Great! How about a function returning a dictionary?
Exercise
Write a function named get_character_frequencies() that takes a string as input and returns a dictionary of lowercase characters as keys and the number of their occurrences as values. Ignore the case of a character.
Stuck? Here's a hint!
First, create a dictionary:
freq_dict = {}
Then iterate over characters in the text and update the values in the dictionary accordingly. To get the values in the dictionary under a given character, you can use:
freq_dict[character]
Remember to convert letters to lowercase with the lower method:
letter.lower()
