Python in One Week
The whole language in a weekend of crash notes
What's inside
- Every Python concept as a one-line mental model + one runnable example
- Hand-drawn diagrams for the ideas that trip people up
- A gotcha per page — the classic mistakes, pre-empted
- A condensed cheat-sheet you can keep open while you code
What's covered
- 0 · Orientation how Python runs
- 1 · Fundamentals types, operators, truthiness
- 2 · Control flow & functions Indentation IS the block — a colon opens it, the indent level is its body.
- 3 · Data structures An ordered sequence — a list you can edit, a tuple you can't.
- 4 · Strings & files A str is an immutable sequence of characters — every "edit" returns a brand-new string.
- 5 · OOP classes & objects
- 6 · Iterators & generators An iterable can be asked for a fresh iterator ; the iterator hands out one value at a time.
- 7 · Errors & modules An error propagates through the call stack until a matching except catches it — or it crashes the program.
- 8 · Pythonic toolkit A decorator wraps a function in another function — adding behaviour without touching its body.
- 9 · Cheat sheet & gotchas
Python in One Week compresses the entire Python language into a tight, diagram-first booklet you can finish in a weekend. It’s built on the “cram-4” method: for every concept you get one mental model, one canonical runnable example, a picture when a picture beats prose, and the one gotcha that trips everyone up.
Python is the lingua franca of data & scripting, and this book respects your time: no filler, no padding, just the parts that matter — in a handwritten style that’s genuinely enjoyable to read.
