The [] indicate the last two parts are optional. If you don't supply them, exec
just uses the current namespace.
However, as others have said, you are much better off using a separate
dictionary for such values, rather than stuffing them into the local variables:
user_vars = {}
y = "a"
user_vars[y] = 4
It keeps a clean separation between your variables and the user's variables,
easily avoiding namespace conflicts.
Cheers,
Nick.
