while True:
    s = 0
    y = ''
    c = int(input("输入‘1’求和，‘2’求平均值，‘0’退出：\n"))
    if c == 1:
        print('输入2个整数，求和：')
        for i in range(2):
            n = int(input('n%d='%(i+1)))
            s += n
        print(s)
    if c == 2:
        print('输入2个整数，求平均值：')
        for i in range(2):
            n = int(input('n%d='%(i+1)))
            s += n
        print(float(s/2))
    if c == 0:
        print('已退出')
        break
