函数定义与函数的调用/自定义模块的调用等

定义一个MathLib.py文件

import math
def RectArea(width,height):area=width*heightreturn areadef CircleArea(radius):area=math.pi*radius*radiusreturn areaprint("MathLib Module Name:",__name__)
if __name__=="__main__":print(RectArea(2,3))print(CircleArea(2))

再定义一个Test.py文件

import MathLib
w=12
h=20
r=2
print("Test Module Name:",__name__)
print(MathLib.RectArea(w,h))
print(MathLib.CircleArea(r))
