If you need to detect syntax issues, you can use `re.compile()`. For example, before Python 3.11, you'll get an error: >>> re.compile(r'\w++') re.error

If you need to detect syntax issues, you can use `re.compile()`. For example, before Python 3.11, you'll get an error: >>> re.compile(r'\w++') re.error: multiple repeat at position 3 To use such a compiled pattern, you can call the method on this object instead of `re`. For example: >>> word = re.compile(r'\w+') >>> word.findall('hello-there!') ['hello', 'there']
