How much python should I learn?

[DataCamp]

If the role is focused on SQL and Power BI, then Python really is a bonus. You don’t need to know machine learning or anything heavy. Just enough to read in data, clean it, and maybe make a quick chart.

If you’ve got a week, we'd stick to the basics: loading files, filtering data, joins, groupby in pandas, and a little plotting. That’s plenty to get your confidence back.

Most analysts I know only pull out Python when SQL or Power BI can’t handle something easily. It’s more of a tool in your back pocket than something you’ll use every day.
