What is __ init __ in Python?
__init__ The __init__ method is similar to constructors in C++ and Java . Constructors are used to initialize the object’s state. The task of constructors is to initialize(assign values) to the data members of the class when an object of class is created. It is run as soon as an object of a class is instantiated.

Intra-package References¶ When packages are structured into subpackages (as with the sound package in the example), you can use absolute imports to refer to submodules of siblings packages. For example, if the module sound.filters.vocoder needs to use the echo module in the sound.effects package, it can use from sound.effects import echo .
