Lab Dictionaries

Write a dictionary that gives context to 'internet memes'. Write a program, dictionary_lab.py, that prompts a user for what word they want to look up. If it's in the dictionary, then you will print out the definition. If the word is not in the dictionary the program will print out that the word is not defined.

Example

Example:

>>> python3 dictionary_lab.py
What word would you like to look up? nbd
nbd: a phrase meaning no big deal
What word would you like to look up? kittens
Sorry, kittens is not defined
What would would you like to look up?

Bonus

Create a way to update values and add key/value pairs to the dictionary. Search for dictionaries in the Python documentation.
