[PyQ](docs/README.md) brings the [Python programming language](https://www.python.org/about) to the [kdb+ database](https://kx.com).

Part of the [_Fusion for kdb+_](https://code.kx.com/q/interfaces/) 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](https://github.com/KxSystems/pyq/issues) in this repository.

## Installation

```bash

pip install pyq

```

See detailed [installation instructions](docs/install.md).

## 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

```
