The video tutorial covers the concept of sets, highlighting their properties such as unordered and distinct elements. It contrasts sets with ordered collections and poses a question about their properties. The tutorial then introduces two Python practice problems: one to determine if a list of sets forms a partition of a parent set, and another to verify set identities through code. The exercises involve writing functions and testing them with random sets to understand set operations better.
