Decorators are functions that modify the behavior of other functions without changing their source code.
Decorators are denoted by '@' symbol in Python.
They can be used to add functionality to a function, such as logging or timing.
They can also be used to modify the behavior of a function, such as caching or memoization.
Decorators can be applied to classes, methods, and functions.

Values in a dictionary can be accessed using keys.
Use the key to access the corresponding value in the dictionary.
Values can be accessed using square brackets or the get() method.
If the key is not present, using square brackets will raise a KeyError, while get() will return None or a default value.
Example: my_dict = {'key1': 'value1', 'key2': 'value2'}
my_dict['key1'] will return 'value1'
my_dict.get('key2') will return ...
