This article is about a pretty useful built-in module in Python, pprint.

The pprint module provides a capability to “pretty-print” arbitrary Python data structures in a well-formatted and more readable way!

In Python, pprint is a module that provides a "pretty printer" for displaying complex data structures such as lists, dictionaries, and tuples. The pprint module can be used to format and display data in a more readable and organized way, making it easier to understand and debug the data structures.

The pprint module can be imported by using the following command: 

import pprint

The pprint module provides a single function, pprint, which takes a data structure as an argument and pretty prints it in a more readable format. For example, the following code: 

import pprint

data = {'key1': {'nested_key1': 'value1', 'nested_key2': 'value2'},
        'key2': [1, 2, 3, 4, 5],
        'key3': (6, 7, 8, 9, 10)}

pprint.pprint(data)

will produce the following output: 

{'key1': {'nested_key1': 'value1', 'nested_key2': 'value2'},
 'key2': [1, 2, 3, 4, 5],
 'key3': (6, 7, 8, 9, 10)}

As you can see, the pprint module formats the data in a more readable way, with nested structures indented and each element of a list or tuple on a new line.

Overall, the pprint module is a useful tool for displaying complex data structures in a more organized and readable format, which can be helpful for debugging and understanding code.
