ProgramGuruTo create a dictionary of dictionaries in Python, you can declare a dictionary where the value type is another dictionary. This allows you to create nested dictionaries, with each key in the outer dictionary mapping to another dictionary.
We can create a dictionary of dictionaries in Python by declaring a dictionary where the value type is another dictionary. This example demonstrates how to declare and initialize a dictionary of dictionaries, add key-value pairs to the inner dictionaries, and print the resulting nested dictionary.
For example,
outer_dict where the value type is another dictionary.outer_dict = {
'A': {'X': 1, 'Y': 2},
'B': {'Z': 3}
}
# Print the resulting nested dictionary
print('Dictionary of dictionaries:')
for outer_key, inner_dict in outer_dict.items():
print(f'Key: {outer_key}')
for inner_key, value in inner_dict.items():
print(f' Inner Key: {inner_key}, Value: {value}')Dictionary of dictionaries: Key: A Inner Key: X, Value: 1 Inner Key: Y, Value: 2 Key: B Inner Key: Z, Value: 3
We can create and add to a dictionary of dictionaries dynamically in Python by declaring a dictionary where the value type is another dictionary. This example demonstrates how to declare the outer dictionary, add inner dictionaries dynamically, add key-value pairs to the inner dictionaries, and print the resulting nested dictionary.
For example,
outer_dict where the value type is another dictionary.outer_dict = {}
# Add inner dictionaries dynamically
outer_dict['A'] = {}
outer_dict['B'] = {}
# Add key-value pairs to the inner dictionaries
outer_dict['A']['X'] = 1
outer_dict['A']['Y'] = 2
outer_dict['B']['Z'] = 3
# Print the resulting nested dictionary
print('Dictionary of dictionaries:')
for outer_key, inner_dict in outer_dict.items():
print(f'Key: {outer_key}')
for inner_key, value in inner_dict.items():
print(f' Inner Key: {inner_key}, Value: {value}')Dictionary of dictionaries: Key: A Inner Key: X, Value: 1 Inner Key: Y, Value: 2 Key: B Inner Key: Z, Value: 3
In this tutorial, we learned How to Create a Dictionary of Dictionaries in Python language with well detailed examples.
