With str.lstrip():
>>> '347 liverpool street'.lstrip('0123456789')
' liverpool street'
or, if you want to strip the space as well:
>>> '347 liverpool street'.lstrip('0123456789 ')
'liverpool street'
With a regular expression:
>>> import re
>>> re.sub('^[0-9]+', '', '347 liverpool street')
' liverpool street'
or
>>> re.sub('^[0-9 ]+', '', '347 liverpool street')
'liverpool street'
If you are doing this a lot my guess is that a compiled re will be faster but
that's just a guess...
