Python不包括两个日期之间的周末

Question

我想计算这两个日期之间的差异，但不包括周末。日期格式如下：

CreateDate  - 2017-08-29 10:47:00
ResolveDate - 2017-09-23 16:56:00

Answer 1

还有一种使用isoweekday（）的python方法：

import datetime, pprint

# isoweekday: Monday is 1 and Sunday is 7
start_date = datetime.date(2017, 10, 1)
end_date = datetime.date(2017, 12, 31)
days = end_date - start_date
valid_date_list = {(start_date + datetime.timedelta(days=x)).strftime('%d-%b-%Y')
                        for x in range(days.days+1)
                        if (start_date + datetime.timedelta(days=x)).isoweekday() <= 5
                       }
print("Business Days = {}".format(len(valid_date_list)))
