TypeError：不支持的操作数类型 - ：'int'和'list' [英] TypeError: unsupported operand type(s) for -: 'int' and 'list'

问题描述

我正在尝试在python中创建一个程序，它会告诉你使用Zeller算法出生的那一周 http://en.wikipedia.org/wiki/Zeller%27s_congruence 但它给了我这个错误

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

TypeError：不支持的操作数类型 - ：'int'和'list'

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

为什么会这样？

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

（这是我自己创建的第一个程序，所以请好一点;）

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

推荐答案

@mellamokb回答了你的直接问题所发生的事情并发表评论...

然而，我会指出Python已经内置并且会更容易：

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

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

然后你可以更容易地对一个实际上是 datetime 的对象执行计算，而不是合成的字符串......

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