Question

我必须为学校编写一个程序，到目前为止，我有下面的代码，但是当我尝试运行它时，它说有一个错误，并且未定义compute_Area。

# This program will calculate and compare the areas of
# two rectangles and display which is the greater area
def main():
    length1 = int(input('Length of rectangle one: '))
    width1 = int(input('Width of rectangle one: '))
    area1 = compute_area(length1, width1)
    length2 = int(input('Length of rectangle two: '))
    width2 = int(input('Width of rectangle two: '))
    area2 = compute_Area(length2, width2)
    comparison_Area(area1, area2)
main()

def compute_Area():
    area = length * width
    return area

def comparison_Area():
    if area1 > area2:
        print()
        print('The area of rectangle one is: ', area1)
        print('The area of rectangle two is: ', area2)
        print('Rectangle one\'s area is greater.')
    elif area1 < area2:
        print()
        print('The area of rectangle one is: ', area1)
        print('The area of rectangle two is: ', area2)
        print('Rectangle two\'s area is greater.')
    elif area1 == area2:
        print()
        print('The area of rectangle one is: ', area1)
        print('The area of rectangle two is: ', area2)
        print('Rectangle\'s areas are equal.')

Answer 1

正如usr2564301在评论中所说，您正在调用一个名为“ compute_area”的函数，但是您将该函数定义为compute_Area（）

另外，如果要向函数中传递“ length1”和“ width1”，则需要在函数声明中声明（要传递2个变量）

Answer 2

不是您问题的答案，而是对懒惰人的暗示；）通常，如果您必须多次编写完全相同的行，则可以简化操作。

代替：

def comparison_area():
    if area1 > area2:
        print()
        print('The area of rectangle one is: ', area1)
        print('The area of rectangle two is: ', area2)
        print('Rectangle one\'s area is greater.')
    elif area1 < area2:
        print()
        print('The area of rectangle one is: ', area1)
        print('The area of rectangle two is: ', area2)
        print('Rectangle two\'s area is greater.')
    elif area1 == area2:
        print()
        print('The area of rectangle one is: ', area1)
        print('The area of rectangle two is: ', area2)
        print('Rectangle\'s areas are equal.')

您也可以只写：

def comparison_area():
    print()
    print('The area of rectangle one is: ', area1)
    print('The area of rectangle two is: ', area2)
    if area1 > area2:
        print('Rectangle one\'s area is greater.')
    elif area1 < area2:
        print('Rectangle two\'s area is greater.')
    elif area1 == area2:
        print('Rectangle\'s areas are equal.')

第二个功能完全相同。
