Thanks! Great article. Now the code looks like this:

---
import sys

def prompt():
   return raw_input("Put a digit here: ")

try:
   a = prompt()
   while 1:
      a = a.replace(' ','')
      if a[0] == '-' and a[1:].isdigit():
         a = int(a)
         break
      elif not a.isdigit():
         a = prompt()
      else:
         a = int(a)
         break
except:
   print sys.exc_info()[1]
   sys.exit()
---

...and it's not too bad example of reliable code getting input from users ;)
