Dictionaries in Python are a list of items that are unordered and can be changed by use of built in methods. Dictionaries are used to create a map of unique keys to values.
About Dictionaries in Python
To create a Dictionary, use {} curly brackets to construct the dictionary and [] square brackets to index it.
Separate the key and value with colons : and with commas , between each pair.
Keys must be quoted, for instance: “title” : “How to use Dictionaries in Python”
As with lists we can print out the dictionary by printing the reference to it.
A dictionary maps a set of objects (keys) to another set of objects (values) so you can create an unordered list of objects.
Dictionaries are mutable, which means they can be changed.
The values that the keys point to can be any Python value.
Dictionaries are unordered, so the order that the keys are added doesn’t necessarily reflect what order
