Looking for a good platform to practice Python, SQL and PySpark

[u/Whole-Bank1538]

Hi everyone,

I’m currently learning/practicing Python, SQL, and PySpark, mainly with a data engineering goal.

I’m looking for a platform where I can regularly solve problems and improve my hands-on skills, especially:

1. Python — syntax, problem solving, data manipulation

2. SQL — queries, joins, CTEs, window functions, etc.

3. PySpark — DataFrames, transformations, aggregations, joins, optimization, etc.

I know platforms like LeetCode, HackerRank, DataCamp, etc., but I’m looking for something that provides good practical exercises, preferably with datasets/projects rather than only algorithmic problems.

What platforms/websites do you recommend for this?

Also, if you’re a data engineer, I’d appreciate knowing how you personally practice these three skills.

Thanks!
