This looks good to me @Agent-Hellboy! Thank you so much for the contributions! Can you add some tests for the istitile() and isalpha() on compile time strings? (I think the tests refactored in this PR are for runtime strings.)

Hi @Shaikh-Ubaid, I didn't understand much, so the test added in test_str_attribute is for execution happening at asr, I guess that's compile time, for runtime where do I need to add those tests?

@Agent-Hellboy What is the status of this PR? Resolve the conflicts and reviews. After that mark it as Ready for review.

We can add both compile time and run time in the same test. Example:

"abc".istitle() # compile time
s: str = "abc"
s.istitle() # runtime

I think @Shaikh-Ubaid suggested to keep the test removed from test_str_01.py
