Question 1:

Write a function called longest_word_length, which takes a string as input and returns a number giving the length (number of characters) in the longest single word in the string. For example , calling the function with the code below:

longest_word_length("This is a sentence")

returns the value 8 because "sentence" is the longest word.

Question 2

Write a function called word_freq that accepts a string parameter str and uses a dictionary accumulation pattern to return a dictionary with the frequency of words in the str. For example, running the code below:

s = 'it is what it is and only what it is' print(word_freq(s))

Displays the output below:

{'it': 3, 'is': 3, 'what': 2, 'and': 1, 'only': 1}
