Learn how to use Python's if __name__ == "__main__" idiom to control code execution. Discover its purpose, mechanics, best practices, and when to use or avoid it. This tutorial explores its role in managing script behavior and module imports for clean an
In this quiz, you'll have the opportunity to test your knowledge of the __pycache__ folder, including when, where, and why Python creates these folders. In Short: It Makes Importing Python Modules Faster Even though Python is aninterpreted programming language, its interpreter doesn’t operate...
the code is works of course and I see that the directory "__pycache__" (where should store the compiled programme " sc.cpython-36.pyc ") is created in the same directory where " sc.py " is placed. But if I run the script simple from the command line like this: ./sc.py 'Hello...
While Python provides a C API for thread-local storage support; the existing Thread Local Storage (TLS) API has used int to represent TLS keys across all platforms. This has not generally been a problem for officially-support platforms, but that is neither POSIX-compliant, nor portable in any...

The os.DirEntry class and relevant classes in pathlib have also been updated to implement os.PathLike. The hope is that updating the fundamental functions for operating on file system paths will lead to third-party code to implicitly support all path-like objects without any code changes, or ...

Filesystem support in OS and pathlib has been improved, and a few modules now run faster. The language improvements are centered on simplicity of usage since several limitations on f-strings have been removed. The revised sort boundary linguistic structure and type explanation improve ergonomics for...

When the generator function is called, the function body is not executed at all. Python system will create a generator iterator, which wraps the generator function body inside the iterator. This iterator is then returned to the caller.
