Python bindings for Kuiper
Python bindings for Kuiper so you can compile and run transformations from a Python runtime.
The language itself is documented here.
from kuiper import compile_expression
expression = compile_expression('{"theAnswer": input.numericValue + 27}', ["input"])
value = expression.run('{"numericValue": 15}')
print(value)
The compile_expression function might raise a KuiperCompileError, and
otherwise returns a KuiperExpression object. The KuiperExpression.run(...)
method might raise a KuiperRuntimeError. Both of these exceptions are
subclasses of the KuiperError base class.
The packakge is available on PyPI. To use
it in your project, add it to your project file with your project manager of
choice. For example, using uv:
uv add cognite-kuiper
Development
We use PyO3 to create the bindings.
This project uses uv to manage dependencies and such. To set up your local development environment, first make sure uv is installed:
pip install -U uv
uv will automatically recompile the Rust code whenever it changes and install
it in the virual environment.
To run the test suite, run
uv run pytest
