5,649 PointsNo offense, Kenneth, but this is not good instruction.
These videos need to be updated. Please break it down further. The instructor needs to isolate the variables more. I find myself having no idea how or why these regular expressions are working. I would suggest starting with a much simpler .txt file and going through the instructions with much more explicit explanation. For example, what do the $ and ^ do? Show examples of changing one thing at a time instead of writing a whole line of code then saying "look it worked, that's neat". Please explain why it worked!
Sorry for the rambling, but this is frustrating.

11,835 Pointsregexr.com is a useful tool to break down regex and use it in a sandbox.
^ and $ could mark the beginning and the end of a search pattern, by the way.

5,649 PointsThanks Zimri. That website is definitely useful.
I still don't understand what ^ and $ mean really but I'm sure I'll figure it out at some point.

You can choose Python as the programming flavor. Just fiddling around with these sandboxes turned out to be the key for me understanding all of this. Thanks again, Zimri.

Should we select JavaScript RegExp or PCRE via PHP if we're learning Python? Probably PCRE since it's server side and closer to PERL?
