>>> import re

>>> a = 'this is a simple 3xampl3 of 2 or 3 numb3rs' # some text
>>> b = re.sub('\b[0-9]\b', 'xx', a)  # you need to use the r (raw) or else
it does work
>>> print b
this is a simple 3xampl3 of 2 or 3 numb3rs
>>> b = re.sub(r'\b[0-9]\b', 'xx', a) #replace with xx
>>> print b
this is a simple 3xampl3 of xx or xx numb3rs
>>> b = re.sub(r'\b[0-9]\b', '', a)  #replace with nothing
>>> print b
this is a simple 3xampl3 of  or  numb3rs
