All the Flow You'd Expect

Python v2 knows the usual control flow statements that other languages speak — if, for, while and range — with some of its own twists, of course.

More control flow tools

Python v2 is a programming language that lets you work quickly and integrate systems more effectively. »»> Learn More

Things people have built with Python v2 + PyHope — from a pure CPU framebuffer to an optional 9.4-million-pixel GPU render.

“One readable language can move from a browser idea to a desktop workspace, a game, a polished website, and a real Windows application.”

The CPU raycaster

A Wolfenstein-style renderer with original monster sprites, AI and a blaster. It flies past nine million computed pixels in under three seconds — play it.

▦

The Sudbury desktop app

Our own lightweight Launcher edits and runs Python v2, creates websites and games, previews projects, and opens the PyHope GPU lab. Get the app.

✓

Your profile, projects, and games—one template

The Playground’s portfolio studio turns editable Python v2 data into a polished personal website with live preview, exact HTML, project cards, and playable game links. Build yours.

»»>Get Started

Python v2 is free and open source. Run from source or use the installer to get the Sudbury desktop app, language, Windows EXE builder, and PyHope together. Full guides for VS Code, dev containers, desktop and any editor are on the Downloads page and in the documentation — then learn the language with the tutorial.

1. Grab the runtime

git clone https://github.com/gefrus112/pythonv2
cd pythonv2

2. Run something

python3 -m pyv2 examples/hello.pyv2

3. Or just talk to it

python3 -m pyv2
>>> print(f"{'2' * 3}")
222
Installation & editor setup

Your first program

# hello.pyv2
fn greet(name):
    if name == "":
        return "Hello, stranger!"
    end
    return f"Hello, {name}!"
end

for who in ["World", ""]:
    print(greet(who))
end

»»>Better. By Design.

Everything you loved about Python — plus the fixes the old one never shipped.

⏎

No More Indentation Wars

Blocks open with : and close with end. Tabs, spaces — do whatever. The compiler doesn't care. Your team won't either.

ƒ

Real Closures

Assignment finds the variable that already exists, wherever it lives. Counters that count. No nonlocal incantations required.

“”

F-Strings, Solved Forever

f"Hello, {name}!" — interpolation that just works, expressions and all. String concatenation with numbers is legal too.

!

Errors You Can Work With

Recover with try, inspect error.kind and error.message, and rely on finally for cleanup.

⚡

Runs In Your Browser

The same language runs in the terminal and on this very page — the playground is the real interpreter, not a screenshot.

♥

Two Implementations, One Truth

A Python reference runtime and a JavaScript twin, locked together by parity tests. Byte-identical output or the build fails.

»»> PyHope Sprite Raycaster

Start here with one of the arcade's four shooters. This level is drawn the hard way: a software raycaster computes every pixel on the CPU—but now it has original CC0 monster sprites, chasing AI, health, hit detection and a Comet Blaster. At 60 FPS it crosses nine million rendered pixels in 2.7 seconds. Want the GPU version? Visit the 9M GPU Lab.

– FPS MONSTERS 5 • KILLS 0 • HP 100 0 pixels rendered x 6.0 y 2.0

Learn step by step in the tutorial, explore the 50-topic field guide, or dig into installation in VS Code, dev containers / Codespaces, desktop and any code editor.

print(...)

Print any number of values, space-separated.

print("sum:", 1 + 2)

f-strings

Interpolate any expression with braces.

f"{name} scored {score * 2}"

fn / end

Functions are values. Closures capture properly.

fn add(a, b): return a + b end

if / elif / else

Blocks end with end, not a column number.

if x > 0: print("pos") end

while / break / continue

The usual loop verbs, no surprises.

while true: break end

for … in

Iterate lists, strings, maps and ranges.

for i in range(1, 10, 2): print(i) end

lists

[1, 2, 3] with methods that spark joy.

xs.push(4) xs.sort()

maps

Bare keys, dot access, safe get.

hero = {name: "Ada"} → hero.name

ternary

Condition first, like a question should be.

status = ok ? "yes" : "no"

try / catch / finally

Recover from runtime errors, inspect their fields, and always clean up.

try: risky() catch error: print(error.kind) end

builtins

len, range, sum, enumerate, zip, all, any, type, …

print(sum(range(5)))

string methods

upper, split, replace, trim, contains, slice, …

"a,b".split(",").join("-")

numbers

+ − * / // % **, floored mod, real division.

print(7 // 2, -7 % 3, 2 ** 10)
