Overview
After you install, the interface to use is a cross between a file
interface and a ste interface. As an example:
>>> fruit = pybloomfilter.BloomFilter(100000, 0.1, '/tmp/words.bloom')
>>> fruit.update(('apple', 'pear', 'orange', 'apple'))
>>> len(fruit)
3
>>> 'mike' in fruit
False
>>> 'apple' in fruit
True
Install
You may or may not want to use Cython. If you have it installed, the
setup file will build the C file from the pyx file. Otherwise, it will
skip that step automatically and build from the packaged C file.
To install:
$ sudo python setup.py install
and you should be set.
