python中两个日期之间的月份列表

Question

我使用此代码查找两个日期之间的月份：

from dateutil.rrule import rrule, MONTHLY
from datetime import datetime
start_date = datetime(2017, 4, 30)
end_date = datetime(2017, 5, 6)
months = [dt.strftime("%m")
          for dt in rrule(MONTHLY, dtstart=start_date,
                          until=end_date)]
In [14]: months
Out[14]: ['04']

我期待['04'，'05']

例如，如果我更改日期

from dateutil.rrule import rrule, MONTHLY
from datetime import datetime
start_date = datetime(2017, 4, 30)
end_date = datetime(2017, 5, 30)
months = [dt.strftime("%m")
          for dt in rrule(MONTHLY, dtstart=start_date,
                          until=end_date)]

In [42]: months
Out[42]: ['04', '05']

Answer 1

试试这个：

from datetime import datetime
from dateutil.relativedelta import relativedelta
from dateutil.rrule import rrule, MONTHLY


start_date = datetime(2017,4,30)
end_date = datetime(2017,5,6)

oneMonth = relativedelta(months=1)

months = [dt.strftime("%m")
          for dt in rrule(MONTHLY, dtstart=start_date,
                          until=end_date+oneMonth)]

print months

输出：

['04', '05']
