How do I filter and transform a list in Python?

Asked 8 years ago · 142 votes · ✓ Top answer

You can use a list comprehension with a conditional clause:

# Get squared values of even numbers
numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
squared_evens = [n ** 2 for n in numbers if n % 2 == 0]
print(squared_evens)

Click the button → pick TypeScript →

// Get squared values of even numbers
const numbers: number[] = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
const squaredEvens: number[] = numbers
  .filter(n => n % 2 === 0)
  .map(n => n ** 2);

console.log(squaredEvens);

Built for the way you actually browse code.

No copy-paste, no juggling tabs, no dumping snippets into ChatGPT.

🎯

Detects every code block

Smart heuristic finds <pre>, <code>, GitHub .highlight, Medium, MDN, and any custom markup. Skips inline code & prose.

⚡

Auto language detection

80+ regex signals identify the source language with confidence scoring. Click the chip to override manually if you don't agree.

🔀

Diff view

Hit Ctrl+D to see exactly what changed line-by-line. No more squinting at two columns.

🔌

4 AI providers, your keys

OpenAI, OpenRouter, Groq, or Google Gemini. Switch providers or enter a newly released model ID at any time.

📜

History & cost tracking

The last 50 translations stay available in your popup. Per-provider token and cost estimates keep usage visible.

🛡️

Offline rules included

Common refactors (jQuery → Vanilla JS, ES Modules ↔ CommonJS, Promises → async/await) work without any API call. No key required.

🌑

Auto dark mode

Panel UI follows your OS theme. Both source & output are syntax-highlighted in light or dark. Shadow DOM means host-page CSS can never break it.

🧹

Smart sanitizer

Strips line numbers, shell prompts, and zero-width chars before sending so the AI doesn't waste tokens decoding the cruft you copied.

⌨️

Keyboard-first

Ctrl+↵ translate · Ctrl+D diff · Ctrl+L chain · Esc close.

Three steps. Twenty seconds.

Install & pick a provider

Add to Chrome, then enter your OpenAI, OpenRouter, Groq, or Gemini key. Provider pricing and free tiers are set by each provider.

Browse like normal

Hover any code block on Stack Overflow, MDN, GitHub, Medium, your team docs — a small ↻ Shift button appears.

Click & copy

Pick your target, hit Translate. Highlighted, diffable, and ready to paste into your editor.

FAQ

Is my code sent to a server you control? ▾

No. Code goes directly to your selected provider, or up to three configured providers when you choose Compare. Connection tests send a ping and API key. SnippetShift has no backend, analytics, or request logging.

How accurate are the translations? ▾

Accuracy depends on the provider, model, source, and target. Review and test generated code before use. Offline conversions cover limited syntax-checked patterns; complex transformations require AI. The panel includes a diff view to support review.

Do I have to pay anything to start? ▾

The launch build has no extension fee. Provider API pricing is separate and may change. Built-in offline rules and cached results require no provider request.

Will my API key leak? ▾

Starting with v0.3.2, saved keys are encrypted with AES-256-GCM using a non-exportable key stored by the extension. They never appear in page DOM and are sent only as authentication data to the provider you chose. Encryption cannot protect a compromised browser profile or device. Keys are never sent to SnippetShift because SnippetShift has no server.

Which sites does it work on? ▾

Ordinary web pages with recognizable <pre> code blocks are supported. You can also select code or use the popup. Browser internal pages, the Chrome Web Store, inaccessible frames, and some custom editors restrict injection. Site layouts can change; compatibility is not guaranteed for every website.

Open source? ▾

Yes — MIT license. The source repository URL will be published with the Chrome Web Store release.
