This dictionary creation could be rewritten as a dictionary literal

Yes, that is correct. In Python, you can create a dictionary by using curly braces {} and separating the key-value pairs with colons. For example, instead of writing:

my_dict = dict()
my_dict['key1'] = 'value1'
my_dict['key2'] = 'value2'

You can write:

my_dict = {'key1': 'value1', 'key2': 'value2'}

This is called a dictionary literal, which is a more concise way of creating a dictionary. Note that the keys must be hashable and unique, and the values can be any data type.
