What's the best way to format a phone number in Python?

Question

If all I have is a string of 10 or more digits, how can I format this as a phone number?

Some trivial examples:

555-5555 555-555-5555 1-800-555-5555 

I know those aren't the only ways to format them, and it's very likely I'll leave things out if I do it myself. Is there a python library or a standard way of formatting phone numbers?

Answer 1

Seems like your examples formatted with three digits groups except last, you can write a simple function, uses thousand seperator and adds last digit:

>>> def phone_format(n):                                                                                                                                   ...     return format(int(n[:-1]), ",").replace(",", "-") + n[-1]                                                                                                            ...  >>> phone_format("5555555") '555-5555' >>> phone_format("5555555") '555-5555' >>> phone_format("5555555555") '555-555-5555' >>> phone_format("18005555555") '1-800-555-5555' 

Answer 2

for library: phonenumbers (pypi, source)

Python version of Google's common library for parsing, formatting, storing and validating international phone numbers.

The readme is insufficient, but I found the code well documented.
