Python中引入自定义路径下的用户自定义类

Python中引入自定义路径下的用户自定义类

自定义类如下:

import math

class Circle:

# Construct a circle object

def__init__(self, radius = 1):

self.radius = radius

def getPerimeter(self):

return 2 * self.radius * math.pi

def getArea(self):

return self.radius * self.radius * math.pi

def setRadius(self, radius):

self.radius = radius

测试类如下:

import sys

sys.path.append(r'/home/MyTrain/Python/Class')

from Circle import Circle

c = Circle(5)

print("Redius: ", c.radius)

print("Perimeter: ", c.getPerimeter())

print("Area: ", c.getArea())

>>python test_circle.py

运行结果:

('Redius: ', 5)

('Perimeter: ', 31.415926535897931) ('Area: ', 78.539816339744831)
