Question
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.")
