Normalize Phone Numbers Using Python

I am extremely new to python. I often get text files that have phone numbers is various formats. I am trying to create a python script that takes this text file and normalizes them

Solution 1:

This might help you:

import re

withopen('test_numbers.txt') as f:
    dirty = f.readlines()

clean = []
for l in dirty:
    clean.apped('+1{},\n'.format(re.sub(r'[^0-9]', '', l)))

clean will be a list of lines with +1 at the beginning and , at the end. You may then save it to a text file with:

withopen('formatted_numbers.txt', 'w') as f:
    f.writelines(clean)

You can also use a one liner using list comprehension:

clean = ['+1{},\n'.format(re.sub(r'[^0-9]', '', l)) for l in dirty]
