python - python有 'man'吗？

Question

我想知道是否有像“man.py”这样专用于 Python 的 CLI？

例如，

man.py os.system
> system(command) -> exit_status
>
> Execute the command (a string) in a subshell.

Answer 1

pydoc 模块提供了它:

$ python -m pydoc os.system
Help on built-in function system in os:

os.system = system(...)
    system(command) -> exit_status

    Execute the command (a string) in a subshell.
