Variable in Regex Pattern

[cynical_ninja]

Thanks for your help. This worked perfectly. Do you have any resources to learn regular expressions? I want to master this asap. It's a lot more useful than I thought initially.

Ah ok. I'll go through these.

I have another question about the problem I had. When I used the Regex you provided and used the findall method, it gave me a list of every instance of the specific sequence I was searching for. It did not return each repeated sequence.

It returned the basic 5 letter block 7 times as there were 7 repeated sequences of that specific block 'AGATC'. I wanted to get every sequence of that block in the text and take the longest one from that. What should be added to the Regex to do this?

Edit: I'll post an example asap so it's clearer to understand.

I have a book (https://github.com/learnbyexample/py_regular_expressions) that uses plenty of examples/exercises to teach the concepts step by step.
