TLDR:

Pylance (Microsoft's Python extension for VS Code) now officially supports using Meta's Pyrefly to power its analysis.

To enable this, Microsoft developed an extension to the language server protocol (LSP) called the type server protocol (TSP), a new standard that separates wider set of language server features from the type checker/compiler powering some of them.

0 Upvotes

hello!

I am a data science student, have been coding 2 years.

I recently use AI to code python, or checking codes people already made or teacher gives us assingment.

but is it really helpful to learn how to code do you think?

i check every single code if i got assingment by asking AI to explain that.

it doesnt feel i study something so i worry about that i really study.

can you guys give me some tips ?
