I'm doing some Python exercises and I came across a frustrating error:
line 18, in <module>
modulo()
NameError: name 'modulo' is not defined
Code is below:
number = input("Please enter a number: ")
if number.isdigit():
def modulo():
answer = int(number) % 2
if answer == 0:
print("Your number, " + number + " is even.")
elif answer > 0:
print("Your number, " + number + " is odd.")
else:
print("Error. Please try again.")
else:
print("Please try again")
modulo()
Make modulo accept an argument, define it outside the if-statement
def modulo(num):
answer = int(num) % 2
if answer == 0:
print("Your number, " + num + " is even.")
elif answer > 0:
print("Your number, " + num + " is odd.")
else:
print("Error. Please try again.")
number = input("Please enter a number: ")
if number.isdigit():
modulo(number)
else:
print("Please try again")
You should write your function outside the if statement, in this case the function will be defined ONLY if number.isdigit() is True.

I'm very new to programming and am starting off with python. I was tasked to create a random number guessing game. The idea is to have the computer guesses the user's input number. Though I'm having a bit of trouble getting the program to recognize that it has found the number. Here's my code and if you can help that'd be great! The program right now is only printing random numbers and won't stop even if the right number is printed that is the problem
import random
tries = 1
guessNum = random.randint(1, 100)
realNum = int(input("Input a number from 1 to 100 for the computer to guess: "))
print("Is the number " + str(guessNum) + "?")
answer = input("Type yes, or no: ")
answerLower = answer.lower()
if answerLower == 'yes':
if guessNum == realNum:
print("Seems like I got it in " + str(tries) + " try!")
else:
print("Wait I got it wrong though, I guessed " + str(guessNum) + " and your number was " + str(realNum) + ", so that means I'm acutally wrong." )
else:
print("Is the number higher or lower than " + str(guessNum))
lowOr = input("Type in lower or higher: ")
lowOrlower = lowOr.lower()
import random
guessNum2 = random.randint(guessNum, 100)
import random
guessNum3 = random.randint(1, guessNum)
while realNum != guessNum2 or guessNum3:
if lowOr == 'higher':
tries += 1
import random
guessNum2 = random.randint(guessNum, 100)
print(str(guessNum2))
input()
else:
tries += 1
import random
guessNum3 = random.randint(1, guessNum)
print(str(guessNum3))
input()
print("I got it!")
input()
How about something along the lines of:
import random
realnum = int(input('PICK PROMPT\n'))
narrowguess = random.randint(1,100)
if narrowguess == realnum:
print('CORRECT')
exit(1)
print(narrowguess)
highorlow = input('Higher or Lower Prompt\n')
if highorlow == 'higher':
while True:
try:
guess = random.randint(narrowguess,100)
print(guess)
while realnum != guess:
guess = random.randint(narrowguess,100)
print(guess)
input()
print(guess)
print('Got It!')
break
except:
raise
elif highorlow == 'lower':
while True:
try:
guess = random.randint(1,narrowguess)
print(guess)
while realnum != guess:
guess = random.randint(1,narrowguess)
print(guess)
input()
print(guess)
print('Got It!')
break
except:
raise
This code is just a skeleton, add all of your details to it however you like.
I don't know what's wrong with it.. I run it and I'm able to input a number but then it stops working. It says, "TypeError: play_game() missing 1 required positional argument: 'limit.' But I'm not sure what's missing there??
#!/usr/bin/env python3
import random
def display_title():
print("Guess the number!")
print()
def get_limit():
limit = int(input("Enter the upper limit for the range of numbers: "))
return limit
def play_game(limit):
number = random.randint(1, limit)
print("I'm thinking of a number from 1 to " + str(limit) + "\n")
while True:
guess = int(input("Your guess: "))
if guess < number:
print("Too low.")
count += 1
elif guess >= number:
print("Too high.")
count += 1
elif guess == number:
print("You guessed it in " + str(count) + " tries.\n")
return
def main():
display_title()
again = "y"
while again.lower() == "y":
limit = get_limit()
play_game()
again = input("Play again? (y/n): ")
print()
print("Bye!")
# if started as the main module, call the main function
if __name__ == "__main__":
main()
You have defined your play_game function to take limit as a parameter, but when you call this function in your main loop, you don't supply a value in the brackets of play_game().
You could either try adding that limit value that you've specified by calling it like
play_game(25)
Or, based on your code, since you're asking the user to provide a limit, call it like:
play_game(limit)
Or, if you want to be able to call play_game() without setting a limit, then change your play_game definition line to something like:
def play_game(limit=25):
Which will set a default value of 25 whenever that function is called without supplying the limit value.
Yes, play_game() needs the parameter limit. I've done a quick check on your code, and there is some additional problem
the count variable isn't initialized
you calculate the random number in every step
guess > number should be used instead of guess >= number
Here is the fixed code, it works for me. I hope it will be usefull:
import random
count = 0
number = -1
def display_title():
print("Guess the number!")
print()
def get_limit():
limit = int(input("Enter the upper limit for the range of numbers: "))
return limit
def play_game(limit):
global number, count
if number == -1:
number = random.randint(1, limit)
print("I'm thinking of a number from 1 to " + str(limit) + "\n")
while True:
guess = int(input("Your guess: "))
if guess < number:
print("Too low.")
count += 1
elif guess > number:
print("Too high.")
count += 1
elif guess == number:
print("You guessed it in " + str(count) + " tries.\n")
return
display_title()
again = "y"
while again.lower() == "y":
limit = get_limit()
play_game(limit)
again = input("Play again? (y/n): ")
print()
print("Bye!")
In your main you are calling playgame() without providing a limit as an argument.
Your main should look something like
def main():
display_title()
again = "y"
while again.lower() == "y":
limit = get_limit()
play_game(10)
again = input("Play again? (y/n): ")
print()
print("Bye!")
import random
import time
print ("Welcome to the Game")
print ("You must complete the next 10 Multiplication Questions to be truly ready for the challenges of life")
print ("")
choice = input("Are you ready? Y / N: ")
print("")
def play():
while questions != 10:
num1 = random.randrange(9,17)
num2 = random.randrange(6,17)
print("What does " + str(num1) + " x " + str(num2) + " = ")
guess1 = input("Your guess?: ")
answer1 = (num1*num2)
if int(guess1) == answer1:
print("Correct")
time.sleep(1)
counter = counter + 1
questions = questions + 1
print("")
else:
print("Your answer was Wrong")
time.sleep(1)
print("The real answer was")
time.sleep(1)
print (str(answer1))
questions = questions + 1
print("")
if questions == 10:
print ("You got " + str(counter) + " out of 10")
return
play()
From the information available for now, I would say that this is because you did not assign any value for
questions
variable
To solve this, simply add
questions = 10 # or other value you may want
at the very start of the play() function
You need to initialize questions variable to 0 before while loop and also initialize counters variable to 0 and return statement should be outside while loop.
Below is the corrected code
import random
import time
print ("Welcome to the Game")
print ("You must complete the next 10 Multiplication Questions to be truly ready for the challenges of life")
print ("")
choice = input("Are you ready? Y / N: ")
print("")
def play():
#initialization
questions,counter =0,0
while questions != 10:
num1 = random.randrange(9,17)
num2 = random.randrange(6,17)
print("What does " + str(num1) + " x " + str(num2) + " = ")
guess1 = input("Your guess?: ")
answer1 = (num1*num2)
if int(guess1) == answer1:
print("Correct")
time.sleep(1)
counter = counter + 1
questions = questions + 1
print("")
else:
print("Your answer was Wrong")
time.sleep(1)
print("The real answer was")
time.sleep(1)
print (str(answer1))
questions = questions + 1
print("")
if questions == 10:
print ("You got " + str(counter) + " out of 10")
# return outside while loop
return
play()
An example for you:
#!/usr/bin/env python3.6
import time
from random import randrange
def play():
counter = 0
for i in range(10):
num1 = randrange(9, 17)
num2 = randrange(6, 17)
print(f"What does {num1} x {num2} = ")
guess = input("Your guess?: ")
answer = str(num1 * num2)
if guess == answer:
print("Correct\n")
counter += 1
else:
print("Your answer was Wrong")
print(f"The real answer was {answer}\n")
time.sleep(0.5)
print("You got " + str(counter) + " out of 10")
def main():
print(
"Welcome to the Game\n"
"You must complete the next 10 Multiplication Questions "
"to be truly ready for the challenges of life\n"
)
choice = input("Are you ready? Y / N: ")
if choice.upper() == "N":
return
print()
play()
if __name__ == "__main__":
main()
import random
four_digit_number = random.randint(1000, 9999) # Random Number generated
def normal():
four_digit = str(four_digit_number)
while True: # Data Validation
try:
guess = int(input("Please enter your guess: "))
except ValueError or len(str(guess)) > 4 or len(str(guess)) < 4:
print("Please enter a 4 digit number as your guess not a word or a different digit number")
else:
break
guess = str(guess)
counter = 0
correct = 0
while counter < len(four_digit):
if guess[counter] in four_digit:
correct += 1
counter += 1
if correct == 4:
print("You got the number correct!")
else:
print("You got " + str(correct) + " digits correct")
normal()
I don't understand why it says the index is not in range. When I use 0 instead of actually using counter it works. This only happens when I enter a value under 4 and when I enter a value over 4 the loop does not restart but it breaks out of the loop.
I would propose such a solution:
def normal():
four_digit = str(four_digit_number)
while True: # Data Validation
try:
guess = str(int(input("Please enter your guess: ")))
assert len(guess) == 4
except (ValueError, AssertionError):
print("Please enter a 4 digit number as your guess not a word or a different digit number")
else:
break
correct = sum(a == b for a, b in zip(four_digit, guess))
if correct == 4:
print("You got the number correct!")
else:
print("You got " + str(correct) + " digits correct")
#This will loop the try statement until an integer is entered as the guess1 variable
while True:
#The try statement will see if the guess variable is given an integer value,
#if not then it will print "You did not enter an integer. This is not a
#valid answer
try:
#This will allow the user to enter their answer and
#store it in the guess1 variable
guess1 = int(input(""))
#This will break the while loop if an integer is entered as the guess1 variable
break
except ValueError:
print("You did not enter an integer. This is not a valid answer. Please enter a valid integer")
print("Answer the quesiton appropiately" + "What is " + (str(first2) + op + str(second2) + "?")
if guess1 == answer1:
#If the guess1 variable is equal to the answer1 variable, then
#"Correct!" will be printed and one point would be
#added to the score
print("Correct!")
score += 1
else:
#Else "Incorrect" would be printed
print ("Incorrect")
The shell states that there is an invalid syntax with the colon when I typed 'guess1 == answer1:'.
The problem is that you didn't close a tag on the second line in your except statement. Add an extra ")" to the end.
print("Answer the quesiton appropiately" + "What is " + (str(first2) + op + str(second2) + "?"))
