python 添加自己开发的模块

1. 定位模块文件地址的方法

import codecs

codecs.__file__

打印Python系统路径

import sys

sys.path

1. 添加自己的模块

here are a few ways. One of the simplest is to create a my-paths.pth file (as described here). This is just a file with the extension .pth that you put into your system site-packages




在site-packages中添加一个文件my-paths.pth，其中pth文件中添加自己的模块地址就行了
