python中 遍历时间

import datetime
def main():
	begin = datetime.date(2018, 1, 1)
	end = datetime.date(2018, 12, 1)

	for i in range((end - begin).days + 1):
		day = begin + datetime.timedelta(days=i)
		print(str(day))
if __name__ == '__main__':
	main()

部分输出如下：

2018-11-21
2018-11-22
2018-11-23
2018-11-24
2018-11-25
2018-11-26
2018-11-27
2018-11-28
2018-11-29
