This PEP defines semantics for executing any Python module as a script, either with the -m command line switch, or by invoking it via runpy.run_module(modulename).| Python Enhancement Proposals (PEPs)
Interactive Mode: There are two variants of the interactive REPL. The classic basic interpreter is supported on all platforms with minimal line control capabilities. On Windows, or Unix-like system...| Python documentation
Source code: Lib/runpy.py The runpy module is used to locate and run Python modules without importing them first. Its main use is to implement the-m command line switch that allows scripts to be lo...| Python documentation
In Python, the special name__main__ is used for two important constructs: the name of the top-level environment of the program, which can be checked using the__name__ == '__main__' expression; and,...| Python documentation
Source code: Lib/site.py This module is automatically imported during initialization. The automatic import can be suppressed using the interpreter’s-S option. Importing this module normally appends...| Python documentation
This module provides access to some variables used or maintained by the interpreter and to functions that interact strongly with the interpreter. It is always available. Unless explicitly noted oth...| Python documentation
Invoking the Interpreter: The Python interpreter is usually installed as/usr/local/bin/python3.13 on those machines where it is available; putting/usr/local/bin in your Unix shell’s search path mak...| Python documentation
Source code: Lib/timeit.py This module provides a simple way to time small bits of Python code. It has both a Command-Line Interface as well as a callable one. It avoids a number of common traps fo...| Python documentation
