python如何在初始化一个类时 知道参数的属性

例如 我要初始化Scrollbar
hbar = Scrollbar(orient='horizontal')
怎么知道orient这个参数有什么属性

help也没有列出参数的属性啊 只列出了参数
help(Scrollbar.__init__)
Help on function __init__ in module tkinter:

__init__(self, master=None, cnf={}, **kw)
Construct a scrollbar widget with the parent MASTER.

Valid resource names: activebackground, activerelief,
background, bd, bg, borderwidth, command, cursor,
elementborderwidth, highlightbackground,
highlightcolor, highlightthickness, jump, orient,
relief, repeatdelay, repeatinterval, takefocus,
troughcolor, width.
如何 call the method keys.

help(Scrollbar.config)
Help on function configure in module tkinter:

configure(self, cnf=None, **kw)

The values for resources are specified as keyword
arguments. To get an overview about
the allowed keyword arguments call the method keys.

help列出来的是python源文件中带的DocStrings。
但是，不可能把全部说明都放进python源文件里面吧？
想要获得详细的参数、属性说明，应该看相关的API文档吧。
