Doesn't work inside a function:

>>> def parrot():
...     for name in ['A', 'B', 'C']:
...             vars()[name] = ord(name)
...     print vars()
...     print A
...
>>> parrot()
{'A': 65, 'C': 67, 'B': 66, 'name': 'C'}
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 5, in parrot
NameError: global name 'A' is not defined
