How long does it take to become a master coder

Answer 1

I think your rest of life is indeed less to become a master coder😅
Anyways,it makes sense as to master any language, you've to keep learning and practising as it's too vast and there's always some new syntax/attribute arriving in new versions until you complete the old.
Also,In my dictionary master coder is the one who knows more than 100 languages deeply;And Python is just one of them; Try to master Python if you can😎

Answer 2

more or less: it almost depend of a lot of things (actual background, time to learn and practice, area of coding, own capacities...)

Answer 3

approximately 5628hrs
