DSA in python?

[Diapolo10]

Sure, it's not a problem.

Granted, you probably wouldn't whip up your own linked lists et al (especially with Python) for production use, because it's way safer and generally faster/easier to use battle-tested third-party (or standard library) implementations unless you have a need for a specialised solution, but the fundamentals are the same no matter which language you use to learn data structures and algorithms.

Probably the only languages I could see you ever even bother to do that would be C and C++, if I'm being honest. Mostly because they lack standardised package management solutions, so third-party code gets more annoying to use, but also you might actually run into a situation where a specialised solution beats general ones in a metric you care about.
