Question

我试图将变量设置为用户输入的字符串输入。之前我做过类似的类似操作，通过将变量设置为用户输入的整数输入并尝试复制它并将其从int（）更改为str（）但它没有工作。这是我到目前为止所拥有的：

import time

def main():
    print(". . .")
    time.sleep(1)
    playerMenu()
    Result(playerChoice)
    return

def play():
    playerChoice = str(playerMenu())
    return playerChoice


def playerMenu():
    print("So what will it be...")
    meuuSelect = str("Red or Blue?")
    return menuSelect


def Result():
    if playerChoice == Red:
        print("You Fascist pig >:c")
    elif playerChoice == Blue:
        print("QUICK, BEFORE YOU PASS OUT, WHAT DOES IT TASTE LIKE?!?")
        return 

main()

当我运行它时，它告诉我没有定义playerChoice。我不明白为什么它告诉我这个，因为我清楚地将playerChoice =设置为用户的字符串输入

你的函数返回值（好）但你没有做任何事情（坏）。您应该将值存储在变量中，并将它们传递给需要使用它们的任何人：

def main():
    print(". . .")
    time.sleep(1)
    choice = playerMenu()
    Result(choice)
    # no need for "return" at the end of a function if you don't return anything

def playerMenu():
    print("So what will it be...")
    menuSelect = input("Red or Blue?")  # input() gets user input
    return menuSelect

def Result(choice):
    if choice == "Red":                 # Need to compare to a string
        print("You Fascist pig >:c")
    elif choice == "Blue":
        print("QUICK, BEFORE YOU PASS OUT, WHAT DOES IT TASTE LIKE?!?")

main()

如何将变量设置为字符串输入python 3.5？
