I don't think there is a course specifically about the Counter class, but you can find details on the web:

Answer 2

It counts the no of occurrences of each letter and implement them as key value pair in dictionary

You need to import it from collections to use it

Answer 3

from collections import Counter

print(Counter(['a','b','b','b','a','c']))

Answer 4

Ty does anyone know in the python course where does it go over counter. I looked through the sections in control structure and I must have missed it. For instance that whole line "from collections import counter" I never even seen that in the python tutorial.
