The power of lambda is better shown when you use them as an anonymous function inside another function. Say you have a function definition that takes one argument, and that argument will be multiplied with an unknown number: def myfunc (n): return lambda a : a * n. Use that function definition to make a function that always doubles the number ... ;>>> import heapq >>> l = [5,2,6,8,3,5] >>> heapq.nsmallest(l, 2) [2, 3] So just use: map(lambda x: heapq.nsmallest(x,2)[1], list_of_lists) It's also usually considered clearer to use a list comprehension, which avoids the lambda altogether: [heapq.nsmallest(x,2)[1] for x in list_of_lists]

;With lambda functions, you can do this: numbers = [1, 3, 5, 7, 9] double_result = map(lambda x : x+x, numbers) print(list(double_result)) # [2, 6, 10, 14, 18] As you can see above, we just passed a lambda function — lambda x : x+x — as a parameter to the map function: map(lambda x : x+x, numbers).
