Python 创建和发布安装函数模块

1. create dir "nester" under C:\Users\eric\AppData\Local\Programs\Python\Python35-32\

2. create a nester.py under C:\Users\eric\AppData\Local\Programs\Python\Python35-32\nester\

"""this is a new fuction, which work for a list"""
def print_lol(the_list):
    """ one arguement is the_list"""
    for each_item in the_list:
        if isinstance(each_item,list):
            print_lol(each_item)
        else:
            print(each_item)

3. Run F5, Python解析器重置，加载了新的函数

 RESTART: C:\Users\eric\AppData\Local\Programs\Python\Python35-32\nester\nester.py
>>> movies = ["abc","ehll","asdfdsf"]
>>> print_lol(movies)
abc
ehll
asdfdsf
>>>

4. create setup.py  under C:\Users\eric\AppData\Local\Programs\Python\Python35-32\nester\

from distutils.core import setup

setup(
        name        = 'nester',
        version     = '1.0.0',
        py_modules  = ['nester'],
        author      = 'eric',
        author_email= 'eric@126.com',
        url         = 'http://126.com',
        description = 'a simple nested lists',

    )

5. create distribution under CMD or Shell

C:\Users\eric\AppData\Local\Programs\Python\Python35-32\nester>c:\Users\eric\AppData\Local\Programs\Python\Python35-32\python.exe setup.py sdist
running sdist
running check
warning: sdist: manifest template 'MANIFEST.in' does not exist (using default file list)

warning: sdist: standard file not found: should have one of README, README.txt

creating nester-1.0.0
making hard links in nester-1.0.0...
hard linking nester.py -> nester-1.0.0
hard linking setup.py -> nester-1.0.0
creating dist
creating 'dist\nester-1.0.0.zip' and adding 'nester-1.0.0' to it
adding 'nester-1.0.0\nester.py'
adding 'nester-1.0.0\PKG-INFO'
adding 'nester-1.0.0\setup.py'
removing 'nester-1.0.0' (and everything under it)

6. install nester moudle to your local

C:\Users\eric\AppData\Local\Programs\Python\Python35-32\nester>c:\Users\eric\AppData\Local\Programs\Python\Python35-32\python.exe setup.py install
running install
running build
running build_py
creating build
creating build\lib
copying nester.py -> build\lib
running install_lib
copying build\lib\nester.py -> c:\Users\eric\AppData\Local\Programs\Python\Python35-32\Lib\site-packages
byte-compiling c:\Users\eric\AppData\Local\Programs\Python\Python35-32\Lib\site-packages\nester.py to nester.cpython-35.pyc
running install_egg_info
Writing c:\Users\eric\AppData\Local\Programs\Python\Python35-32\Lib\site-packages\nester-1.0.0-py3.5.egg-info

7. import and test new moudle

>>> import nester
>>> cast = ['palin','cleese','book','jones']
>>> print_lol(cast)
Traceback (most recent call last):
  File "<pyshell#3>", line 1, in <module>
    print_lol(cast)
NameError: name 'print_lol' is not defined
>>> nester.print_lol(cast)
palin
cleese
book
jones
>>>
