Imdb.py

# Write a function called imdb_dictionary. imdb_dictionary
# should have one parameter, a string representing a
# filename.
#
# On each row of the file will be a performer's name, then
# a semicolon, then a comma-separated list of movies the have
# been in. For example, one file's contents could be:
#
# Robert Downey Jr.; Avengers: Infinity War, Sherlock Holmes 3, Spider-Man: Homecoming
# Scarlett Johansson; Avengers: Infinity War, Isle of Dogs, Ghost in the Shell
# Elizabeth Olsen; Avengers: Infinity War, Kodachrome, Wind River, Ingrid Goes West
#
# You may assume that the only semi-colon will be after the
# performer's name, and that there will be no commas in the
# movie titles.
#
# Return a dictionary where the keys are each actor's name,
# and the values are alphabetically-sorted lists of the movies
# they have been in. For example, if imdb_dictionary was called
# on the file above, the output would be:
# {"Robert Downey Jr.": ["Avengers: Infinity War", "Sherlock Holmes 3", "Spider-Man: Homecoming"],
# "Scarlett Johansson": ["Avengers: Infinity War", "Ghost in the Shell", "Isle of Dogs"],
# Elizabeth Olsen": ["Avengers: Infinity War", "Ingrid Goes West", "Kodachrome", "Wind River"]}
#
# Make sure the list of movies is sorted alphabetically. Don't
# worry about the order the keys (names) appear in the dictionary.


# Add your code here!

# the dropdown in the top left to test other inputs.
#
# If your function works correctly, this will originally
# print (although the order of the keys may vary):
# {"Robert Downey Jr.": ["Avengers: Infinity War", "Sherlock Holmes 3", "Spider-Man: Homecoming"], "Scarlett Johansson": ["Avengers: Infinity War", "Ghost in the Shell", "Isle of Dogs"], Elizabeth Olsen": ["Avengers: Infinity War", "Ingrid Goes West", "Kodachrome", "Wind River"]}
