(ANSWER USING PYTHON 3.6)

Write a function named initialLetterCount that takes one parameter, wordList -- a list of words. Create and return a dictionary in which each initial letter of a word in wordList is a key and the corresponding value is the number of words in wordList that begin with that letter. The keys in the dictionary should be case-sensitive, which means 'a' and 'A' are two different keys.

For example, the following is correct output:

horton = ['I', 'say', 'what', 'I', 'mean', 'and', 'I', 'mean', 'what', 'I', 'say']

print(initialLetterCount(horton))

{'I': 4, 's': 2, 'w': 2, 'm': 2, 'a': 1}
