 A dictionary is another built-in data type in Python. A dictionary is a collection of data in the form of *key*-*value* pairs. Dictionaries are defined with curly braces `{}` and they contain key-value pairs separated by commas. Each key is followed by a colon `:` and the value:

 ```py
-{"amount": 50.0, "category": "Food"}
+{'amount': 50.0, 'category': 'Food'}
 ```

-In the example above, `amount` and `category` are keys, and `50.0` and `Food` are their the corresponding values.

 You can access values in a dictionary through its keys. You need to use the bracket notation and include the key between the square brackets:

 ```py
-my_dict = {"amount": 50.0, "category": "Food"}

+my_dict = {'amount': 50.0, 'category': 'Food'}
