dir() return an alphabetized list of names comprising (some of) the
attributes
of the given object, and of attributes reachable from it. It does not
return the parameter for a function.

Example: 

>>> dir(parser.ast2list)
['__call__', '__class__', '__cmp__', '__delattr__', '__doc__',
'__getattribute__
', '__hash__', '__init__', '__module__', '__name__', '__new__',
'__reduce__', '_
_reduce_ex__', '__repr__', '__self__', '__setattr__', '__str__']
>>> help(parser.ast2list)
Help on built-in function ast2list:

ast2list(...)
    Creates a list-tree representation of an ST.
>>>
Help return (...) instead parameter - why ?? 


In Python manual: 
st2list(ast[, line_info])

How can i get (ast[, line_info]) without manual ?
