Question

我尝试使用以下代码来解决正常的样本问题，但我的程序并没有进入＆＃39; if＆＃39;条件？

bus_list=[1,2,3,4,5,6,7,8]
seat_list = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20]
bus_num= input("enter the bus number\n")
print(bus_num)
if bus_num in bus_list:
    print("available seats are \n" +seat_list)
    seat_take=input("enter you seat number\n")
    if seat_take in seat_list:
        print("seat available")
    else:
        print("sorry! seat taken")
else:
    print("bus doesn't exists")

Answer 1

input()返回一个字符串，您需要先将其转换为整数：

bus_num= input("enter the bus number\n")

变为：

bus_num = int(input("enter the bus number\n"))

Answer 2

更改此

bus_num = input("enter the bus number\n")

到

bus_num = int(input("enter the bus number\n"))

否则你会遇到这个问题

>>> '5' in [1,2,3,4,5]
False

>>> 5 in [1,2,3,4,5]
True

我不能去'如果'的条件
