I've been trying to match with regex all alphanumeric characters, except for the underscore.
I'm currently using r"^[a-zA-Z0-9]*", but I wondered if it was possible to use \w and exclude _.
Thanks!

Python has a special sequence \w for matching alphanumeric and underscore. Please note that this regex will return true in case if string has alphanumeric and underscore.
The _ (underscore) character in the regular expression means that the zone name must have an underscore immediately following the alphanumeric string matched by the preceding brackets. The . (period) matches any character (a wildcard).
For checking if a string consists only of alphanumerics using module regular expression or regex, we can call the re. match(regex, string) using the regex: "^[a-zA-Z0-9]+$".
Yes, like that: [^\W_]
Where \W is the opposite of \w
