What are some examples of Python lambda functions?

Can you give me some examples of Python lambda functions?

Sure! A lambda function in Python is a small anonymous function. For example, you can use it to add two numbers: add = lambda x, y: x + y.

What about using lambda with the map function?

Great question! You can use lambda with map to apply a function to all items in a list. For example: list(map(lambda x: x * 2, [1, 2, 3])) will return [2, 4, 6].

Can you show me an example with filter?

Absolutely! You can use lambda with filter to filter out items from a list. For instance: list(filter(lambda x: x > 2, [1, 2, 3, 4])) will return [3, 4].

What about sorting a list with a lambda function?

You can sort a list using a lambda function as the key. For example: sorted(['apple', 'banana', 'cherry'], key=lambda x: len(x)) will sort the fruits by their name length.
