类型错误:不支持的操作和类型:'int'和'list'

I'm trying to create a program in python that will tell you the day of the week you were born using the Zeller algorithm http://en.wikipedia.org/wiki/Zeller%27s_congruence but it's giving me this error

我正在尝试用python创建一个程序，它会告诉你你出生的那一天是哪天，使用Zeller算法http://en.wikipedia.org/wiki/zeller%27s_但是它给了我这个错误

TypeError: unsupported operand type(s) for -: 'int' and 'list'

类型错误:不支持的操作和类型:'int'和'list'

Why is that?

这是为什么呢?

date = raw_input ("Introduce here the day, month and year you were born like this: DDMMYYYY")

if date.isdigit() and len(date) == 8:
    day = date[0:2]
    month = date[2:4]
    year = date[4:8]
    day = int(day)
    month = int(month)
    year = int(year)
    result = (day + (month + 1) * 2.6, + year % 100 + (year % 100) / 4 - 2 * [year / 100]) % 7

(It's the first program I create by myself, so be nice please ;) )

(这是我自己设计的第一个程序，所以请好好表现;)

What's happening in answer to your direct question has been answered by @mellamokb and comments...

关于你直接问题的回答，@mellamokb给出了答案。

However, I would point out that Python already this builtin and would make it easier:

然而，我要指出的是，Python已经构建了这个构建，并且会使它更容易:

from datetime import datetime
d = datetime.strptime('1312981', '%d%m%Y')
# datetime(1981, 12, 13, 0, 0)

Then you can perform calculations more easily on an object that is actually a datetime rather than co-erced strings...

然后，您就可以更容易地对一个实际上是datetime(日期时间)而不是共写字符串的对象执行计算……

I think 2 * [year / 100] should be parentheses instead of brackets, otherwise it indicates you want to make a single-element list:

我认为2 * [year / 100]应该是圆括号，而不是括号，否则表示你想做一个单元素列表:

(year % 100) / 4 - 2 * (year / 100))
                       ^          ^ change [] to ()
