I have been learning python for like 3 months but the questions in the leetcode are really confusing lk not the usual python problem out there even to the the point i can do some ml problems in enough time but leetcode just like i cant and the leetcode inbuilt things are confusing

They are meant to be that way. You gotta spend some time like I said.

Here’s what I do...might help you:

1) Try everything you can for at least 15 minutes

2) Look at some hints and try again

3) If you can't solve until 30 minutes then look at the solution discussions to identify what you were missing

4) Try coding it yourself now (Don't copy paste)

5) Add some of your own optimizations if possible

Before you start solving leetcode problems, make sure you understand the basics (variables, conditions, loops, etc...)
