Feb 12, 2025 · In Python, dictionaries are powerful and flexible data structures used to store collections of data in key-value pairs. To get or "access" a value stored in a dictionary, we need to know the corresponding key.

Dictionaries are used to store data values in key:value pairs. A dictionary is a collection which is ordered*, changeable and do not allow duplicates. As of Python version 3.7, dictionaries are ordered. In Python 3.6 and earlier, dictionaries are unordered. Dictionaries are written with curly brackets, and have keys and values:

Mar 12, 2025 · Python Data types are the classification or categorization of data items. It represents the kind of value that tells what operations can be performed on a particular data.
