Regular Expression using Python

Question

Please help me fix this regular expression check.

x=re.match('^(\d{3})\s\d{3}-\d{4}$','(800) 325-3535')

It is supposed to return match object but what I get is None value. Am I doing anything wrong over here. Please help.

Answer 1

You should escape the () by backslash:

^\(\d{3}\)\s\d{3}-\d{4}$

Like this:

x = re.match('^\(\d{3}\)\s\d{3}-\d{4}$','(800) 325-3535')

() means capturing groups in regex and whatever symbol has a special meaning in regex should be escaped to be used in its literal form.
