SEE WHAT PYTHON DOES WHEN IT RUNS YOUR CODE
A visual study guide to the Python essentials on two sheets, printed on both sides. Instead of a list of syntax rules, it shows what Python actually does with each line: which line runs next, what each name refers to, and what comes back from a function. One small program (adding up prices) runs through the whole sheet: traced step by step, looped, and finally turned into a function, so you learn the example once and follow it everywhere. Every code example shows its real result.

SHEET 1, FRONT - HOW PYTHON RUNS A PROGRAM
- watch a program run: a 6-line program traced in 12 steps (line, values, output)
- evaluate, then bind: the right side of = runs first, then the name is bound
- same-looking assignment, different result: rebinding an int vs changing a list
- == vs is: same value or same object?

SHEET 1, BACK - TYPES, OPERATORS & TRUTHINESS
- int, float, str, bool and None as cards, with conversions (and what fails)
- / always gives a float; //, % and ** explained
- a precedence tree: which operator runs first
- why 0.1 + 0.2 == 0.3 is False
- what counts as False? the full table, and what "and" / "or" really return

SHEET 2, FRONT - CONTROL FLOW
- if / elif / else, for and while drawn as flowcharts next to the code
- indentation is the block: print inside vs after the loop
- range (the stop is never included), break and continue traced
- how many times does the loop body run? enumerate and zip

SHEET 2, BACK - FUNCTIONS & SCOPE
- what happens when you call a function, drawn: arguments, a new local scope, the return value
- positional, keyword and default arguments
- print vs return: a function without return gives None
- scope: where does a name come from? (local, enclosing, global, built-in)
- trap cards: UnboundLocalError and the mutable default argument

Common beginner mistakes are on small warning cards next to the topic they belong to (typos and NameError, "3" + 4, if x == 1 or 2, changing a list while looping, off by one, = vs ==, and more).

TEST YOURSELF VERSION
The same pages with the answers left blank: predict the output, fill in the trace and the results. Fill them in from memory, then check yourself against the cheat sheet.

WHAT YOU GET: 8 PDF FILES (in one ZIP)
- Cheat Sheet and Test Yourself
- 2 colour styles: Color, and Gray (uses less coloured ink)
- 2 paper sizes: A4 and US Letter
- each file is two sheets: 4 pages, print double-sided ("flip on long edge")
- a short READ ME with printing tips

WHO IT IS FOR
Beginners who have written a few lines of Python but want to understand what is going on; students in a first programming course; self-taught learners and career changers; people moving to Python from another language; anyone starting a data science or data analysis course.

HOW IT IS MADE
Typeset in LaTeX; every diagram is drawn by code, no AI image generator was used. The content and the code were prepared with help from an AI assistant. Every code example on the sheet was run by a script in Python 3.12 and its result checked, and the content went through several independent reviews.

HOW IT WORKS
1. Purchase the listing.
2. Download the ZIP file instantly from Purchases & Reviews in your Etsy account (or from the link in your confirmation email) and unzip it.
3. Print at home or at a print shop at 100% / "actual size", double-sided, or open the PDF on a tablet.
