Regex input 1 ,2 ,3 into list

Question

Hello guys I'm trying to split this string

"1, 2, 3 , 4 , 5, 6,7"

into this array

['1','2','3','4','5','6','7']

And get an error if there are characters or multiple spaces (one white space is acceptable following or before a comma)

I'm doing

re.split(r'\s?,\s?', some_string)

but this does not return an error for invalid matches such as (",," or ", ,"). How could I accomplish that ?

Use `re.findall(r'\d+', s)` – Wiktor Stribiżew Apr 24 '18 at 14:23 — Wiktor Stribiżew, Apr 24 '18 at 14:23

You don't necessarily need a regex for this

>>> s = "1, 2, 3 , 4 , 5, 6,7"
>>> [i.strip() for i in s.split(',')]
['1', '2', '3', '4', '5', '6', '7']

But that leaves the spaces near the commas if they exist – Bruno Lopes Apr 25 '18 at 17:24
