Python Phone Number Pattern Matching w/ RegEx (findall)-CodePudding

I need to match to a NANP standard 10-digit phone number with some using – as a separator (e.g. 123-456-7890) and some will have a dot (.) as a separator (e.g. 123.456.7890).

I have tried:

numbers = "123-456-7890, 123.456.7890"
phones = re.findall("\d{3}*\D*\d{3}*\D*\d{4}", numbers)

CodePudding user response：

Try this:

import re
result = re.findall('\d{3}[-.]\d{3}[-.]\d{4}', numbers)
print(result)

Output: ['123-456-7890', '123.456.7890']

[-.] : match only - or .
\d{3} : three times match any digit (0-9)
