower than the lowest then it sets the lowest value to the guess, and if it's higher than the highest it'll set the highest value to the guess. Lastly you'll need to update the input() string to display the lowest and highest guesses instead of a hardcoded '1' and '10'.
You need to simplify a lot your code. Like there is about 6 different places where you ask a new value, there sould be only one, also don't call method recursivly (call again() in again()) and such call between again>play>again.
Use an outer while loop to run games, and inside it an inner while loop for the game, and most important keep track of lower_bound and upper_bound

I'm having an issue with my program. I'm working on a program that lets you play a small game of guessing the correct number. The problem is if you guess the correct number it will not print out: "You guessed it correctly". The program will not continue and will stay stuck on the correct number. This only happens if you have to guess multiple times. I've tried changing the else to a break command but it didn't work.
Is there anyone with a suggestion?
This is what I use to test it:
smallest number: 1
biggest number: 10
how many times can u guess: 10
If you try to guess the correct number two or three times (maybe more if u need more guesses) it will not print out you won.
import random
#counts the mistakes
count = 1
#askes to give up a minimum and maximum to guess between
minimum = int(input("what is the smallest number? "))
maximum = int(input("what is the biggest number? "))
#askes how many times u can guess in total
amount = int(input("How many times can you guess? "))
#random number between the 2 variables minimum and maximum
x = random.randrange(minimum, maximum)
guess = int(input("guess the number: "))
#while loop until the guess is the same as the random number
while guess != x:
#this is if u guessed to much u get the error that you've guessed to much
while count < amount:
if guess > x:
print("this is not the correct number, the correct number is lower \n")
guess = int(input("guess the number: "))
count += 1
elif guess < x:
print("this is not the correct number, the correct number is higher \n")
guess = int(input("guess the number: "))
count += 1
else: print("\n \nYou Lost, You've guessed", x, "times\n")
break
#this part is not working, only if you guess it at the first time. it should also print this if you guessed it in 3 times
else: print("You guessed it correctly", x)
test = (input("this is just a test if it continues out of the loop "))
print(test)
The main issue is that once guess == x and count < amount you have a while loop running that will never stop, since you don't take new inputs. At that point, you should break out of the loop, which will also conclude the outer loop
You can do it simply by using one while loop as follows:
import random
#counts the mistakes
count = 1
#askes to give up a minimum and maximum to guess between
minimum = int(input("what is the smallest number? "))
maximum = int(input("what is the biggest number? "))
#askes how many times u can guess in total
amount = int(input("How many times can you guess? "))
#random number between the 2 variables minimum and maximum
x = random.randrange(minimum, maximum)
#this is if u guessed too much u get the error that you've guessed too much
while count <= amount:
guess = int(input("guess the number: "))
if guess > x:
print("this is not the correct number, the correct number is lower \n")
count += 1
elif guess < x:
print("this is not the correct number, the correct number is higher \n")
count += 1
else:
print("You guessed it correctly", x)
break
if guess!=x:
print("\n \nYou Lost, You've guessed", count, "times\n")
As Lukas says, you've kind of created a situation where you get into a loop you can never escape because you don't ask again.
One common pattern you could try is to deliberately make a while loop that will run and run, until you explicitly break out of it (either because the player has guessed too many times, or because they guessed correctly). Also, you can get away with only asking for a guess in one part of your code, inside that while loop, rather than in a few places.
Here's my tweak to your code - one of lots of ways of doing what you want to:
import random
#counts the mistakes
count = 0
#asks to give up a minimum and maximum to guess between
minimum = int(input("what is the smallest number? "))
maximum = int(input("what is the biggest number? "))
#asks how many times u can guess in total
amount = int(input("How many times can you guess? "))
#random number between the 2 variables minimum and maximum
x = random.randrange(minimum, maximum)
#while loop until the guess is the same as the random number
while True:
if count < amount:
guess = int(input("guess the number: "))
#this is if u guessed to much u get the error that you've guessed to much
if guess > x:
print("this is not the correct number, the correct number is lower \n")
count += 1
elif guess < x:
print("this is not the correct number, the correct number is higher \n")
count += 1
else:
print("You guessed it correctly", x)
break
else:
print("\n \nYou Lost, You've guessed", x, "times\n")
PS: You got pretty close to making it work, so nice one for getting as far as you did!
This condition is never checked again when the guessed number is correct so the program hangs:
while guess != x:
How about you check for equality as the first condition and break out of the loop if true:
import random
#counts the mistakes
count = 1
#askes to give up a minimum and maximum to guess between
minimum = int(input("what is the smallest number? "))
maximum = int(input("what is the biggest number? "))
#askes how many times u can guess in total
amount = int(input("How many times can you guess? "))
#random number between the 2 variables minimum and maximum
x = random.randrange(minimum, maximum)
guess = int(input("guess the number: "))
if guess == x:
print("You guessed it correctly", x)
else:
while count < amount:
if guess > x:
print("this is not the correct number, the correct number is lower \n")
guess = int(input("guess the number: "))
count += 1
elif guess < x:
print("this is not the correct number, the correct number is higher \n")
guess = int(input("guess the number: "))
count += 1
else:
print("You guessed it correctly", x)
break
else:
print("You guessed too many times")
I've been learning Python for about 4 days and I'm just dealing with my first problem.
import random
number=random.randint(1,10)
count=1
guess= int(input("Enter your guess between 1 and 10 : "))
while number != guess:
count = count + 1
if guess == number:
print("That is my number !")
while guess < number:
guess = int(input("Too low :( Guess again ! : "))
if guess == number:
print("That is my number !")
while guess > number:
guess = int(input("Too high :( Guess again ! : "))
if guess == number:
print("That is my number !")
My program just print only first input line and then nothing.
Enter your guess between 1 and 10 :
Why is that?
while number != guess:
count = count + 1
When I delete this two lines, it works perfectly.
In Python whitspace is significant, because the loop was not indented correctly, the your program did not work as expected. The corrected code looks like this:
import random
number = random.randint(1,10)
count = 1
guess = int(input("Enter your guess between 1 and 10 : "))
while number != guess:
count = count + 1
if guess == number:
print("That is my number !")
elif guess < number:
guess = int(input("Too low :( Guess again ! : "))
else:
guess = int(input("Too high :( Guess again ! : "))
I am struggling with some simple algorithm which should make python guess the given number in as few guesses as possible. It seems to be running but it is extremely slow. What am I doing wrong. I have read several topics already concerning this problem, but can't find a solution. I am a beginner programmer, so any tips are welcome.
min = 1
max = 50
number = int(input(("please choose a number between 1 and 50: ")))
total = 0
guessed = 0
while guessed != 1:
guess = int((min+max)/2)
total += 1
if guess == number:
print("The number has been found in ",total," guesses!")
guessed = 1
elif guess > number:
min = guess + 1
elif guess < number:
max = guess - 1
Thanks
ps. I am aware the program does not check for wrong input ;)
Your logic is backwards. You want to lower the max when you guess too high and raise the min when you guess too low. Try this:
if guess == number:
print("The number has been found in ",total," guesses!")
guessed = 1
elif guess > number:
max = guess - 1
elif guess < number:
min = guess + 1
Apart from having the logic backwards, you should not be using min and max as variable names. They are python functions. You can also use while True and break as soon as the number is guessed.
while True:
guess = (mn + mx) // 2
total += 1
if guess == number:
print("The number has been found in {} guesses!".format(total))
break
elif guess < number:
mn = guess
elif guess > number:
mx = guess
You will also see by not adding or subtracting 1 from guess this will find the number in less steps.
from random import randint
print('choose a number in your brain and if guess is true enter y else any key choose time of guess: ')
print("define the range (A,B) :")
A = int(input("A: "))
B = int(input("B: "))
time = int(input("time:"))
while time != 0:
ran = randint(A, B)
inp = input(f"is this {ran} ?")
time -= 1
if inp == "y":
print("bla bla bla python wins!")
break
print("NOPE!")
if time == 0:
print("computer game over!")
break
I am very new to programming so I decided to start with Python about 4 or 5 days ago. I came across a challenge that asked for me to create a "Guess the number" game. After completion, the "hard challenge" was to create a guess the number game that the user creates the number and the computer (AI) guesses.
So far I have come up with this and it works, but it could be better and I'll explain.
from random import randint
print ("In this program you will enter a number between 1 - 100."
"\nAfter the computer will try to guess your number!")
number = 0
while number < 1 or number >100:
number = int(input("\n\nEnter a number for the computer to guess: "))
if number > 100:
print ("Number must be lower than or equal to 100!")
if number < 1:
print ("Number must be greater than or equal to 1!")
guess = randint(1, 100)
print ("The computer takes a guess...", guess)
while guess != number:
if guess > number:
guess -= 1
guess = randint(1, guess)
else:
guess += 1
guess = randint(guess, 100)
print ("The computer takes a guess...", guess)
print ("The computer guessed", guess, "and it was correct!")
This is what happened on my last run:
Enter a number for the computer to guess: 78
The computer takes a guess... 74
The computer takes a guess... 89
The computer takes a guess... 55
The computer takes a guess... 78
The computer guessed 78 and it was correct!
Notice that it works, however when the computer guessed 74, it then guessed a higher number to 89. The number is too high so the computer guesses a lower number, however the number chosen was 55. Is there a way that I can have the computer guess a number that is lower than 89, but higher than 74? Would this require additional variables or more complex if, elif, else statements?
Thank you Ryan Haining
I used the code from your reply and altered it slightly so the guess is always random. If you see this, let me know if this is the best way to do so.
from random import randint
def computer_guess(num):
low = 1
high = 100
# This will make the computer's first guess random
guess = randint(1,100)
while guess != num:
print("The computer takes a guess...", guess)
if guess > num:
high = guess
elif guess < num:
low = guess + 1
# having the next guess be after the elif statement
# will allow for the random guess to take place
# instead of the first guess being 50 each time
# or whatever the outcome of your low+high division
guess = (low+high)//2
print("The computer guessed", guess, "and it was correct!")
def main():
num = int(input("Enter a number: "))
if num < 1 or num > 100:
print("Must be in range [1, 100]")
else:
computer_guess(num)
if __name__ == '__main__':
main()
what you are looking for is the classic binary search algorithm
def computer_guess(num):
low = 1
high = 100
guess = (low+high)//2
while guess != num:
guess = (low+high)//2
print("The computer takes a guess...", guess)
if guess > num:
high = guess
elif guess < num:
low = guess + 1
print("The computer guessed", guess, "and it was correct!")
def main():
num = int(input("Enter a number: "))
if num < 1 or num > 100:
print("Must be in range [1, 100]")
else:
computer_guess(num)
if __name__ == '__main__':
main()
The algorithm works by selecting a low and high limit to start with (in your case low=1 and high=100). It then checks the midpoint between them.
If the midpoint is less than number, the midpoint becomes the new lower bound. If the midpoint is higher, it becomes the new upper bound. After doing this a new midpoint is generated between the upper and lower bound.
To illustrate an example let's say you're looking for 82.
Here's a sample run
Enter a number: 82
The computer takes a guess... 50
The computer takes a guess... 75
The computer takes a guess... 88
The computer takes a guess... 82
The computer guessed 82 and it was correct!
So what's happening here in each step?
low = 1, high = 100 => guess = 50 50 < 82 so low = 51
low = 51, high = 100 => guess = 75 75 < 82 so low = 76
low = 76, high = 100 => guess = 88 88 > 82 so high = 88
low = 76, high = 88 => guess = 82 82 == 82 and we're done.
Note that the time complexity of this is O(lg(N))
I briefly made the game which you need with follows:
import random
guess=int(input("Choose a number you want the computer to guess from 1-100: "))
turns=0
a=None
compguess=random.randint(1,100)
while turns<10 and 100>guess>=1 and compguess!=guess: #computer has 10 turns to guess number, you can change it to what you want
print("The computer's guess is: ", compguess)
if compguess>guess:
a=compguess
compguess=random.randint(1,compguess)
elif compguess<guess:
compguess=random.randint(compguess,a)
turns+=1
if compguess==guess and turns<10:
print("The computer guessed your number of:" , guess)
turns+=1
elif turns>=10 and compguess!=guess:
print("The computer couldn't guess your number, well done.")
input("")
This is a bit rusty, but you could improve it by actually narrowing down the choices so the computer has a greater chance of guessing the right number. But where would the fun in that be? Notice how in my code, if the computer guesses a number which is greater than than the number the user has inputed, it will replace 100 from the randint function with that number. So if it guesses 70 and its too high, it won't choose a number greater than 70 after that. I hope this helps, just ask if you need any more info. And tell me if it's slightly glitchy
This is how I went about mine...
__author__ = 'Ghengis Yan'
print("\t This is the age of the computer")
print("\n The computer should impress us... the Man")
import random
#User chooses the number
the_number = int(input("Human Choose a number between 0 and 100 "))
tries = 1
computer = random.randint(0,100)
# User choose again loop
while the_number > 100:
the_number = int(input("I thought Humans are smarter than that... \nRetype the number... "))
if the_number <= 100:
print("Good")
# Guessing Loop
while computer != the_number:
if computer > the_number:
print(computer, "lower... Mr. Computer")
else:
print(computer, "higher... Mr. Computer")
computer = int(random.randint(0,100))
tries += 1
print("Computer Congratulations... You beat the human! The Number was ", the_number)
print("It only took a computer such as yourself", tries, "tries to guess it right... pathetic")
input("\nPress the enter key to exit.")
What I did for the same challenge was:
1) Define a variable that records the max value input by guessing computer.
Ex:
max_guess_number = 0
2) Define another variable with the lowest guessed value.
Ex.
min_guess_number = 0
3) Added in the "if computer_guess > secret_number" clause the following code (I added -1 so that the computer wouldn't try to guess the already previously tried number):
max_guess_number = guess - 1
computer_guess = random.randint(min_guess_number, max_guess_number)
4) Added the following code in the "if computer_guess < secret_number":
min_guess_number = guess + 1
computer_guess = random.randint(min_guess_number, max_guess_number)
Worth noting is the fact that I set my while loop to loop until another variable "guess_status" changes into a value 1 (the default I set to 0). This way I actually saw the result when the while loop finished.
print 'Please think of a number between 0 and 100!'
low = 0
high = 100
while(True):
rand = (high+low)/2
print 'Is your secret number '+str(rand)+'?'
ans = raw_input("Enter 'h' to indicate the guess is too high. Enter 'l' to indicate the guess is too low. Enter 'c' to indicate I guessed correctly.")
if ans=='h':
high = rand
elif ans=='l':
low = rand
elif ans=='c':
print "Game over. Your secret number was:",rand
break
else:
print "Sorry, I did not understand your input"
You only need two new variables to keep track of the low and high limits :
low = 1
high = 100
while guess != number:
if guess > number:
high = guess - 1
else:
low = guess + 1
guess = randint(low, high)
print ("The computer takes a guess...", guess)
Try this:
import random
player = int(input("tap any number: "))
comp = random.randint(1, 100)
print(comp)
comp_down = 1
comp_up = 100
raw_input("Press Enter to continue...")
while comp != player:
if comp > player:
comp_up = comp - 1
comp = random.randint(comp_down, comp_up)
print(comp)
if comp < player:
comp_down = comp + 1
comp = random.randint(comp_down, comp_up)
print(comp)
if comp == player:
break
If you use the stuff in the chapter (guessing this is from the Dawson book) you can do it like this.
import random
#program allows computer to guess my number
#initial values
user_input1=int(input("Enter number between 1 and 100: "))
tries=1
compguess=random.randint(1, 100)
#guessing loop
while compguess != user_input1:
if compguess > user_input1:
print("Lower Guess")
compguess=random.randint(1, 100)
print(compguess)
elif compguess < user_input1:
print("Higher Guess")
compguess=random.randint(1, 100)
print(compguess)
tries += 1 #to have program add up amount of tries it takes place it in the while block
print("Good job Computer! You guessed it! The number was,", user_input1, \
" and it only took you", tries, " tries!")
import random
corr_num = random.randint(1,100)
player_tries = 0
com_tries = 0
while player_tries <5 and com_tries < 5:
player = int(input("player guess is "))
if player > corr_num:
print("too high")
player_tries +=1
if player < corr_num:
print("too low")
player_tries +=1
if player == corr_num:
print("Player wins")
break
computer = random.randint(1,100)
print("computer guess is ", computer)
if computer > corr_num:
print("too high")
com_tries = 0
if computer < corr_num:
print("too low")
com_tries = 0
if computer == corr_num:
print ("computer wins")
break
else:
print("Game over, no winner")**strong text**
import random
x = 1

print(hads)

This is the code that I created to simplify the problem you were facing a lot more.
num = int(input("Enter a number between 1 and 100: "))
low = 1
high = 100
guess = (low+high)//2
while guess != num:
guess = (low+high)//2
print("The computer takes a guess...", guess)
if guess > num:
high = guess
else:
low = guess + 1
print("The computer guessed", guess, "and it was correct!")
import random
userNum = int(input("What will the secret number be (1-100)? "))
attempts = 0
guess = 0
lowCap = 1
highCap = 100
while guess != userNum:
guess = random.randint(lowCap,highCap)
if guess > userNum:
highCap = guess
attempts += 1
elif guess < userNum:
lowCap = guess
attempts += 1
print("The computer figured out the secret number in", + attempts, "tries.")
I was doing a similar scenario today for an assignment and only now figured out how to make it easily cut down through the numbers by changing random.randint(1, 100) to random.randint(lowCap, highCap) which will change as the computer keep making guesses.
