Python_Notes

What I didn't know at that moment

1. What is all in python? It is a list of public objects of that module, as interpreted by import *. It overrides the default of hiding everything that begins with an underscore. In other words, it is a list of strings defining what symbols in a module will be exported when from <module> import * is used on the module. NOTE: __all__ only affects the from <module> import * behavior only. Members that are not mentioned in __all__ are still accessible from outside the module and can be imported with from <module> import <member>.

2. What is underscore? Following are different places where _ is used in Python.
