Map map(function_to_apply, list_of_inputs) items = [1, 2, 3, 4, 5] squared = list(map(lambda x: x**2, items)) funcs = [multiply, add] for i in range(5): value = list(map(lambda x: x(i), funcs)) Filter number_list = range(-5, 5) less_than_zero = list(filter(lambda x: x < 0, number_list)) print(less_than_zero) #Output : [-5, -4, -3, -2, -1] Reduce from functools import Here, we obtain a reduction for our final product: product = reduce((lambda x, y: x * y), [1, 2, 3, 4]) # Output: 24
