I was advised to learn the melt function also, is there any rules we should follow to know when to use it?

Interesting, you use the methid chaining syntax at the end for the mat variable. Where did you learn this practice? it is rare and I can discern a proficient coder by the use of this. are you US based?

The method chaining idea is inspired on the R dplyr package. Matt Harrison made it popular in pandas. I think it makes things easier in some cases but has it's downsides. I live in Argentina.
