The __dict__ attribute will return a dictionary object of module attributes, functions and other definitions and their respective values. Example: __dict__ Attribute Copy import math print(math.__dict__) Try it

Here, we can see a sorted list of names (along with add). All other names that begin with an underscore are default Python attributes associated with the module (not user-defined). For example, the __name__ attribute contains the name of the module. import example example.__name__ # ...
在Python中,一个.py文件就是一个模块(Module)。 使用模块有什么好处? 最大的好处是大大提高了代码的可维护性。 其次,编写代码不需要从零开始。当一个模块编写完毕,就可以被其他地方引用。我们自己在编写程序的时候,也经常会用到这些编写好的模块,包括Python内置的模块和来自第三方的模块。 所以,模块分为三种: ...
list.__dict__['__repr__'] 显示的是 <slot wrapper '__repr__' of 'list' object>。 所谓的MRO 即 Method Resolve Order,也是一个class 对象的属性解析顺序(继承情况下),class A(list) class B(list) class C(A) class D(C, B) 则D 的 mro 列表 是(D, C, A, B, list),保存在 PyType...
By the end of this tutorial, you’ll understand that:The Python subprocess module is used to run shell commands and manage external processes. You run a shell command using subprocess by calling subprocess.run() with the command as a list of arguments. subprocess.call(), subprocess.run(), ...
Why? Because, as reportedhere, when the interpreter shuts down, the module’s global variables are all set toNone. As a result, in the above example, at the point that__del__is invoked, the namefoohas already been set toNone.
