Synchronous and asynchronous queries
Convenient asynchronous callbacks mechanism
Support for kdb+ protocol and types: v3.0, v2.6, v<=2.5
Uncompression of the IPC data stream
Internal representation of data via numpy arrays (lists, complex types) and numpy data types (atoms)
Supported on Python 2.7 and numpy 1.8
For more details please refer to the documentation.

Please do not use old PyPI package name: exxeleron-qpython.
Building package
Documentation
qPython documentation is generated with help of Sphinx document generator. In order to build the documentation, including the API docs, execute: make html from the doc directory.
Documentation is built into the: doc/build/html/ directory.
Compile Cython extensions
qPython utilizes Cython to tune performance critical parts of the code.
Instructions:
Execute: python setup.py build_ext --inplace
Build binary distribution
Instructions:
Execute: python setup.py bdist
Testing
qPython uses py.test as a test runner for unit tests.
Instructions:
Make sure that top directory is included in the PYTHONPATH
Execute: py.test
Requirements
qPython requires numpy 1.8 to run.
Optional requirements have to be met to provide additional features:
