# LZO

Python bindings for [LZO data compression library](http://www.oberhumer.com/opensource/lzo/)

## Install

```sh

pip install git+https://github.com/System233/lzo

```

## Examples

```python

import lzo

data=b'0123456789'

encoded=lzo.lzo1.compress(data)

decoded=lzo.lzo1.decompress(encoded,len(data))

print("Test lzo1:",data==decoded)

encoded=lzo.lzo1x.compress_1(data)

# optional

# encoded=lzo.lzo1x.optimize(encoded,len(data))

decoded=lzo.lzo1x.decompress(encoded,len(data))

print("Test lzo1x:",data==decoded)

# thread safe

lzo1z=lzo.Lzo1z()

encoded=lzo1z.compress_999(data)

decoded=lzo1z.decompress(encoded,len(data))

print("Test lzo1z:",data==decoded)

```
