在 Python 3 中为函数分配变量名

Question

So I'm writing a program that, once finished, will have a user roll 2 dice and then keep a running sum of the values shown and assign some points to the values that are rolled, but I am running into a problem when first getting started. This is what I have so far:

def diceOne():
    import random
    a = 1
    b = 6
    diceOne = (random.randint(a, b))

def diceTwo():
    import random
    a = 1
    b = 6
    diceTwo = (random.randint(a, b))

def greeting():
    option = input('Enter Y if you would like to roll the dice: ')
    if option == 'Y':
        diceOne()
        diceTwo()
        print('you have rolled a: ' , diceOne, 'and a' , diceTwo)



greeting()

(after, I plan to do calculations like diceTwo + diceOne and do all the other stuff - i know this is very rough)

But when it runs, it does not give nice integer values as expect, it returns function diceOne at 0x105605730> and a <function diceTwo at 0x100562e18> Does anyone know how to get around this while still being able to assign variable names in order to later be able to perform calculations?

Answer 1

There are several problems with your code. I'll post this as an answer because it's more readable than a comment

1. Only import random once, not in every method
2. diceOne() and diceTwo() do the same thing, so just define one method dice()
3. return a value from dice() , not assign dice() to random.randint()

4. You can call dice() directly in your print statement

    import random def dice(): a = 1 b = 6 return random.randint(a, b) def greeting(): option = input('Enter Y if you would like to roll the dice: ') if option == 'Y': print('you have rolled a ' , dice(), 'and a ', dice()) greeting()

Answer 2

You have to return something from your functions for them to have an influence on anything outside of the functions themselves. Then, in your function greeting() you have to call the functions by calling diceOne() instead of diceOne .

Try:

def diceOne():
    import random
    a = 1
    b = 6
    return (random.randint(a, b))

def diceTwo():
    import random
    a = 1
    b = 6
    return (random.randint(a, b))

def greeting():
    option = input('Enter Y if you would like to roll the dice: ')
    if option == 'Y':
        diceOne()
        diceTwo()
        print('you have rolled a: ' , diceOne(), 'and a' , diceTwo())

greeting()
