Regex to extract phone number in complex text

Question

I spent a lot of time to write a regex to match the following strings:

tel/mob: 001 433 123 4352
tel/mob: 0014331234352
tel: 001 433 123 4352
tel: 0014331234352
tel/mob: 001 (433) 123 4352
tel: 001 (433) 123 4352
tel/mob: +1 433 123 4352
tel/mob: +14331234352
tel: +1 433 123 4352
tel: +14331234352
tel/mob: +1 (433) 123 4352
tel: +1 (433) 123 4352

What I did is:

print (re.findall(r':\s(\w+)' , article))

But it does not work properly, I need to extract numbers.

Could you show us fragment of the file? Are the numbers in separate lines or somewhere in the text? — h4z3, Dec 30 '19 at 10:49
@h4z3 sometimes in separate lines and sometimes they are somewhere in the text — Mahdi, Dec 30 '19 at 10:50
Is the problem just the +? testing your regex the only issue on this data is the plus. If you have other issues please post text example to illustrate. — Neil, Dec 30 '19 at 10:55
`r'(tel|mob): (\+|00)([ \(\)]*\d){11}'` - gets `tel:`/`mob:`, then `+`/`00`, then 11 following digits, with spaces, `(` and `)` in any place. Works for all presented cases. — h4z3, Dec 30 '19 at 10:56

I've allowed an optional + sign at the start, and repeating groups of numbers, and optional parenthesis. Works on supplied examples.

r':\s\+?(\(?[0-9]+\)?\s?)+'

it does not contain strings that have spaces within, like 001 433 123 4352 – Mahdi Dec 30 '19 at 11:09
what do you mean? – Neil Dec 30 '19 at 11:27
For example, for a number like 001 4331234352 it just matches 43312344352 and 001 is not match – Mahdi Dec 30 '19 at 11:32
@Mahdi first, it does match 001 43312352. Check in the link. Second, if you are going to ask a question about regexes you must put all the examples you want to match. I can't guess what else is in your data. – Neil Dec 30 '19 at 14:24

What about taking everything after the :, that is ether a digit, space, plus or bracket ?

import re

data = """tel/mob: 001 433 123 4352
tel/mob: 0014331234352
tel: 001 433 123 4352
tel: 0014331234352
tel/mob: 001 (433) 123 4352
tel: 001 (433) 123 4352
tel/mob: +1 433 123 4352
tel/mob: +14331234352
tel: +1 433 123 4352
tel: +14331234352
tel/mob: +1 (433) 123 4352
tel: +1 (433) 123 4352"""

for line in data.splitlines():
    m = re.search(r':([0-9() +]+)', line)
    print ''.join(c for c in m.groups()[0] if c.isdigit())

Output:

0014331234352
0014331234352
0014331234352
0014331234352
0014331234352
0014331234352
14331234352
14331234352
14331234352
14331234352
14331234352
14331234352
