Python language

LEGB

Name resolution order: Local, Enclosing, Global, Built-in.

Why interviewers ask about it

The consequence is what gets asked: assigning to a name anywhere in a function makes it local for the whole function, so reading it earlier raises UnboundLocalError rather than falling through to the global.

Closure

A function together with the enclosing scope it captured, keeping those variables alive after the outer call returns.
