Area of concentration on python, and where to stop

Hi everyone,

My name is Ebuka Umerah, an aspiring Data Engineer. i just started my journey and am a confused about the extent and area i might need to master in python. i don’t want to waste my time going off course and studying information that might be irrelevant to my ultimate goal, which is getting certified as a data Engineer by the end of this year.

i will be elated if i can be pointed in the right direction so i can optimize my time and concentration. thank you.
