What are some examples of dictionary comprehensions in Python?

Dictionary comprehensions provide a concise way to create dictionaries. For example, you can create a dictionary of squares like this: {x: x**2 for x in range(5)}.

Can you explain how that works?

Sure! In that example, x takes values from 0 to 4, and for each x, the key is x and the value is x**2, resulting in {0: 0, 1: 1, 2: 4, 3: 9, 4: 16}.

Are there any other examples?

Yes! You can also filter items. For instance, {x: x**2 for x in range(10) if x % 2 == 0} creates a dictionary of squares for even numbers only.

That's really helpful! Thanks!
