Use regular expressions!
A nice Python introduction:
  http://py-howto.sourceforge.net/regex/regex.html

Here is some sample code that parses a line of user input.

# -------------------------------------------------
import re

print "Please type a number, then a word.  Like this:"
print "> 1884384 toad"
print

x = raw_input('> ')
match = re.match(r'^\s*(\d+)\s+(\w+)\s*$', x)
if match is None:
    print "Sorry, I couldn't parse that."
else:
    number, word = match.groups()
    print "Your number was:", number
    print "Your word was:", word
