You have a list. Each value from that list can be either a string or an integer. Your task here is to return two values. The first one is a concatenation of all strings from the given list. The second one is a sum of all integers from the given list.
Input: A list of strings and integers.
Output: A list or tuple.
assert list(sum_by_types()) == ["", 0] assert list(sum_by_types([1, 2, 3])) == ["", 6] assert list(sum_by_types(["1", 2, 3])) == ["1", 5] assert list(sum_by_types(["1", "2", 3])) == ["12", 3]
How it’s used: Input the values of different types and different operations with them, depending of type, is the usual thing in development.
