非函数 ：python遍历两个日期之间的时间
import datetime
end = '2016-06-01'
start = '2019-07-12'
datestart = datetime.datetime.strptime(start, '%Y-%m-%d')
dateend = datetime.datetime.strptime(end, '%Y-%m-%d')
while datestart > dateend:
datestart -= datetime.timedelta(days=1)
print (datestart.strftime('%Y%m%d'))
url_time = datestart.strftime('%Y%m%d')
print(type(url_time))

时间减去一年、一个月
#pip install python-dateutil

# 时间减去一个月
