I believe this question to be rather variable in its answer. If all
your strings are of the form "### word word", then you could safetly
use 'split', as in:

>>> s = '347 liverpool street'

def splitter(s):
    l = s.split()
    try:
        i = int(l[0])
        return i
    except ValueError:
        print "String segment not a number"

>>> splitter(s)
347

But, if your string is also of the form "347-10 liverpool street",
then your problem is more complex.
