PyQ - Python for kdb+

PyPI Version Build Windows build status

Total alerts Language grade: Python Language grade: C/C++ Codecov

PyQ brings the Python programming language to the kdb+ database. Part of the Fusion for kdb+ interface collection.

It allows developers to integrate Python and q codes seamlessly in one application. This is achieved by bringing the Python and q interpreters into the same process so that code written in either of the languages operates on the same data. In PyQ, Python and q objects live in the same memory space and share the same data.

Please report issues in this repository.
