Create reusable codes across Projects and potentially ShareIt!

I am programming in modules, and it is easy to share *.py within a project. How?

• Always code in a def or a class. Never code outside one.
• For main code, never code outside a block, but code main code inside if _<i>name_</i> == '__main__':
• Share using import ... or from ... import ...

But sharing across projects is a different story, but today, I found out how:- https://python-packaging.readthedocs.io/en/latest/

• When you have done the packaging, you can run pip install -e . to share it for any *.py files you will run in the future.
• This will also facilitate others to run pip install ., and they can use your git now. (They will have to clone your git first, though.)
• You can publish on PyPI using python setup.py register
• Editing setup.py a bit, it is py2app/py2exe.

Good luck modular programming!
