1. Pprint Nested Structures

Write a Python program to print a dictionary, nested dictionary, list of dictionaries of dictionaries using the pprint module.

Sample Solution:

Python Code:

import pprint
print("Print dictionary:")
netehan_dict = {'Name': 'Metehan Christel', 'Age': 22, 'City': 'London', 'Country': 'United Kingdom'}
pprint.pprint(netehan_dict)
print("\n")
pprint.pprint(dict([('sape', 4139), ('guido', 4127), ('jack', 4098)]))
print("\nPrint nested dictionary:")
student = {1: {'name': 'Shauna Mathews', 'age': '12'},
           2: {'name': 'Alexandra Powell', 'age': '11'},
           3: {'name': 'Aled Carney', 'age': '11'},
           4: {'name': 'Dennis Walker', 'age': '10'},
           5: {'name': 'Leia Thomas', 'age': '12'}} 
pprint.pprint(student) 
print("\nList of dictionaries of dictionaries:")
list_of_dicts = [
  {
    "dict1": {
      "key1": "val1",
      "key2": "val2"
    }
  },
  {
    "dict2": {
      "key3": "val3",
      "key4": "val4"
    }
  }
]
pprint.pprint(list_of_dicts)

Sample Output:

Print dictionary:
{'Age': 22,
 'City': 'London',
 'Country': 'United Kingdom',
 'Name': 'Metehan Christel'}


{'guido': 4127, 'jack': 4098, 'sape': 4139}

Print nested dictionary:
{1: {'age': '12', 'name': 'Shauna Mathews'},
 2: {'age': '11', 'name': 'Alexandra Powell'},
 3: {'age': '11', 'name': 'Aled Carney'},
 4: {'age': '10', 'name': 'Dennis Walker'},
 5: {'age': '12', 'name': 'Leia Thomas'}}

List of dictionaries of dictionaries:
[{'dict1': {'key1': 'val1', 'key2': 'val2'}},
 {'dict2': {'key3': 'val3', 'key4': 'val4'}}]

For more Practice: Solve these Related Problems:

• Write a Python program to pretty-print a complex nested dictionary containing lists and other dictionaries using pprint, ensuring that the output is readable and well-indented.
• Write a Python function that takes a list of dictionaries (each containing nested dictionaries) and prints the entire structure using pprint with default settings.
• Write a Python script that creates a nested data structure (dictionary within a dictionary with lists as values) and uses pprint to display it, then modify a key’s value and print the updated structure.
• Write a Python program to pretty-print a nested dictionary that contains both Unicode and numeric data, ensuring proper alignment and formatting using pprint.
