Having trouble with getting a function to call. The same function works in a similar program. What am I missing here?

I can't get the try_again() function to call correctly. I keep getting the following error.

Traceback (most recent call last): File "/Users/jasonladieu/Desktop/Untitled.py", line 54, in <module> start_game() File "/Users/jasonladieu/Desktop/Untitled.py", line 50, in start_game com_random_number_game(1, 10) File "/Users/jasonladieu/Desktop/Untitled.py", line 22, in com_random_number_game try_again() File "/Users/jasonladieu/Desktop/Untitled.py", line 4, in try_again again = input("Would you like to play again?\n") File "<string>", line 1, in <module> NameError: name 'yes' is not defined Jasons-iMac:Desktop jasonladieu$

Here is my code:

import random

def try_again():
    again = input("Would you like to play again?\n")
    again = str(again.upper())
    if again == "YES":
        return com_random_number_game(1, 10)
    else:
        quit()




def com_random_number_game(a, b):
    guess = random.randint(a, b)
    print("Welcome to the number guessing game.")
    user_num = input("Enter a number between " + str(a) + " and " + str(b) + " for the computer to guess.\n")
    user_num = int(user_num)

    if guess == user_num:
        print("The computer guessed your number! The computer guessed " + str(guess) + ".")
        try_again()
    if guess < user_num:
        low_guess = guess + 1
        print("The computer guessed lower than your number. The computer guessed " + str(guess) + ". Time to guess again!\n")
        guess_two = random.randint(low_guess, b)
        if guess_two == user_num:
            print("The computer guessed your number! The computer guessed " + str(guess_two) + ".")
            try_again()
        else:
            print("The computer did not guess your number. The computer guessed " + str(guess_two) + ".")
            try_again()
    if guess > user_num:
        high_guess = guess - 1
        print("The computer guessed higher than your number. The computer guessed " + str(guess) + ". Time to guess again!\n")
        guess_two = random.randint(a, high_guess)
        if guess_two == user_num:
            print("The computer guessed your number! The computer guessed " + str(guess_two) + ".")
            try_again()
        else:
            print("The computer did not guess your number. The computer guessed " + str(guess_two) + ".")
            try_again()
    else:
        print("Something is wrong!")
        quit()

I copied over your code into atom.io, and ran the program in Hyper (Terminal), and it works. How were you testing the code?

One thing I noticed in your com_random_number_game() method, you had a duplicate if, else block, and your last else statement:

else: print("Something is wrong!") quit()

doesn't really make sense. You have that functionality already in your try_again() method, so you can probably just delete that block.

Here's the code I used to test it in the terminal. Just in case.

import random

def try_again (): again = input("Would you like to play again?\n") again = str(again.upper()) if again == "YES": return com_random_number_game(1,10) else: quit()

def com_random_number_game(a, b):

guess = random.randint(a, b)
print("Welcome to the number guessing game.")

user_num = input("Enter a number between " + str(a) + " and " + str(b) + " for the computer to guess.\n")
user_num = int(user_num)

if guess == user_num:
    print("The computer guessed your number! The computer guessed " + str(guess) + ".")
    try_again()

elif guess < user_num:
    low_guess = guess + 1
    print("The computer guessed lower than your number. The computer guessed " + str(guess) + ". Time to guess again!\n")
    guess_two = random.randint(low_guess, b)

elif guess > user_num:
    high_guess = guess - 1
    print("The computer guessed higher than your number. The computer guessed " + str(guess) + ". Time to guess again!\n")
    guess_two = random.randint(a, high_guess)

if guess_two == user_num:
    print("The computer guessed your number! The computer guessed " + str(guess_two) + ".")
    try_again()
else:
    print("The computer did not guess your number. The computer guessed " + str(guess_two) + ".")
    try_again()

Hi David,

Thanks for you help. I was running the Python launcher when I was receiving those error codes. Any idea why? And that second block of code is there to run the game a second time with new parameters based on the computers first guess.

Here is the error code I'm getting from launcher (terminal):

The computer did not guess your number. The computer guessed 3.
Would you like to play again?
yes
Traceback (most recent call last):
  File "/Users/jasonladieu/Desktop/Computer_number_game.py", line 49, in <module>
    com_random_number_game(1, 10)

    try_again()
  File "/Users/jasonladieu/Desktop/Computer_number_game.py", line 4, in try_again
    again = input("Would you like to play again?\n")
  File "<string>", line 1, in <module>
NameError: name 'yes' is not defined

I'm not familiar with launcher terminal, but if the code is correct and the program runs on other terminal programs, then it could be a bug in the launcher terminal program itself. Did you try to run the code on a different terminal to see if it works?
