Is this what you want? import shlex lText = "This is a 'short string' for you to read." lWords = shlex.split(lText) print lWords produces, ['This', 'is', 'a', 'short string', 'for', 'you', 'to', 'read.'] Shlex can be found under 'Program Frameworks' under 'The Python Standard Library' of ActivePython 2.7 documentation.

If that's your desire, python has a module in the standard library that will help, called shlex (http://docs.python.org/library/shlex.html). Particularly, shlex.split may do exactly what you want out of the box: Python 2.6.4 (r264:75708, Oct 26 2009, 08:23:19) [MSC v.1500 32 bit (Intel)] on win32 >>> import shlex >>> s = "This is an 'example string'" >>> shlex.split(s) ['This', 'is', 'an', 'example string'] >>> -- Jerry -- http://mail.python.org/mailman/listinfo/python-list

You can use a list comprehension:
l2 = [x.rsplit(...) for x in l]
But for the original question, maybe the csv module would be
more useful: you can change delimiters and quotechars to match
your input:
import csv
reader = csv.reader(open("foo.txt", "rb"), delimiter=' ', quotechar="'")
for row in reader:
print row

Here's a way:
>>> s = "This is an 'example string' with 'quotes again'"
>>> [x for i, p in enumerate(s.split("'")) for x in ([p] if i%2 else p.split())]
['This', 'is', 'an', 'example string', 'with', 'quotes again']

Hi Everyone, Can we use rsplit function on an array or vector of strings ? it works for one not for vector Alemu -Original Message- From: python-list-bounces+atadesse=sunedison@python.org [mailto:python-list-bounces+atadesse=sunedison@python.org] On Behalf Of Massi Sent: Wednesday, November 23, 2011 10:10 AM To: python-list@python.org Subject: String splitting by spaces question Hi everyone, I have to parse a string and splitting it by spaces.

String splitting by spaces question
Hi everyone, I have to parse a string and splitting it by spaces. The problem is that the string can include substrings comprises by quotations which must mantain the spaces. What I need is to pass from a string like: This is an 'example string' to the following vector: ["This", "is", "an", "example string"] Which is the best way to achieve this?
