Hello @T_Willins 

 

That must have been a pretty good class on web scrapping; the only thing that I don't undersand much is the use of two REGEX operators on the Ingredients group (.*?)

 

The asterisk operator should match the preceeding character zero or more times, and the ? operator should match it zero or one time. I am a little confused on the purpose of the ? operator following the asterisk. It seems that with or without it pulls the same results. Is there any strategy behind it?

Hi @JORGE4900.  I used the (.*?) as habit as I have had too many times when my wildcard .* returned to long of a string.  In this specific data set it is not needed and (.*) would return the same results.  Adding the ? makes the operator non-greedy.  There is a great page on Perl Syntax at:

If you get a chance to take the webscraping (or any other pre-conference classes) at #Inspire I would strongly recommend them.

Hi @NicoleJohnson 

 

I really enjoyed looking at your application. Very nice job, and I have to say Frozen Strawberry Daiquiris sound pretty good for a sunny day.

My first challenge. Not a bad way to learn about how to work in the designer.
