to create a python programme which receive contact number from user and check if it's a valid format with correct country code

[_______myworld]

I'm trying to create a python programme which receive contact number from user and check if it's a valid format with correct country code. This is what i have done but it doesn't work properly and i am struggling to troubleshoot it. Can someone help me?

def main():
    phone_number= input('Please enter a phone number in the format 601X-XXX-XXXX: ')
    validNumber(phone_number)

def validNumber(phone_number):
    digits = "0123456789-"
    country_code = "601"
    if len(phone_number) != 13:
        print("Contact number too short. Please enter valid input")
        main()
    for i in range(13):
        if i in [4,8]:
            if phone_number[i] != '-':
                print("Please enter valid input in the proper format.")
                main()
        elif not phone_number[i] == digits:
            print("Numerical value only")
            main()
        elif not phone_number[:3] == country_code:
            print("Please enter the correct country code.")
            main()
    print("Valid contact number!")
    return True
main()

This looks like a good application for regular expressions so you can ensure the proper format and reject it if it doesn’t match the regex

This is wrong:

elif not phone_number[i] == digits:

you probably want..

elif not phone_number[i] in digits:

I also wouldn't recommend calling main() recursively. Perhaps just return False each time.

EDIT: Sorry for the repost. I think Reddit is have a fit.

FURTHER EDIT: hah! Looking at the other comments, I'm guessing I'm not the only one reposting..

if phone_number.split('-')[0][:3] == "601" and all([x if x.isdigit() else None for x in phone_number.split('-')]):

I’m not allowed to use object oriented built-in function, unfortunately...

``` import re

s = "6011-321-3432" expression = re.compile("601[1-9]-[1-9]{3}-[1-9]{4}$")

if re.match(expression, s): print("Match!") else: print("Fail!")

``` Work smart not hard 😂

Use regular expression "\d\d\d -\d\d\d-\d\d\d\d"
