Getting Started

To use this package in your program, simply type

pip install cityhash

After that, you should be able to import the module and do things with it (see Example Usage below).

Example Usage

The package contains 64- and 128-bit implementations of the CityHash algorithm, named as follows:

>>> from cityhash import CityHash32, CityHash64, CityHash128
>>> print(CityHash32("abc"))
795041479
>>> print(CityHash64("abc"))
2640714258260161385
>>> print(CityHash128("abc"))

Development

For those who want to contribute, here is a quick start using some makefile commands:

git clone https://github.com/escherba/python-cityhash.git
cd python-cityhash
make env           # creates a Python virtualenv
make test          # runs both Python and C++ tests

Authors

The Python bindings were originally written by Alexander [Amper] Marshalov, then repackaged for PyPI (with minor improvements) by Eugene Scherba. The original CityHash algorithm is by Google.
