Regular expressions are useful for finding patterns in text and for enforcing standard patterns on text, very useful abilities for many programming tasks. Unfortunately, unless you already know how to use them then something like ^(?=.*[a-z])(?=.*[A-Z])(?=.*\d).{6,12}$ will look a lot more like a magic spell than a password validation test. Learning regular expressions does require some effort but fortunately there are new tools that streamline this process, doing a good portion of the work for you, and, perhaps, adding a little fun to puzzling them out.  In this hands-on workshop you'll get exposure to using regex101.com and ChatGPT as tools for reading and writing regular expressions. Our focus though will be on how you can use these tools to actually learn regular expressions—something that you still need to do despite the work these tools will do for you—so that in the near future you can use regular expressions with authority.
