LZO

Python bindings for LZO data compression library

Install

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

Examples

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)
