4. Pprint with Custom Indentation

Write a Python program that specifies the indentation while printing a nested dictionary using the pprint module.

"indent" (default 1) specifies the amount of indentation added for each nesting level.

Sample Solution:

Python Code:

import pprint
print("\nNested dictionary with specific indent:")
nested_dict = {
    's1': {
        'a': 2,
        'c': 1,
        'b': 3
    },
    's2': {
        'f': 3,
        'e': 4,
        'd': 6
    },
    's3': {
        'g': 17,
        'h': 18,
        'i': 9
    },
    's4': {
        'a': 7,
        'j': 8,
        'k': 19
    }    
}
pp = pprint.PrettyPrinter(indent=4)
print("\nIndent = 4")
pp.pprint(nested_dict)
print("\nIndent = 15")
pp = pprint.PrettyPrinter(indent=15)
pp.pprint(nested_dict)

Sample Output:

Nested dictionary with specific indent:

Indent = 4
{   's1': {'a': 2, 'b': 3, 'c': 1},
    's2': {'d': 6, 'e': 4, 'f': 3},
    's3': {'g': 17, 'h': 18, 'i': 9},
    's4': {'a': 7, 'j': 8, 'k': 19}}

Indent = 15
{              's1': {'a': 2, 'b': 3, 'c': 1},
               's2': {'d': 6, 'e': 4, 'f': 3},
               's3': {'g': 17, 'h': 18, 'i': 9},
               's4': {'a': 7, 'j': 8, 'k': 19}}
