Python - Count letters in random strings

Question

I have a bunch of integers which are allocated values using the random module, then converted to letters depending on their position of the alphabet.

I then combine a random sample of these variables into a "master" variable, which is printed to the console.

I want to then count the occurrence of each character, which will later be written to an output file.

Any help on how i would go about doing this?

Answer 1

>>> from collections import Counter
>>> for letter, count in Counter("aaassd").items():
...     print("letter", letter, "count", count)
... 
letter s count 2
letter a count 3
letter d count 1
