Python中__init__.py如何使用?,python__init__.py,2015/8/26 一


2015/8/26
一直以来对__init__.py在Python中的作用比较模糊,一致认为它大概的作用是: 让一个目录(directory)编程一个包(package),google之后的答案是:

The __init__.py files are required to make Python treat the directories as containing packages; this is done to prevent directories with a common name, such as string, from unintentionally hiding valid modules that occur later on the module search path. In the simplest case, __init__.py can just be an empty file, but it can also execute initialization code for the package or set the __all__ variable, described later.
