Cython bindings for MurmurHash

Examples

hash a string quickly in Python$ python3 -c "from murmurhash.mrmr import hash32; print(hash32('hello'))"

generate consistent hash values for data$ python3 -c "from murmurhash.mrmr import hash64; print(hash64(b'test_data'))"

use murmurhash in a Python script for fast hashing

$ python3 << 'EOF'
from murmurhash.mrmr import hash32
for word in ['apple', 'banana', 'cherry']:
    print(f'{word}: {hash32(word)}')
EOF

compare hash output across multiple strings

$ python3 -c "from murmurhash.mrmr import hash32; items = ['cat', 'dog', 'bird']; [print(f'{i}: {hash32(i)}') for i in items]"

integrate fast hashing into machine learning pipelines

$ python3 << 'EOF'
from murmurhash.mrmr import hash32
features = ['feature_a', 'feature_b', 'feature_c']
hashes = [hash32(f) for f in features]
print(f'Feature hashes: {hashes}')
EOF
