Best way to turn word list into frequency dict

Question

What\'s the best way to convert a list/tuple into a dict where the keys are the distinct values of the list and the values are the the frequencies of those distinct values?<

Answer 1

I think using collection library is the easiest way to get it. But If you want to get the frequency dictionary without using it then it's another way,

l = [1,4,2,1,2,6,8,2,2]
d ={}
for i in l:
    if i in d.keys():
        d[i] = 1 + d[i]
    else:
        d[i] = 1
print (d)

op:

{1: 2, 4: 1, 2: 4, 6: 1, 8: 1}

Answer 2

Actually, the answer of Counter was already mentioned, but we can even do better (easier)!

from collections import Counter
my_list = ['a', 'b', 'b', 'a', 'b', 'c']
Counter(my_list)  # returns a Counter, dict-like object
>> Counter({'b': 3, 'a': 2, 'c': 1})
