檢查列表理解中的總和

Question

是否可以以相同的方式檢查列表中數字的總和並進行另一個運算，除非總和超過50？

        k = input("input digits separated by spaces:")
        try:
            [int(i) for i in k.split()]
        except ValueError:
            print("input only digits")

最主要的不是用兩個除了塊的結構，而是要使其盡可能簡單，請確保列表的總和不超過50。

Answer 1

    k = input("Input integers separated by spaces:")
    try:
        the_list = [int(i) for i in k.split()]
        if sum(the_list) > 50:
            raise ValueError("The user's numbers' summation is too large.")
    except ValueError:
        print("Input only integers separated by spaces with sum not greater than 50.")

Answer 2

assert sum([int(i) for i in k.split()]) <= 50並添加一個except AssertionError可以解決問題：

k = input("input digits separated by spaces: ")
try:
    assert sum([int(i) for i in k.split()]) <= 50
except ValueError:
    print "input only digits"
except AssertionError:
    print "Sum of digits is grater than 50"

雖然我必須說我覺得這是一個很差的設計...
