c = Counter("thiiss wiill caalcullateeee theee numbeeer of characters")
# now when we print c, it will have the following data:
Counter({'e': 11, ' ': 6, 'l': 5, 'a': 5, 't': 4, 'i': 4, 'c': 4, 'h': 3, 's': 3, 'r': 3, 'u': 2, 'w': 1, 'n': 1, 'm': 1, 'b': 1, 'o': 1, 'f': 1})
# And now we can check the occurrence of each of the characters as follows:
count_e = c.get('e') # returns 11
