 >>> def b1(a):
...     return a
...
 >>> dir()
['__builtins__', '__doc__', '__name__', 'b1']
 >>> globals().keys()
['__builtins__', '__name__', '__doc__', 'b1']
 >>>
 >>> globals()['b1']
<function b1 at 0x402e241c>


 >>> globals()
{'__builtins__': <module '__builtin__' (built-in)>, '__name__': 
'__main__', '__doc__': None, 'b1': <function b1 at 0x402e241c>}


I can't see what you can do with getattr here...
but :
 >>> len
<built-in function len>
 >>> getattr(__builtins__,"len")
<built-in function len>
 >>> getattr(__builtins__,"len") is len
True
