Re: s.split() on multiple separators

Hello everyone,

OK, so I want to split a string c into words using several different
separators from a list (dels).

I can do this the following C-like way:

c=' abcde abc cba fdsa bcd '.split()
dels='ce '
for j in dels:
cp=[]
for i in xrange(0,len(c)-1):

The "-1" looks like a bug; remember in Python 'stop' bounds
are exclusive. The indexes of c are simply xrange(len(c)).

Python 2.3 and up offers: for (i, word) in enumerate(c):

cp.extend(c[i].split(j))
c=cp


c
['ab', 'd', '', 'ab', '', '']

The bug lost some words, such as 'fdsa'.


But. Surely there is a more Pythonic way to do this?

When string.split() doesn't quite cut it, try re.split(), or
maybe re.findall(). Is one of these what you want?

import re

c = ' abcde abc cba fdsa bcd '

print re.split('[ce ]', c)

print re.split('[ce ]+', c)

print re.findall('[^ce ]+', c)
