The core principle governing command-line argument reception in Python is the separation of input reception from input processing, where the operating system transmits arguments as a string sequence to the interpreter without intrinsic semantic interpretation. Formally defined within the domain of computational linguistics and software architecture, this mechanism utilizes the `sys.argv` list, which strictly adheres to the convention of the first element representing the executable path and subsequent elements representing user-provided parameters. This theoretical framework establishes that while the mechanism for argument acquisition is standardized across general-purpose interpreters, the responsibility for type conversion, parsing, and logic application rests entirely on the implementer, distinguishing program-level inputs from function-level arguments.
