Python Medium Theory

Common Python comparison topics: set vs list, append vs extend, remove vs pop vs del, sort() vs sorted(), @staticmethod vs @classmethod, and generator vs iterator

Interview prep often comes down to comparing similar tools and explaining when each one is the better fit.

  • Lists preserve order, sets optimize membership
  • append adds one item while extend adds many
  • sorted returns a new list while sort mutates in place

  • Many pairs differ by ownership, timing, or performance
  • Use cases matter more than memorized slogans

React Hard Theory

React coding-adjacent design questions

Many React interviews ask you to reason about UI architecture problems such as search boxes, large lists, debounced input, reusable forms, caching, modal state, theme switching, and optimistic updates.

  • Think in data flow, state ownership, and rendering costs
  • Reuse logic with hooks or composition
  • Separate server state, UI state, and transient interaction state
