[![Codecov](https://codecov.io/gh/KxSystems/pyq/branch/master/graph/badge.svg)](https://codecov.io/gh/KxSystems/pyq)[PyQ][2] brings the [Python programming language][4] to the [kdb+ database][5].
Part of the [_Fusion for kdb+_][6] 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][7] in this repository.
## Installation
```bash
pip install pyq
```See detailed [installation instructions][1].
## Usage
For Python programmers:
```bash
$ pyq
```
```python
>>> from pyq import q
>>> 1 + q.til(10)
k('1 2 3 4 5 6 7 8 9 10')
```or run your Python script as
```bash
pyq [python options] python-script
```For q programmers:
```bash
$ q
```
```q
q)p)from math import hypot / prefix python code with p)
q)p)q.h = hypot / import a python function
q)h 3 4 / call the python function from q
5f
```## Documentation
Documentation is available on the [PyQ homepage][2].
