def algorith(d, s):

And the OP should note that converting between dict d and list of
pairs L is simply a matter of L = d.items() and d = di

Wow, I really should have thought of that! Thanks.

Yes, use the proper tool for the job. Tuples are
Hello,
I'm wondering if there's a quick way of resolving this problem.
In a program, I have a list of tuples of form (str,int), where int is a
count of how often str occurs
e.g. L = [ ("X",1),("Y",2)] would mean "X" occurs once and "Y" occurs
twice
If I am given a string, I want to search L to
