Python无法正确比较日期？

Question

我正在尝试比较一些日期：

date1 = request.args['date1']
date2 = request.args['date2']
datesList = readFile('list.csv')
time.strptime(date1, "%d/%m/%Y")
time.strptime(date2, "%d/%m/%Y")
between = 0
for line in datesList:
    time.strptime(line[0], "%d/%m/%Y")
    time.strptime(line[1], "%d/%m/%Y")
    if line[0] <= date1 <= line[1]:
        between = 1
    if line[0] <= date2 <= line[1]:
        between = 2
    if date1 <= line[1] <= date2:
        between = 5
return render_template('index.html', vari = between)

我要求使用GET方法输入两个日期，然后使用strptime将它们转换为日期格式。 dateList.csv如下所示：

17/11/2015,25/11/2015
1/11/2015,23/11/2015
17/12/2015,6/01/2016
28/10/2015,5/11/2015

如果我输入日期，例如04/05/2016和06/05/2016，它仍会between = 5返回。 我的代码有问题吗？或者我使用的是错误的函数？

重新体现您的价值观。

date1 = time.strptime(date1, "%d/%m/%Y")
date2 = time.strptime(date2, "%d/%m/%Y")

between = 0

for line in bookings:
    date1 = time.strptime(line[0], "%d/%m/%Y")
    date2 = time.strptime(line[1], "%d/%m/%Y")
    if line[0] <= date1 <= line[1]:
        between = 1
    if line[0] <= date2 <= line[1]:
        between = 2
    if date1 <= line[1] <= date2:
        between = 5
return render_template('index.html', vari = between)

将它们转换为时间戳，然后如果仍然无法使用，可以将它们作为一个数字进行比较。

time.mktime(datetime.datetime.strptime(date, format).timetuple())

而且您的循环经过“预订”，而我在您的代码中看不到它。 错了吗
