python code. define the run function. The other three functions are already done I just need the code for run function only. Instructions are given within the quotations.
1)def invert_dict(d):"""
Given a dictionary d, create the invert of the dictionary where
the key is a value v in d, and v is mapped to a set of keys in original
d whose values are equal to v.
Return the inverted dictionary mapping value to set of keys """
2)def histogram(words): """
Given a list of words, create a histogram dictionary where the key is the length of a word and the value is the count of how many words in the list are of that length. Return the histogram dictionary mapping length to word counts """
3)def max_kv(d): """
Given a dictionary, return a tuple of key value pair where the key is the largest in d. """
4)def run(): """
Get words list from the file listed in argv[1]; create histogram of count of each word length; create invert dictionary that maps count to list of word length; use invert dictionary to find the list of word length with the most popular word count (use max_kv) """
words = get_words(argv[1])
# fill in code here
# modify the line below so that count, length_set has the right values
count, length_set = 1, {1}
print(f"These word length {length_set} each has {count} words.")
