How much do you know about Python?map() applies a function to each element of an iterable (list, tuple, etc.) and returns a map object that can be converted to a list or another iterable. For example: list(map(lambda x: x*2, [1, 2, 3])) returns [2, 4, 6]. In modern Python, list comprehensions are often preferred for their readability: [x*2 for x in [1, 2, 3]], but map() is still useful, especially with existing functions or multiple iterables.
