How can I filter a dictionary in Python?

How can I filter a dictionary in Python?

You can use dictionary comprehensions to filter a dictionary. For example, {k: v for k, v in my_dict.items() if v > 10} filters out items with values greater than 10.

Can you show me a complete example?

Sure! Here's a complete example:

my_dict = {'a': 5, 'b': 15, 'c': 10}
filtered_dict = {k: v for k, v in my_dict.items() if v > 10}
print(filtered_dict)  # Output: {'b': 15}

What if I want to filter by keys instead?

You can do that too! Just modify the condition in the comprehension. For example:

filtered_dict = {k: v for k, v in my_dict.items() if k in ['a', 'b']}

Is there a way to filter using a function?

Yes! You can use the filter() function along with a lambda. For example:

filtered_dict = dict(filter(lambda item: item[1] > 10, my_dict.items()))
