in python, thanks

Write a function named initialLetters that takes one parameter, wordList- a list of words. Create and return a dictionary in which each initial letter of a word in wordListis a key and the corresponding value is a list of the words in wordList that begin with that letter. There should be no duplicate words in any value in the dictionary. For example, the following is correct output: print(initialLetters(horton)) {'T': ['l'], 's': ['say'], 'w': ['what'], 'm': ['mean'], 'a': ['and']}
