#Lab 7-3 The Dice Game

#this function will get the random values

    elif winnerName == playerTwo:

初级程序员在这里，并试图完成一项任务。第19行返回错误: TypeError: inputNames()不接受任何参数(给定2个)。第19行: playerOne，playerTwo = inputNames(playerOne，playerTwo)。这条线是我的教授提供的，我想不出该怎么做。任何帮助都将不胜感激！

函数inputNames被定义为一个不带参数的函数，但是您在方法列表中向它传递了两个变量：

下面是你如何定义它的：

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

下面是你的名字：

playerOne, playerTwo = inputNames(playerOne, playerTwo)

你真正想要的是这个函数来返回玩家一和玩家二的名字。所以上面的这一行应该是：

playerOne, playerTwo = inputNames()

该函数必须在本地收集这两个名称，并返回这些名称，可能如下所示：

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
