调用函数分割查询

data = [1, 3, 6, 7, 9, 12, 14, 16, 17, 18, 20, 21, 22, 23, 30, 32, 33, 35]
num=int(input('输入您想找的数字：'))
def sch(num , data):
    if len(data)>1:
        start_data=int(len(data)/2)
        data_value = data[start_data]
        if  num > data_value:
            data = data[start_data:]
            sch(num , data)
        elif num < data_value:
            data = data[:start_data]
            sch(num , data)
        else:
            print("找到了!")
            return
    else:
        print("找到了!") if data[0] == num else print("没找到!")
sch(num,data)
