Why cannot jump out the loop?

[Mark McEahern]

Sorry for top-posting:  I just wanted to add that in the OP's case, what 
he really needs is for not while.

import sys
n = int(sys.argv[1])
for i in range(n):
    print locals()

// m

p.s.  Others have already noted that sys.argv returns a sequence of strings.
