Question

到目前为止，这是我得到的，如果没有这样的值，如何使它返回False？

def pairSum(l, s):
    a = 0
    b = 1
    for i in l:
        if l[a]+l[b] == s:
            return True
        a=a+1
        b=b+1

编辑：我刚刚意识到，此函数只能找到两个相加的连续数字。我打算创建一个函数，该函数确定列表中的任何两个数字是否等于s，而不是两个连续的数字。很抱歉提供误导性信息。

如果列表的两个连续数字相加导致f = lambda x,y: x+y def func(l, s): for i in range(len(l)-1): if f(l[i],l[i+1]) == s: return True return False和True，则返回s。

如果要检查False中任意两个数字的加法是否加到l上，则

python：汇总两个数字
