Is there any way to make an implicit initializer for modules (not packages)? Something like:
#file: mymodule.py
def __init__(val):
global value
value = 5
And when you import it:
#file: mainmodule.py
import mymodule(5)

The __init__ method is the Python equivalent of the C++ constructor in an object-oriented approach. The __init__ function is called every time an object is created from a class. The __init__ method lets the class initialize the object's attributes and serves no other purpose. It is only used within classes.
The __init__.py files are required to make Python treat directories containing the file as packages. This prevents directories with a common name, such as string , unintentionally hiding valid modules that occur later on the module search path.
A module in Python is a file (ending in .py ) that contains a set of definitions (variables and functions) that you can use when they are imported. Modules are considered as objects, just as everything else is in Python.
The __init__.py file indicates that the files in a folder are part of a Python package. Without an __init__.py file, you cannot import files from another directory in a Python project.
The import statement uses the builtin __import__ function.
Therefore it's not possible to have a module __init__ function.
You'll have to call it yourself:
import mymodule
mymodule.__init__(5)
