Dictionaries are Python's implementation of an associative array, which is more often known as a data structure. A dictionary is made up of a set of key-value pairs. Each key-value pair corresponds to a certain value.
Data values are stored in key:value pairs using dictionaries. A dictionary is an ordered*, changing collection that does not allow duplication. Dictionaries are now sorted as of Python 3.7. Dictionaries in Python 3.6 and before are not sorted.
A Dictionary is built in Python by enclosing a succession of entries in curly braces and separating them with a comma. The Dictionary stores pairs of values, one of which is the Key and the other is the Key:value pair element.
The word “dictionary” comes from Latin dictionarium, which means “a book of words”. There are many types of dictionaries including a general one, an encyclopedic one, and a specialized dictionary.
The Python dictionary data type is a collection of key/value pairs that can be stored in memory or on disk, and it has many useful features including fast iteration, sorting, set operations, and more.
