package 就是由多个.py文件或package有序组成的一个包。其中__init__.py必须存在,python才会认为这个文件夹的组成是一个package。 for example sound/ Top-level package __init__.py Initialize the sound package formats/ Subpackage for file format conversions __init__.py wavread.py wavwrite.py aiffrea...
包(Package): Packages are a way of structuring Python’s module namespace by using “dotted module names”. A package is a collection of python modules under a common namespace. 简单来讲,package是Module的集合,一个package由一个或多个Module构成。 库(Library): Library是Package的集合,一个Library...

此处,简单总结一下,module,library,package之间的大概区别。 Python中的module的简介 module,中文翻译为:模块 Python中的module,说白了,就是Python文件,而python文件一般后缀为py,所以就是你的xxx.py而已。 library简介 library,中文翻译为:库,也常称为:库文件 ...

import sysprint('\n'.join(sys.path))import package_B.module_bprint(package_B.module_b.add(1, 2))执行指令python3 -m package_A.module_a，你将看到以下结果：% python3 -m package_A.module_a/Users/slz/dev/src/digolds_sample/packages/Library/Frameworks/Python.framework/Versions/3.8/lib/...
/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/requests/__init__.py 也就是说,当Python执行import requests的时候,它会到以下目录去查找requests模块: /Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages ...
As we’ll see, package imports are also sometimes required to resolve import ambiguities when multiple program files of the same name are installed on a single machine. Because it is relevant to code in packages only, we’ll also introduce Python’s recent relative imports model and syntax ...
The parent-child relationship of processes is where the sub in the subprocess name comes from. When you use subprocess, Python is the parent that creates a new child process. What that new child process is, is up to you. Python subprocess was originally proposed and accepted for Python 2.4...
