# Langfuse Python SDK
[](https://opensource.org/licenses/MIT)
[](https://github.com/langfuse/langfuse-python/actions/workflows/ci.yml?query=branch%3Amain)

## Installation
> [!IMPORTANT]
> The SDK was rewritten in v2 and released on December 17, 2023. Refer to the [v2 migration guide](https://langfuse.com/docs/sdk/python#upgrading-from-v1xx-to-v2xx) for instructions on updating your code.
```
pip install langfuse
```
Full documentation: https://docs.langfuse.com/sdk/python
Langchain documentation: https://docs.langfuse.com/langchain
## Development
### Add Poetry plugins
```
poetry self add poetry-dotenv-plugin
poetry self add poetry-bumpversion
```
### Install dependencies
```
poetry install --all-extras
```
### Add Pre-commit
```
poetry run pre-commit install
```
### Tests
#### Setup
- Add .env based on .env.example
#### Run
- Run all
```
poetry run pytest -s -v --log-cli-level=INFO
```
- Run a specific test
```
poetry run pytest -s -v --log-cli-level=INFO tests/test_sdk.py::test_flush
```
- E2E tests involving OpenAI and Serp API are usually skipped, remove skip decorators in [tests/test_langchain.py](tests/test_langchain.py) to run them.
### Update openapi spec
1. Generate Fern Python SDK in [langfuse](https://github.com/langfuse/langfuse) and copy the files generated in `generated/python` into the `langfuse/api` folder in this repo.
2. Execute the linter by running `poetry run ruff format .`
3. Rebuild and deploy the package to PyPi.
### Publish release
1. `poetry version patch`
- `poetry version prepatch` for pre-release versions
2. `poetry install`
3. `poetry build`
4. `git commit -am "chore: release v{version}"`
5. `git push`
6. `git tag v{version}`
7. `git push --tags`
8. `poetry publish`
- Create PyPi API token: https://pypi.org/manage/account/token/
- Setup: `poetry config pypi-token.pypi your-api-token`
9. Create a release on GitHub with the changelog
