添加功能以直接从 python 子包导入某些功能

Question

Consider a regular python package with following fixed structure

myPackage/
├──__init__.py 
├──basic/
│  ├──__init__.py
│  ├──basicOne/
│  │   ├──__init__.py
│  │   ├──f1.py
│  │   └──f2.py
│  ├──a1.py
│  └──a2.py
└──README.md

If one wants to import some function foo() in f1.py , and roo() in a1.py , then one can use standard commands

from myPackage.basic.basicOne import f1

f1.foo()

and

from myPackage.basic import a1

a1.roo()

Suppose one wants to add a feature where function foo() and roo() can also be called this way

import myPackage as myPack
myPack.foo()
myPack.roo()

then what additional code should one write in the package? If such additional code is written, would it interfere with distributing and installing the top-level package, myPackage . Since there are many methods to distribute, lets fix the method to the one given in Packaging Python Projects .

Answer 1

Just go to the most top level __init__.py file and import what you need there:

from .basic.basicOne.f1 import foo
from .basic.a1 import roo
