I need to code in python a way to count frequencies of words from mulitple strings. I want to keep it in memory and keep apending to it. Once I read a string, count the frquency of words, then add it to the frequencies in memory (but if it is easier you can write to a file and then continue to append to it). So here is an example:

s = "I love you my love"

so frequency is

I 1

love 2

you 1

my 1

now I want a new string s = "I am friend"

it updates the totals to

I 2

love 2

you 1

my 1

am 1

friend 1

I want to keep updating this until I am done and then dump to a file called wordPos using pickle in pythyon.

How do I do this?

I was thinking of using "from collections import Counter" but I am not sure you can. I would need to keep pending to the list.
