How can I remove several unwanted characters from phone number strings using Code by Zapier?

Need a script to delete ‘+’, ‘-’ and spaces from phone number strings in Code by Zapier. For example:

import re
input_val = '+1 305-267-2700'
cleaned = re.sub(r'[+\-\s]', '', input_val)
print(cleaned)

I have dealt with this exact situation and found that determining the unwanted characters in a comprehensive regex saves a lot of headache later on when cleaning up multiple phone formats. I typically build the regex pattern dynamically as my needs evolve; this sometimes means adding extra symbols if the data source changes. In my implementation, I first verified the output with a few test cases to ensure that no extra digits were removed. The approach using Python’s re module worked smoothly and kept the code clear and maintainable.
