Roadblock in SoloLearn challenges

Question

I can get through the easy challenges fairly easy now using if else statements, but I barely have an idea of what to do for the medium challenges. What would you guys recommend for digging into a bit more. I’ve gone through the Python course but what other modules, or actions on Python should I look a bit more into?

Answer 1

Regular Expression is used in some medium level codes

Answer 2

Learn to use lists, dictionaries. Also learn the split(), replace(), join() methods. These are very useful in string handling. Also learn the string indexing tricks like the one in this code:

P.S: I don't know regular expressions yet but I have completed all the free code coach challenges in python.
