https://realpython.com/python-modules-packages/ 在软件开发中,一个module是具有一些相关功能的软件集合,比如,当你在开发一个游戏时,可能会有一个模块负责game logic,而另一个module负责在屏幕上绘制对应的界面。每个module是一个不同的文件,可以单独编辑。 modules python中每一个单独的.py文件就是一个module,模...
在刚入门python时,模块化编程、模块、类库等术语常常并不容易理清。尤其是Modules(模块)和Packages(包),在import引用时很容易混淆出错。 实际上,Python中的函数(Function)、类(Class)、模块(Module)、包库(Package),都是为了实现模块化引用,让程序的组织更清晰有条理。1 👉通常,函数、变量、类存储在被称为模块(...

接下来我们介绍packages。 可以使用一个package来进一步组织模块。 package定义:Apython modulewhich contain submodules or recursively, subpackgaes. Technically, a package is a python module with an _path_ attribute. ---来自 请注意:包仍然是一个模块。作为用户来说,无需担心是导入模块还是包。实际上,一...
In summary, __all__ is used by both packages and modules to control what is imported when import * is specified. But the default behavior differs: For a package, when __all__ is not defined, import * does not import anything. For a module, when __all__ is not defined, import *...
You’ll learn about built-in modules from the standard library and popular third-party packages that enhance Python’s capabilities for both basic and advanced programming tasks. Protip: Use pip list or pip freeze to list all installed Python packages and modules. For tree-like visualization, fir...
注意到多级package的import,虽然该路径上的所有packages都被引入了,但是使用的时候仍然必须使用完整路径。 将package/_init_.py改成如下: AI检测代码解析 print "<<<in package1.__init__.py>>>" import package2 def say_hello(): print "Hi, my name is Forrest!" ...
Python Modules and PackagesModules and packages are two constructs used in Python to organise larger programs. This chapter introduces modules in Python, how they are accessed, how they are define and how Python finds modules...doi:10.1007/978-3-030-20290-3_25Hunt, John...
