You don't need to use eval. You could just extract the numeric part and
turn that into an integer, for example using regular expressions:

import re

s = "name123"
pattern = re.compile("name([0-9]+)") # Pedants go bother someone else ;-)
match = re.search(pattern, s)
if match:
    print "Your number is %d" % int(match.group(1))

Yes, there is. Max M wrote it in another message (and a nice solution it is too,
Max). That's probably the way to go.

Best of luck.
