:mod:`__main__` --- Top-level script environment ================================================ .. module:: __main__ :synopsis: The environment where the top-level script is run. This module represents the (otherwise anonymous) scope in which the interpreter's main program executes --- commands read either from standard input, from a script file, or from an interactive prompt. It is this environment in which the idiomatic "conditional script" stanza causes a script to run:: if __name__ == "__main__": main()
