Get the number of occurrences of each character

Question

Given the string:

a=\'dqdwqfwqfggqwq\'

How do I get the number of occurrences of each character?

Answer 1

You can do this:

listOfCharac={}
for s in a:
    if s in listOfCharac.keys():
        listOfCharac[s]+=1
    else:
        listOfCharac[s]=1
print (listOfCharac)

Output {'d': 2, 'f': 2, 'g': 2, 'q': 5, 'w': 3}

This method is efficient as well and is tested for python3.
