import string

text =3D '1string'
if text[0] in string.digits:
    print "text's first character is a number"
else:
    print "or it is something else ...."

there is also the regex approach:

import re
text =3D '1string'
num_re =3D re.compile(r'^\d+')
if num_re.search(text):
    print "text begins with a number"
