__init__.py 模块有啥用

[liujuanjuan1984]

How do you create a package so that the following reference will work?

p = mytools.myparser.MyParser()
Declare the myparser package in mytools.py
Create an init.py in the home dir
Inside the mytools dir create a init.py and myparser.py
Create a myparser.py directory inside the mytools directory
This can not be done
