This is a minimalistic Count-min Sketch for Python, featuring some cool things like: - Being able to count anything that is hash-able by python (numbers, strings, tuples, inmutables, duck-typeds, etc.). - Tests - No dependencies - No foreign languages, just 100% python.
This software was written by Rafael Carrascosa, you can contact me at rafacarrascosa on gmail.
from countminsketch import CountMinSketch
sketch = CountMinSketch(1000, 10) # table size=1000, hash functions=10
sketch.add("oh yeah")
sketch.add(tuple())
sketch.add(1, value=123)
print sketch["oh yeah"] # prints 1
print sketch[tuple()] # prints 1
print sketch[1] # prints 123
print sketch["non-existent"] # prints 0CountMinSketch is on PyPI, so you can install it with
