推荐答案

来自 Python文档

该参数是模块名称，您不能指定文件扩展名(.py). module-name应该是一个有效的Python模块名称，但是实现可能并不总是强制执行此操作(例如，它可能允许您使用包含连字符的名称).

The argument is a module name, you must not give a file extension (.py). The module-name should be a valid Python module name, but the implementation may not always enforce this (e.g. it may allow you to use a name that includes a hyphen).

还允许使用包裹名称.当提供软件包名称而不是常规模块时，解释器将执行. main 作为主模块.这种行为故意类似于处理作为脚本参数传递给解释器的目录和zipfile.

Package names are also permitted. When a package name is supplied instead of a normal module, the interpreter will execute .main as the main module. This behaviour is deliberately similar to the handling of directories and zipfiles that are passed to the interpreter as the script argument.
