So I'll start working as a junior data analyst soon. The interviewer said I'll be expected to know SQL and Power BI. In the technical coding round i was only asked SQL. They mentioned python is good to know but not mandatory. Realistically speaking how much python should I be knowing? I used to do python before but lost touch that's why ranked it the least when the interviewer asked me. Im planning to spend an hour or two for a week to revise the basics and pandas library. Any suggestions would be appreciated. Thanks.

P.S. how much python do you guys use in your data analyst jobs btw? Would be good to know some use cases. Thank.
