python技巧：日期的遍历

import datetime

def date_range(start_date,end_date):
    for n in range(int((end_date-start_date).days)):
        yield start_date+datetime.timedelta(n)
        
        
        
start=datetime.datetime(2014,11,26,0,0,0)
end=datetime.datetime(2014,12,2,0,0,0)

for i in date_range(start, end):
    print i.strftime(‘%Y%m%d‘)
    #
