What's inside

  • Every Python idea as a one line mental model with a runnable example
  • Hand drawn diagrams for the parts that trip people up
  • A gotcha on every page, the classic mistakes caught early
  • A tight cheat sheet you can keep open while you code

What's covered

  1. 0 · Orientation how Python runs
  2. 1 · Fundamentals types, operators, truthiness
  3. 2 · Control flow & functions Indentation IS the block, a colon opens it, the indent level is its body.
  4. 3 · Data structures An ordered sequence, a list you can edit, a tuple you can't.
  5. 4 · Strings & files A str is an immutable sequence of characters, every "edit" returns a brand-new string.
  6. 5 · OOP classes & objects
  7. 6 · Iterators & generators An iterable can be asked for a fresh iterator ; the iterator hands out one value at a time.
  8. 7 · Errors & modules An error propagates through the call stack until a matching except catches it, or it crashes the program.
  9. 8 · Pythonic toolkit A decorator wraps a function in another function, adding behaviour without touching its body.
  10. 9 · Cheat sheet & gotchas

Python in One Week compresses the whole Python language into a tight little booklet you can finish in a weekend. Every concept comes with one mental model, one runnable example, a picture when a picture helps, and the one gotcha that trips everyone up.

This book respects your time. No filler and no padding, just the parts that matter, in a handwritten style that is genuinely nice to read.
