google-translate-unofficial (Python)

Unofficial Google Translate for Python - no API key required.

Installation

pip3 install --upgrade google-translate-unofficial

Usage

from google_translate_unofficial import translate, translate_batch, get_languages

Translate a string

from google_translate_unofficial import translate

translate("Hello world", target="es")
# "Hola mundo"

translate("Bonjour", target="en", source="fr")
# "Hello"

translate("こんにちは", target="de")
# "Hallo"

The source parameter defaults to "auto", letting Google detect the language automatically. Languages can be passed as full names or ISO codes interchangeably.

translate("Hello", target="spanish")
translate("Hello", target="es")
# both return "Hola"

Translate a batch

from google_translate_unofficial import translate_batch

translate_batch(["cat", "dog", "house"], target="fr")
# ["chat", "chien", "maison"]

Get supported languages

from google_translate_unofficial import get_languages

get_languages()
# ["afrikaans", "albanian", "amharic", ...]

get_languages(as_dict=True)
# {"afrikaans": "af", "albanian": "sq", "amharic": "am", ...}

Notes

• The maximum safe input length is around 5000 characters per call.
• If you translate large batches in a tight loop you may hit rate limits. Add a small delay between calls if needed.
