A really excelent approach to the problem of spam. I'm going through the
classification code and I came across two things I don't understand so far.
I'm trying to understand what these lines of code do in the classifier.py
and chi2.py files:
(yesterday was my first brush with the python language).
clues = self._getclues(wordstream)
for prob, word, record in clues
here we first see prob which is used extensively
throughout the function. It's obviosuly very key to understanding
the function, but I have no idea what value it is, or why
for that matter. word and record don't seem to be used...
and in chi2Q:
assert v & 1 == 0
What's this statment do? (I'm familair with assert statments, but not
what's (v & 1) == 0 mean?
Thanks to anybody who can help me understand this.
