Exec with loops

Is it possible to use exec to run code that includes a loop? For example:
a='for b in range(4):\n print b' exec a This fails with a syntax error. It
also fails if I do this: exec 'for b in range(4):' exec ' print b' But this
works: exec 'for b in range(4): print b' But this limits you to simple loops
and prevents nested loops (and if statements). Anybody know how to use exec
to run code containing arbitrarily complex loops? Thanks.
