Python source file

A .py file contains Python source code in plain text. The Python interpreter reads the file and runs the code directly, without a separate compile step. Developers write scripts, modules, and full programs in this format. A text editor can open and change the file. Python is one of the most used programming languages, thus .py files are common on many systems.
