It should work. Did you forget to
import __main__
before trying?

The answer to all your questions is dir() for names and vars() for the
complete namespace dictionary:
>>> x = 42
>>> dir()
['__builtins__', '__doc__', '__name__', '__package__', 'x']
>>> import os
>>> dir(os)[:5]
['EX_CANTCREAT', 'EX_CONFIG', 'EX_DATAERR', 'EX_IOERR', 'EX_NOHOST']
>>> vars()
{'__builtins__': <module '__builtin__' (built-in)>, '__package__': None,
'x': 42, '__name__': '__main__', 'os': <module 'os' from
'/usr/lib/python2.6/os.pyc'>, '__doc__': None}
