Implement the build_dictionary() function to build a word frequency dictionary from a list of words. Ex: If the words list is: ["hey", "hi", "Mark", "hi", "mark"] the dictionary returned from calling build_dictionary(words) is: {'hey': 1, 'hi': 2, 'Mark': 1, 'mark': 1} Ex: If the words list is: ["zyBooks", "now", "zyBooks", "later", "zyBooks", "forever"] the dictionary returned from calling build_dictionary(words) is: {'zyBooks': 3, 'now': 1, 'later': 1, 'forever': 1} The main code builds the word list from an input string, calls build_dictionary() to build the dictionary, and displays the dictionary sorted by key value. Ex: If the input is: hey hi Mark hi mark the output is: Mark: 1 hey: 1 hi: 2 mark: 1 python # The words parameter is a list of strings. def build_dictionary(words): # The frequencies dictionary will be built with your code below. # Each key is a word string and the corresponding value is an integer # indicating that word's frequency. ''' Type your code here (remove the "pass" statement below) ''' pass # The following code asks for input, splits the input into a word list, # calls build_dictionary(), and displays the contents sorted by key. if __name__ == '__main__': words = input().split() your_dictionary = build_dictionary(words) sorted_keys = sorted(your_dictionary.keys()) for key in sorted_keys: print(key + ': ' + str(your_dictionary[key]))
Implement the build_dictionary() function to build a word frequency dictionary from a list of words.
Ex: If the words list is:
["hey", "hi", "Mark", "hi", "mark"]
the dictionary returned from calling build_dictionary(words) is:
{'hey': 1, 'hi': 2, 'Mark': 1, 'mark': 1}
Ex: If the words list is:
["zyBooks", "now", "zyBooks", "later", "zyBooks", "forever"]
the dictionary returned from calling build_dictionary(words) is:
{'zyBooks': 3, 'now': 1, 'later': 1, 'forever': 1}
The main code builds the word list from an input string, calls build_dictionary() to build the dictionary, and displays the dictionary sorted by key value.
Ex: If the input is:
hey hi Mark hi mark
the output is:
Mark: 1
hey: 1
hi: 2
mark: 1
