I would like to split a string using shlex (because I have to preserve text in quotes), but I do not want it to split over dots.

My code is the following:

import shlex
my_splitter = shlex.shlex('''foo, bar, "one, two", three four, 2.15''', posix=True)
my_splitter.whitespace += ','
my_splitter.whitespace_split = True
print(list(my_splitter))

output

['foo', 'bar', 'one, two', 'three', 'four', '2', '.', '15']

I do not want it to split '2.15' into '2','.','15'

Can you precise the command you use for splitting? – pylipp Mar 27 '19 at 10:52
it is `whitespace_split` – simona Mar 27 '19 at 10:54
Odd, I didn't think it would split like that. I would recommend trying the CSV parser instead as that look near enough to CSV. – Dan D. Mar 27 '19 at 10:55
See [Python 2 demo](https://rextester.com/FIQO15674), your code works. Same in [Python 3](https://ideone.com/PkIge4). – Wiktor Stribiżew Mar 27 '19 at 10:58
what is the csv parser? I have used numpy.gentotxt but it does not work because there are some items that have double quotes – simona Mar 27 '19 at 10:58
@WiktorStribiżew you are right, but it does not work on my system, I can't figure out why – simona Mar 27 '19 at 11:04

Use the CSV module as shown in the linked thread. – Wiktor Stribiżew Mar 27 '19 at 11:04
