初学者程序员在这里尝试完成作业。第19行返回错误:TypeError:inputNames()不带参数(给定2)。第19行:playerOne,playerTwo = inputNames(playerOne,playerTwo)。这条线由我的教授提供,我无法弄清楚如何使它工作。任何帮助将不胜感激!

答案 0 :(得分:3)

函数inputNames被定义为不带参数的函数,但是你在方法列表中传递了两个变量:

这是你如何定义它:

def inputNames():
    inputNames = string('Enter your names: ')
    return playerOne, playerTwo  

以下是您的称呼方式:

playerOne, playerTwo = inputNames(playerOne, playerTwo)

你真正想要的是这个函数返回玩家1和玩家2的名字。所以上面的行应该是:

playerOne, playerTwo = inputNames()

并且函数必须在本地收集这两个名称并返回它们,可能是这样的:

def inputNames():
    p1 = str(raw_input("Enter the name for player one: "))
    p2 = str(raw_input("Enter the name for player two: "))
    return p1, p2
