To filter a dictionary based on keys in Python, you can use a dictionary comprehension. This allows you to create a new dictionary with the key-value pairs that satisfy a specific condition based on keys.
We can filter a dictionary based on keys in Python using a dictionary comprehension. This example demonstrates how to declare and initialize a dictionary, use a dictionary comprehension to filter the dictionary based on keys, and print the filtered dictionary.
For example,
my_dict
with integer keys and string values.my_dict = {
1: 'One',
2: 'Two',
3: 'Three'
}
# Filter the dictionary to include only keys greater than 1
filtered_dict = {k: v for k, v in my_dict.items() if k > 1}
# Print the filtered dictionary
print('Filtered dictionary:')
for key, value in filtered_dict.items():
print(f'Key: {key}, Value: {value}')
Filtered dictionary: Key: 2, Value: Two Key: 3, Value: Three
We can filter a dictionary to include only specific keys in Python using a dictionary comprehension. This example demonstrates how to declare and initialize a dictionary, use a dictionary comprehension to filter the dictionary to include only the keys 1 and 3, and print the filtered dictionary.
For example,
my_dict
with integer keys and string values.my_dict = {
1: 'One',
2: 'Two',
3: 'Three'
}
# Filter the dictionary to include only the keys 1 and 3
filtered_dict = {k: v for k, v in my_dict.items() if k in [1, 3]}
# Print the filtered dictionary
print('Filtered dictionary:')
for key, value in filtered_dict.items():
print(f'Key: {key}, Value: {value}')
Filtered dictionary: Key: 1, Value: One Key: 3, Value: Three
