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)
