How do I make python only ask for user input once in def main()?-CodePudding

Here's the code

# Number guessing game

# Import any libraries here
from random import randrange

#def user_integer():
 #   ''' get what user's integer here'''
  #  x = int(input("Enter integer to play"))


def random_int(size):
    """ This function takes in an integer size that indicates the
    length of the list of integers beginning at 1 and ending 
    at size, including size. It returns a random integer between 1 and size.
    """
    return randrange(1, size 1)

# Test out the function
#random_int(10)

def new_guess():
    '''user input for a new number'''
    x = input("what's your guess?")
    x = int(x)
    #while x!= -4:
     #   compare(user_num, computer_num)
    return x

def compare(user_num, computer_num):
    ''' compares size of numbers and prints winner'''
    user_num = new_guess()
    computer_num = int(random_int(1000))
    if user_num > computer_num:
        print ("user wins")
    elif user_num == computer_num:
        print ("it's a tie")
    elif user_num < computer_num:
        print ("robots win")
    else:
        print("wrong input")


def main():
    ''' control center, allowing me to use multiple functions to pass information '''
    # Write your algorithm here
    computer_num = random_int(1000)
    user_num = new_guess()
    print("You guessed", user_num)
    print("The robot's number is",computer_num)
    compare(user_num, computer_num)

    
main()

This gives me:

what's your guess? 85 #input

You guessed 85

The robot's number is 540 #random number

what's your guess? 85 #it makes user input again

robots win

Everything prints that is supposed to print. However, since I called user_num = new_guess(), it makes the user input a number once there and then again for the function compare(user_num, computer_num)

How do I make it so that a user only inputs a number once to get a response from compare(user_num, computer_num)?

Should I call user_num a new name once I get my guess in def main()?

CodePudding user response：

The problem is you're getting input for twice. In main function, you get computer_num random number and user_num input. And then you call compare() function, which have these both parameters.

You can delete 2 lines of code from compare() function. It should look like this:

def compare(user_num, computer_num):
    ''' compares size of numbers and prints winner'''
    if user_num > computer_num:
        print ("user wins")
    elif user_num == computer_num:
        print ("it's a tie")
    elif user_num < computer_num:
        print ("robots win")
    else:
        print("wrong input")

CodePudding user response：

It's because your calling your new_guess() function two times. Once in main() and another in compare
