How would you, an intelligent human being count them?

Describe how you would count them in English, or whatever your native 
language is.

"First I would start a tally for the number of zeroes, tally = 0. Then I 
look at each item in turn, and if it is 0, I add one to the tally. When I 
get to the end, I the number of zeroes is equal to the tally.

Then I do the same for the number of ones, and the number of twos."

Now turn that into Python code. 

tally = 0
for item in list_of_items:
    if item == 0:
        tally = tally + 1

print "The number of zeroes equals", tally
