Python取日期范围循环操作的两种方法

 方法一：

import  datetime

begin = datetime.date(2019, 1, 21)
end = datetime.date(2019, 4, 7)
for i in range((end - begin).days + 1):
    day = begin + datetime.timedelta(days=i)
    print(str(day))

 方法二：

import datetime

begin = datetime.date(2014,6,1)
end = datetime.date(2014,6,7)
d = begin
delta = datetime.timedelta(days=1)
while d <= end:
    print (d.strftime("%Y-%m-%d"))
    d += delta

 

import datetime

def init_date_list(begin_date, end_date):
    date_list = []
    begin_date = datetime.datetime.strptime(begin_date, '%Y%m%d')
    end_date = datetime.datetime.strptime(end_date, '%Y%m%d')
    while begin_date<=end_date:
        date_str = begin_date.strftime('%Y%m%d')
        date_list.append(date_str)
        begin_date += datetime.timedelta(days=1)
    return date_list
