Dictionary Fill in the Blank

Practice building dictionaries by filling in missing keys and values.

Part 1 — Fill in the blanks

The dictionary below is missing some keys and values. Fill in each ____ with the correct answer. You can Google anything you don’t know.


movie = {
    "title": "The Dark Knight",
    "____": 2008,
    "genre": "____",
    "____": "Christopher Nolan",
    "cast": ["Christian Bale", "____", "Aaron Eckhart"]
}

1. Fill in the missing key for 2008 (hint: what does that number represent?).

2. Fill in the genre.

3. Fill in the missing key for "Christopher Nolan".

4. Fill in the missing cast member (hint: he won an Academy Award for this role).

Part 2 — Build your own

Now create a dictionary for a movie of your choice. Use the same fields.


movie = {
    "title": "",
    "year": ____,
    "genre": "",
    "director": "",
    "cast": ["", "", ""]
}

1. Pick a movie and fill in all five fields.

2. Print a sentence using at least two values from your dictionary. For example: "The Dark Knight was directed by Christopher Nolan."

Part 3 — Loop through your dictionary

Dictionaries have a .items() method that lets you loop through every key-value pair — the same way you loop through a list.

1. Use .items() to loop through your movie dictionary and print each key and value on its own line.

2. Try the same loop on the Dark Knight dictionary from Part 1. Notice anything different about the cast field?
