Not really a Django question, just basic Python. For starters strip() will remove only leading and trailing chars in the set, not embedded chars.
Curiously though, with all due respect, this: if dataless.isdigit() != True: has beginner written all over it. What's wrong with: if not dataless.isdigit(): Comparing booleans by value is an interesting notion. But personally, Django is rooted on the principle of DRY (Don't Repeat Yourself) and if I wanted to store phone numbers I'd look to see who's done it already and lo and behold django-phonenumber-field <https://github.com/stefanfoulis/django-phonenumber-field>! https://github.com/stefanfoulis/django-phonenumber-field Try that maybe and save yourself a lot of thinking and hassle on the phone number formats.
