如何从python的前一个函数中获取两个变量？


How to get two variables from the previous function in python?

本问题已经有最佳答案，请猛点这里访问。

我对python很陌生，所以我还在学习一些东西。但是我正在编写这段代码，我需要知道如何从"gethumanmove"函数中获取x和y变量，以便在"getpires"函数中使用它。

def getHumanMove(x,y):
    finished = False
    while not finished:
        x=int(input("Which pile would you like to take from?(1 or 2)"))
        y=int(input("How many would you like from pile"+ str(x)+"?"))
        if pile1 and pile2<y:
            print("pile" +str(x)+" does not have that many chips. Try again.")
        elif y==0:
            print("You must take at least one chip. Try again.")
        else:
            print("That was a legal move. Thank You.")
        finished = True
    return x,y

def getPiles(pile1, pile2):
    print("Here are the piles:")
    #################################Here is where I need to put the x, y variables
    pile1= pile1
    pile2= pile2
    if temp_x == 1:
        pile1= pile1- temp_y
        print("pile 1:", str(pile1))
        print("pile 2:", str(pile2))
    elif temp_x == 2:
        pile2= pile1- temp_y
        print("pile 1:", str(pile1))
        print("pile 2:", str(pile2))
        return pile1, pile2

##############################Main##############################
move= getHumanMove(pile1, pile2)

pile= getPiles(pile1, pile2)

打电话给GetPiles怎么样？

1
pile = getPiles(pile1, pile2, move)

然后在getpires定义中：

1
2
def getPiles(pile1, pile2, move):
    x, y = move

当函数返回两个值时，可以

1
value1, value2 = some_function(argument1, argument2, argument3, ...)

在value1和value2中存储这两个返回值。

您可以使用tuple解包：

1
2
move = getHumanMove(pile1, pile2)
pile = getPiles(*move)

或者分别获取每个变量，这样您也可以分别传递它们：

1
2
move1, move2 = getHumanMove(pile1, pile2)
pile = getPiles(move1, move2)

假设这就是你的意思：

1
2
x,y = getHumanMove(pile1, pile2)
pile1, pile2 = getPiles(x, y)
