I noticed that the translation functions accepting source/target languages do so with a `str` type hint. Would be nice to have a `Literal[\"EN\", \"FR\", ...]` in order to get IDE completions like these:\n\nhttps://github.com/user-attachments/assets/36c2f40d-bfd3-4764-ae95-1ab6e51d8538\n\nThis could be as simple as adding something like:\n```python\nfrom typing import Literal\n\ntype LanguageLiteral = Literal[\"en-gb\", \"en-us\", \"fr\"] # + all other supported languages\n```\nThis could then be added as a type hint to `translate_text` and the like for better IDE support. I would be happy to submit a PR if this is something you guys would like to have!","author":{"url":"https://github.com/winstonallo","@type":"Person","name":"winstonallo"},"datePublished":"2025-07-21T09:37:57.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/137/deepl-python/issues/137"}
