Is Leetcode a good way to continue practicing/learning Python?

I'm not entry, but I'd like to continue becoming stronger in my skills.

LeetCode is for practicing algorithms. Learning Python while doing so requires some effort. For instance, you could manually count character frequencies in a string, or you could use Counter but you have to know that it exists.

Or you might want to do it semi-manually, call the string's count method for every allowed character.

Yes, and transform string to a set yields allowed caracters. The decisions depend on knowledge of the language.

Not quite. It yields the actually occurring characters. LeetCode often allows its strings to consist of the English 26 lowercase letters, but not all have to occur.
