You don't really need a virtualenv

When you develop a Python project, you need to install the project's dependencies.

Problem:

Virtualenvs help us isolate project dependencies, but things get tricky when it comes to nested venvs: One installs the virtualenv manager(like Pipenv or Poetry) using a venv encapsulated Python, and creates more venvs using the tool which is based on an encapsulated Python. One day a minor release of Python is out and one has to check all those venvs and upgrade them if required before they can safely delete the out-dated Python version.


Solution:

PEP 582 -- Python local packages directory
PDM -- A new Python package manager and workflow tool that leverages PEP 582 to get rid of virtualenv entirely. It installs dependencies into the local package directory package and makes Python interpreters aware of it with a very simple step.

In PDM, PEP 582 is not mandatory, you can also stick with virtualenv. PDM can detect existing venvs but not create new ones.

Python facts

——

The "return" and "yield" keywords can only be used inside functions.

The "nonlocal" keyword can only be used in a nested scope.


In contract, a star import can only be used at the module level.


Of course, "continue" and "break" only make sense inside a loop:

Python Steering Council is announced that
chosen to accept PEP 634, and its companion PEPs 635 and 636, collectively known as the
Pattern Matching PEPs.

Pattern matching feature is very challenging.

First time ever., long pending proposal was accepted and going to be a big change and will be ready for new release 3.10.

This is was proposed by Author of Python (he is one of the member for proposal )


Rejected proposals are 640 and 642.

Python integers are interesting because they are not just 32-bit or 64-bit integers that CPUs work with natively. Python integers are arbitrary-precision integers, also known as bignums. This means that they can be as large as we want, and their sizes are only limited by the amount of available memory.

Do you know what is IIFE in Python ?

IIFE - immediately invoked function execution:

Which you can use in lambda expression passing args values immediate right to expression.


(lambda x, y, z: x + y + z)(1, 2, 3)


Note : IIFE is actually concept from JavaScript

⌛⌛When you understand Underscores in Python, You will be knowing following concepts as well.

◌Name Mangling
◌Private variables (there is no private variables )
◌Dunder or Special or Magic methods
◌Usage of _ (underscore) for variable
