It of course works, but there's a large amount of situations to think of.

import sys
try:
   while 1:
      a = raw_input("Put a digit here: ")
      if not a.isdigit():
         a = raw_input("Put a digit here: ")
      else:
         a = int(a)
         break
except:
   print sys.exc_info()[1]
   sys.exit()

print a

Any ideas to make it more reliable ?
