在函数中返回变量

我有这个程序,我想使用这些函数来询问高度,宽度和长度,并将它们作为单独的变量,以便我可以使用它们绘制龟图形。还有我的getColor函数我想要返回bin并且可以单独使用颜色,这样我就可以将它们应用于龟图形中。我对参数感到困惑;他们会在这里有用吗?

def main():

    print ("The bin dimensions are: ",(getDim()))
    numofcans = getCans()
    print ("You are recycling ",numofcans,"cans.")
    print("Your bin color is ",getColor())


def getDim():

    height = int(input("Enter the bins height (40 to 60): "))
    width = int(input("Enter the bins width (40 to 60): "))
    length = int(input("Enter the bins length (40 to 60): "))
    while height and width and length not in range(40,61):
        print("You entered a wrong value")
        height = int(input("Enter the height (40 to 60: "))
        width = int(input("Enter the width(40 to 60: "))
        length = int(input("Enter the length (40 to 60: "))
    if height and width and length in range(40,61):
        return height, width, length

def getCans():

    cans = int(input("Enter the amount of cans (10,1000): "))
    if cans in range(10,1001):
        return cans
    while cans not in range(10,1001):
        cans = int(input("Invalid number, please enter the amount of cans (10,1000): "))
        return cans

def getColor():
    bincolor = int(input("Color menu \n 1 = 'blue' \n 2 = 'red' \n 3 = 'green' \n 4 = 'magenta' \nPick the bin color: "))
    while bincolor not in range(1,5):
        bincolor = int(input("Color menu \n 1 = 'blue' \n 2 = 'red' \n 3 = 'green' \n 4 = 'magenta' \nPick the bin color: "))
    while bincolor in range(1,5):
        if bincolor == 1:
            bincolor = "blue"
        elif bincolor == 2:
            bincolor = "red"
        elif bincolor == 3:
            bincolor = "green"
        elif bincolor == 4:
            bincolor = "magenta"


    cancolor = int(input("Color menu \n 1 = 'blue' \n 2 = 'red' \n 3 = 'green' \n 4 = 'magenta' \nPick the can color: "))
    while cancolor not in range(1,5):
        cancolor = int(input("Color menu \n 1 = 'blue' \n 2 = 'red' \n 3 = 'green' \n 4 = 'magenta' \nPick the can color: "))

    while cancolor in range(1,5):
        if cancolor == 1:
            cancolor = "blue"
        elif cancolor == 2:
            cancolor = "red"
        elif cancolor == 3:
            cancolor = "green"
        elif cancolor == 4:
            cancolor = "magenta"
        return bincolor, cancolor






main()

回溯:

>>> 
Enter the bins height (40 to 60): 45
Enter the bins width (40 to 60): 46
Enter the bins length (40 to 60): 47
The bin dimensions are:  (45, 46, 47)
Enter the amount of cans (10,1000): 101
You are recycling  101 cans.
Color menu 
 1 = 'blue' 
 2 = 'red' 
 3 = 'green' 
 4 = 'magenta' 
Pick the bin color: 1
Color menu 
 1 = 'blue' 
 2 = 'red' 
 3 = 'green' 
 4 = 'magenta' 
Pick the can color: 3
Your bin color is  ('blue', 'green')

类似

colors = getColor()

first = colors[0]
second = colors[1]

应该做的伎俩

希望我没有弄错,现在没有蟒蛇。

您已经作为元组返回,因此您只需调用函数并将其解压缩为新变量而不是打印它们:

def main():
    height, width, length = getDim()
    numofcans = getCans()
    bincolor, cancolor = getColor()
    # go on to do rest of program
    ...
