Format phonenumbers - regular expressions

[Viking]

Hi,

I am trying to format a list of phonenumbers.

I want to move through the list and do the same operation on each number, I have figured out how to do it one number at a time.

Would an option be to add a for loop?

import re

# List with phonenumbers
number = ['072 5674 323', "072 540 6789", "0047735 648975"]

# Remove spaces
num = re.sub(r'\D', "", number[0])

# Read backwards 
num_1 = num[-9:]

#Print country code + formated number 
print(F"0047{num_1}")

#Output
0047735674323

yes, or use list comprehension. And no need of regex too

numbers = ['072 5674 323', "072 540 6789", "0047735 648975"]
formated_numbers = [f"0047{number.replace(' ', '')[-9:]}" for number in numbers]
print(formated_numbers

Output:
['0047725674323', '0047725406789', '0047735648975']
