Python :)

awesome

pick something that is lowlevel so that you are in controll of everything. C.

Bash script and phyton

C, python, powershell

Honestly it just depends on what you're doing. For malware, definitely C; for quick scripts; either python, ruby, javascript, or go; for reverse engineering and exploit development; assembly. I also highly recommend learning SQL.

You master the algorithm is all what you need man

C is good to know as it helps you with understanding disassembly

Python is a good language, powerful and easy to learn

Python best of the best

my first choice would be bash for small scripts and python/ruby for more advance coding...
