输入处理好后其实并不难

res = []
while True:
    try:
        res.append(int(input()))
    except:
        k1 = 0
        opt = 0
        k2 = 0
        for i in res:
            if i < 0:
                k1 += 1
            elif i >= 0:
                opt += i
                k2 += 1
        if k2 == 0:
            opt = 0.0
        else:
            opt = round(float(opt/k2)*10)/10
        print(k1)
        print(opt)
        break
