Problem 1
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}
Problem 2
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 wordList is 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:…
