4. Selenium2 自动化测试实战-基于Python语言-跨目录模块调用

projec/

|___model/

|      |___count.py

|      |___new_count.py

|___test.py

count.py

class A():    def add(self,a,b):        return a +b

new_count.py

     

from count import Aclass B (A):    def sub(self,a,b):        return a-b    result =B().add(2,5)print(result)

test.py

import syssys.path .append ("./model") #将model命令添加到系统环境变量下from model import new_counttest =new_count.B()test.add(2,4)

输出结果：
