I strongly agree with this statement because i prefer the LC myself.
HOWEVER i've always lamented the verbosity of dir().
---------------------------
Case in Point
---------------------------
>>> dir([])
['__add__', '__class__', '__contains__', '__delattr__', '__delitem__',
'__delslice__', '__doc__', '__eq__', '__format__', '__ge__',
'__getattribute__', '__getitem__', '__getslice__', '__gt__',
'__hash__', '__iadd__', '__imul__', '__init__', '__iter__', '__le__',
'__len__', '__lt__', '__mul__', '__ne__', '__new__', '__reduce__',
'__reduce_ex__', '__repr__', '__reversed__', '__rmul__',
'__setattr__', '__setitem__', '__setslice__', '__sizeof__', '__str__',
'__subclasshook__', 'append', 'count', 'extend', 'index', 'insert',
'pop', 'remove', 'reverse', 'sort']
---------------------------
Do we really need to see all the built in methods EVERY time? I don't,
i've had them memorized for years. HOWEVER i do understand the fact
that n00bs need to see them every time. So why should old hats need to
type this every time...
>>> [x for x in dir([]) if not x.startswith('_')]
['append', 'count', 'extend', 'index', 'insert', 'pop', 'remove',
'reverse', 'sort']
Because we have plenty of room for args in this function...
>>> dir(verbose=False)
['append', 'count', 'extend', 'index', 'insert', 'pop', 'remove',
'reverse', 'sort']
Ahhh, i love it when a plan comes together!
