Here’s my solution to the exercise “This is a common interview question”.

I liked the power of comprehension in Python:

sentence = "This is a common interview question"

# Convert sentence to a set, convert to a list of tupples then sort

sorted_letters = [(letter, sentence.count(letter))

                  for letter in {unique_letters for unique_letters in sentence}]

sorted_letters.sort(key=lambda item: item[1], reverse=True)

print(sorted_letters[0])
