Implement the GuessNumber game. In this game, the computer
- Think of a random number in the range 0-50. (Hint: use the random module.)
- Repeatedly prompt the user to guess the mystery number.
- If the guess is correct, congratulate the user for winning. If the guess is incorrect, let the user know if the guess is too high or too low.
- After 5 incorrect guesses, tell the user the right answer.
The following is an example of correct input and output.
I’m thinking of a number in the range 0-50. You have five tries to
guess it.
Guess 1? 32
32 is too high
Guess 2? 18
18 is too low
Guess 3? 24
You are right! I was thinking of 24!
This is what I got so far:
import random
randomNumber = random.randrange(0,50)
print("I’m thinking of a number in the range 0-50. You have five tries to guess it.")
guessed = False
while guessed == False:
userInput = int(input("Guess 1?"))
if userInput == randomNumber:
guessed = True
print("You are right! I was thinking of" + randomNumber + "!")
elif userInput>randomNumber:
print(randomNumber + "is too high.")
elif userInput < randomNumber:
print(randomNumber + "is too low.")
elif userInput > 5:
print("Your guess is incorrect. The right answer is" + randomNumber)
print("End of program")
I've been getting a syntax error and I don't know how to make the guess increase by one when the user inputs the wrong answer like, Guess 1?, Guess 2?, Guess 3?, Guess 4?, Guess 5?, etc...
Since you know how many times you're going through the loop, and want to count them, use a for loop to control that part.
for guess_num in range(1, 6):
userInput = int(input(f"Guess {guess_num} ? "))
if userInput == randomNumber:
# insert "winner" logic here
break
# insert "still didn't guess it" logic here
Do you see how that works?
You forgot to indent the code that belongs in your while loop. Also, you want to keep track of how many times you guessed, with a variable or a loop as suggested. Also, when giving a hint you probably want to print the number guessed by the player, not the actual one. E.g.,
import random
randomNumber = random.randrange(0,50)
print("I’m thinking of a number in the range 0-50. You have five tries to guess it.")
guessed = False
count = 0
while guessed is False and count < 5:
userInput = int(input("Guess 1?"))
count += 1
if userInput == randomNumber:
guessed = True
print("You are right! I was thinking of" + randomNumber + "!")
elif userInput > randomNumber:
print(str(userInput) + " is too high.")
elif userInput < randomNumber:
print(str(userInput) + " is too low.")
if count == 5:
print("Your guess is incorrect. The right answer is" + str(randomNumber))
print("End of program")
You are facing the syntax error because you are attempting to add an integer to a string. This is not possible. To do what you want you need to convert randomNumber in each print statement.
import random
randomNumber = random.randrange(0,50)
print("I’m thinking of a number in the range 0-50. You have five tries to guess it.")
guessed = False
while guessed == False:
userInput = int(input("Guess 1?"))
if userInput == randomNumber:
guessed = True
print("You are right! I was thinking of" + str(randomNumber) + "!")
elif userInput>randomNumber:
print(str(randomNumber) + "is too high.")
elif userInput < randomNumber:
print(str(randomNumber) + "is too low.")
elif userInput > 5:
print("Your guess is incorrect. The right answer is" + randomNumber)
print("End of program")
import random
arr=[]
for i in range(50):
arr.append(i)
answer=random.choice(arr)
for trial in range(5):
guess=int(input("Please enter your guess number between 0-50. You have 5
trials to guess the number."))
if answer is guess:
print("Congratulations....You have guessed right number")
break
elif guess < answer-5:
print("You guessed too low....Try again")
elif guess > answer+5:
print("You guessed too high..Try again")
else:
print("Incorrect guess...Try again please")
print("the answer was: "+str(answer))
Just a three things to add:
The "abstract syntax tree" has a method called literal_eval that is going to do a better job of parsing numbers than int will. It's the safer way to evaluate code than using eval too. Just adopt that method, it's pythonic.
I'm liberally using format strings here, and you may choose to use them. They're fairly new to python; the reason to use them is that python strings are immutable, so doing the "This " + str(some_number) + " way" is not pythonic... I believe that it creates 4 strings in memory, but I'm not 100% on this. At least look into str.format().
The last extra treat in this is conditional assignment. The result = "low" if userInput < randomNumber else "high" line assigns "low" of the condition is met and "high" otherwise. This is only here to show off the power of the format string, but also to help contain conditional branch complexity (win and loss paths are now obvious). Probably not a concern for where you are now. But, another arrow for your quiver.
import random
from ast import literal_eval
randomNumber = random.randrange(0,50)
print("I’m thinking of a number in the range 0-50. You have five tries to guess it.")
win = False
for guess_count in range(1,6):
userInput = literal_eval(input(f"Guess {guess_count}: "))
if userInput == randomNumber:
print(f"You are right! I was thinking of {randomNumber}!")
win = True
break
else:
result = "low" if userInput < randomNumber else "high"
print(f"{userInput} is too {result}")
if win:
print ("YOU WIN!")
else:
print("Better luck next time")
print("End of program")

My son has this project he has to do in python and is stuck.
He needs to make a number guessing game. The code must generate a random secret number between 0 and 10, then give the user 5 attempts to guess that number, each guess if not correct must indicate if it is higher or lower than the secret random number. After each guess the code needs to display text stating what has happened. The code also needs to store all guesses and display them at the end. Needs to be made using loop, if, elif, else and an array or list code.
The attempt so far is below
print("Hi there, lets play a little guessing game. Guess the number between 0 and 10")
from random import randint
x = [randint(0,10)]
counter = 0
guess = input("Enter guess:")
while counter < 5:
print("You have " + str(counter) + " guesses left")
counter = counter +1
if guess == x:
print("Congrats you got it")
break
elif guess > x:
print("Too high")
elif guess < x:
print("Too low")
else:
print("You lost")
break
Any help to correct my sons code would be appreciated as this project is due soon and he cannot access his tutor
This should do it. What the code does is explained in comments below.
You need to do x=randint(0,10) which will assign the random number to a variable, i.e x=4 rather than `x = [randint(0,10)], which assigns the random number to a list ,x=[4]```
Also you need to ask for a guess in the loop, instead of doing it only one before the loop started.
Also you would need to convert the string to an int for comparison i.e. guess = int(input("Enter guess:"))
print("Hi there, lets play a little guessing game. Guess the number between 0 and 10")
#Create a random number
from random import randint
x = randint(0, 10)
counter = 0
won = False
#Run 5 attempts in a loop
while counter<5:
#Get the guess from the user
guess = int(input("Enter guess:"))
counter = counter+1
#Check if the guess is the same, low or high as the random number
if guess == x:
print("Congrats you got it")
won = True
break
elif guess > x:
print("Too high")
elif guess < x:
print("Too low")
print("You have " + str(5 - counter) + " guesses left")
#If you didn't won, you lost
if not won:
print("The number was ", x)
print("You Lost")
So here are the corrections. So x has been initialized as array rather than an integer. So none of the comparisons with guess will be working. Also the counter logic is wrong. Rather than starting from zero, start from 5 which is the maximum number of chances and go from the reverse rather. Then at each if/elif loop append all the guesses and print it in the end.
Here is the corrected code
from random import randint
x = randint(0,10)
print(x)
counter = 5
guesses=[] #initalize an empty list to store all guesses
while counter != 0:
guess = input("Enter guess:")
if guess == x:
print("Congrats you got it")
guesses.append(guess)
break
elif guess > x:
print("Too high")
guesses.append(guess)
elif guess < x:
print("Too low")
guesses.append(guess)
else:
print("You lost")
break
counter = counter-1
print("You have " + str(counter) + " guesses left")
print(guesses)
Edit:
x = [randint(0,10)] wouldn't work as you are creating a list here instead of single guess
print("You have " + str(counter) + " guesses left") is also incorrect. You might instead set counter to 5 and check for counter > 0 and do counter -= 1, that way message can be fixed
Lastly to store all guesses you would need a variable
from random import randint
if __name__ == "__main__":
number_to_guess = randint(0,10)
guesses = []
for c in range(5,0,-1):
guessed = input("Enter guess:")
guessed = guessed.strip()
assert guessed.isnumeric()
guessed = int(guessed)
guesses.append(guessed)
if guessed == number_to_guess:
print("yes")
break
elif guessed > number_to_guess:
print("more")
else:
print("less")
c -= 1
print("pending guesses", c)
print("Expected - ", number_to_guess)
print("All guesses - ", guesses)
For a class assignment, I'm trying to make a number guessing game in which the user decides the answer and the number of guesses and then guesses the number within those limited number of turns. I'm supposed to use a while loop with an and operator, and can't use break. However, my issue is that I'm not sure how to format the program so that when the maximum number of turns is reached the program doesn't print hints (higher/lower), but rather only tells you you've lost/what the answer was. It doesn't work specifically if I choose to make the max number of guesses 1. Instead of just printing " You lose; the number was __", it also prints a hint as well. This is my best attempt that comes close to doing everything that this program is supposed to do. What am I doing wrong?
answer = int(input("What should the answer be? "))
guesses = int(input("How many guesses? "))
guess_count = 0
guess = int(input("Guess a number: "))
guess_count += 1
if answer < guess:
print("The number is lower than that.")
elif answer > guess:
print("The number is higher than that")
while guess != answer and guess_count < guesses:
guess = int(input("Guess a number: "))
guess_count += 1
if answer < guess:
print("The number is lower than that.")
elif answer > guess:
print("The number is higher than that")
if guess_count >= guesses and guess != answer:
print("You lose; the number was " + str(answer) + ".")
if guess == answer:
print("You win!")
What about something like this?
answer = int(input("What should the answer be? "))
guesses = int(input("How many guesses? "))
guess_count = 1
guess_correct = False
while guess_correct is False:
if guess_count < guesses:
guess = int(input("Guess a number: "))
if answer < guess:
print("The number is lower than that.")
elif answer > guess:
print("The number is higher than that")
else: # answer == guess
print("You win!")
break
guess_count += 1
elif guess_count == guesses:
guess = int(input("Guess a number: "))
if guess != answer:
print("You lose; the number was " + str(answer) + ".")
if guess == answer:
print("You win!")
break
It's very similar to your program, but has a couple break statements in there. This tells Python to immediately stop execution of that loop and go to the next block of code (nothing in this case). In this way you don't have to wait for the program to evaluate the conditions you specify for your while loop before starting the next loop. If this helped solve your problem, it'd be great of you to click the checkmark by my post
I'm taking my first-ever Python class and, like most Python classes, the last assignment is to create a guessing game from 1-100 that tracks the number of VALID tries. The element that I just cannot get (or find here on stackoverflow) is how to reject invalid user input. The user input must be whole, positive digits between 1 and 100. I can get the system to reject everything except 0 and <+ 101.
The only things I can think to do end up telling me that you can't have operators comparing strings and integers. I keep wanting to use something like guess > 0 and/or guess < 101. I've also tried to create some sort of function, but can't get it to work right.
# Generate random number
import random
x = random.randint(1,100)
# Prompt user for input
print("I'm thinking of a number from 1 to 100")
counter = 0
while True:
guess = input("Try to guess my number: ")
# Check if input is a positive integer and is not 0 or >=101
# this line doesn't actually stop it from being a valid guess and
# counting against the number of tries.
if guess == "0":
print(guess, "is not a valid guess")
if guess.isdigit() == False:
print(guess, "is not a valid guess")
else:
counter += 1
guess = int(guess)
# Begin playing
if guess > x:
print(guess, "is too high.")
elif guess < x:
print(guess, "is too low.")
else:
print(guess, "is correct! You guessed my number in", counter, "tries!")
import random
x = random.randint(1,100)
# Prompt user for input
print("I'm thinking of a number from 1 to 100")
counter = 0
while True:
guess = input("Try to guess my number: ")
try:
guess = int(guess)
if(100 > guess > 0):
counter += 1
guess = int(guess)
# Begin playing
if guess > x:
print(guess, "is too high.")
elif guess < x:
print(guess, "is too low.")
else:
print(guess, "is correct! You guessed my number in", counter, "tries!")
break
else:
print("Number not in range between 0 to 100")
except:
print("Invalid input")
# Generate random number
import random
x = random.randint(1,100)
# Prompt user for input
print("I'm thinking of a number from 1 to 100")
counter = 1
while True:
try:
guess = int(input("Try to guess my number: "))
if guess > 0 and guess < 101:
print("That's not an option!")
# Begin playing
elif guess == x:
print(guess, "is correct! You guessed my number in", counter, "tries!")
break
elif guess > x:
print(guess, "is too high.")
elif guess < x:
print(guess, "is too low.")

My instructor helped me out. (I posted to keep from needing that from the guy who's giving me the grade.) Here is what we came up with. I'm posting it to help out any future Python learner that may have this particular rejecting user input problem.
Thank you guys for posting SO FAST! Even though I needed the instructor's help, I would've looked even more incompetent without your insights. Now I can actually enjoy my holiday weekend. Have a great Memorial Day weekend!!!
import random
x = random.randint(1,100)
print("I'm thinking of a number from 1 to 100.")
counter = 0
while True:
try:
guess = input("Try to guess my number: ")
guess = int(guess)
if guess < 1 or guess > 100:
raise ValueError()
counter += 1
if guess > x:
print(guess, "is too high.")
elif guess < x:
print(guess, "is too low.")
else:
print(guess, "is correct! You guessed my number in", counter, "tries!")
break
except ValueError:
print(guess, "is not a valid guess")
Thank you for your patience everyone.
Thank you Ben10 for your answer. (posted below with my corrected print statements) My print statements were wrong. I needed to take the parenthesis out and separate the variable with commas on either side.
print("It only took you ", counter, " attempts!")
The number guessing game asks for hints after a certain number of responses as well as the option to type in cheat to have number revealed. One to last hints to to let the person guessing see if the number is divisible by another number. I wanted to have this hint available until the end of the game to help narrow down options of the number.
Again thank you everyone for your time and feedback.

I rewrite the code, to allow it to be more versitile. Noticed quite a few errors, like how you forgot to put a closing bracket at the end of a print statement. Also in the print statements you were doing String concatenation (where you combine strings together) incorrectly.

while counter < 5:
if counter == 3:
print("Nope. Do you have what it takes? If not, type in 'cheat' to have the random number revealed. ")

I have this basic code and what I want it to do is choose a random number, then it would ask the user to input a number from 0 to 100, the would give back results based on the number, such as number is too low or high. I keep switching things around but always get an error, this for 2.7:
import random
randomNumber = random.randrange(0,100)
guess = -1
guess = int(input('Enter a number between 0 and 100: ')
guess != randomNumber:
if guess < randomNumber
print('Your guess is too low.')
elif guess > randomNumber:
print('Your guess is too high.')
print('You win!')
First, you define guess twice. Just define it once. There is no need to make guess be equal to -1 if that won't be the original value anyways. Second, I believe you want to use a while loop to keep checking if the user has guessed the correct number. In this case, add another guess into the while loop to allow the player to continue guessing and to keep proper syntax.
Don't let the player win always with another condition. Use colons after each if/elif statement as well. As you are comparing a string (the input) and an integer, change the input() to int(input()). The final code should be something like:
import random
randomNumber = random.randrange(0, 100)
guess = None # Define guess
while guess != randomNumber: # Create loop
guess = int(input("Enter a number between 0 and 100")) # Change guess
if guess < randomNumber:
print "Your guess is too low."
elif guess > randomNumber:
print "Your guess is too high."
elif guess == randomNumber:
print "You win!" # Win message under correct condition
break # Exit the loop as game is finished
You're missing a colon after your if statement. You're also printing You win! regardless of the outcome. Put that inside an else statement. You don't need this line guess != randomNumber:, and you don't need guess=-1, and finally you're missing a closing paren as mentioned in comments.
import random
randomNumber = random.randrange(0,100)
guess = None
while guess != randomNumber:
guess = int(input('Enter a number between 0 and 100: '))
if guess == randomNumber:
break
elif guess < randomNumber:
print('Your guess is too low.')
elif guess > randomNumber:
print('Your guess is too high.')
print('You win!')
As usual, commenting your code reveals the error instantly
import random
# Pick a number between 0 and 99
randomNumber = random.randrange(0,100)
# initialize guess (hint: why?)
guess = -1
# Ask the user to guess a number (hint: balanced parentheses help)
guess = int(input('Enter a number between 0 and 100: ')
# What is this line supposed to be? Looks like the beginning of a loop here, but what kind?
guess != randomNumber:
# If the guess is less than the number, then tell the user
if guess < randomNumber
print('Your guess is too low.')
# Otherwise if the guess is higher than the number, tell the user
elif guess > randomNumber:
print('Your guess is too high.')
# Regardless, win the game. Wait whuh..?
print('You win!')
Try the following code:
import random
randomNumber = random.randrange(0,100)
guess = int(input("Enter a number between 0 and 100:"))
if guess < randomNumber:
print('Your guess is too low.')
elif guess > randomNumber:
print('Your guess is too high.')
else:
print('You win!')
(EDIT - removed some unecessary lines)
missing some formatting, and there's a few lines (guess != randomNumber:) that don't really do anything (and in that case, the colon would cause a SyntaxError).
import random
randomNumber = random.randrange(0,100)
guess = int(input('Enter a number between 0 and 100: '))
if guess < randomNumber:
print('Your guess is too low.')
elif guess > randomNumber:
print('Your guess is too high.')
else: # assuming you only want to print this if they guessed right
print('You win!')
