如何在python中找到有关函数的信息？

我知道在R中你可以输入？"function_name".你是如何在python中做到这一点的？具体来说,我试图set_position在pyplot库中找到有关的信息.

Answer 1

help(function)

应该做的伎俩.

演示:

def func():
    """
    I am a function who doesn't do anything,
    I just sit in your namespace and crowd it up.
    If you call me expecting anything
    I'll just return to you the singleton None
    """
    pass

help(func)
