My friend works in a bank and for a long time has wanted to make the switch to Python. To date, he has read a few books and knows some intermediate concepts, such as closures, generators, etc.. Outside of Python, he has built workflows in Alteryx and knows some SQL.His teenage son challenged him to start applying for roles in 3 calendar months from now. He figures he can dedicate a max of 3 hours per day. How should he best use his time?Should he drill on Leetcode? Build a small portfolio? Gain a specialization within Python? How best would you allocate his hours?
