[Tutor] Listing available variables

[Albert-Jan Roskam]

This may also be useful:

>>> a = 1
>>> b = 2
>>> c = 3
>>> locals()
{'a': 1, 'c': 3, 'b': 2, '__builtins__': <module '__builtin__' (built-in)>, '__name__': '__main__', '__doc__': None}
>>> locals().keys()
['a', 'c', 'b', '__builtins__', '__name__', '__doc__']
>>> 

Cheers!!

dir()

>>> a = range(10)
>>> b = 16
>>> c = ""
>>> z = ["this","that","none"]
>>> dir()
['__builtins__', '__doc__', '__name__', '__package__', 'a', 'b', 'c', 'z']
