问题描述
我正在尝试使用datetime从python中的当前日期获取最近90天的星期日(3个月的星期日)的日期.我能够在周日获得最近3个月的服务,但不能从当前日期开始.通过此代码,我可以获取当前月份和最近2个月(共3个月)的星期日列表.
I am trying to get a date of last 90 days Sundays (3 months Sunday) from the current date in python using datetime. I am able to get last 3 months Sunday but not from current date. With this code i am getting list of Sunday from the current month and last 2 month (total 3 months).
from datetime import date, timedelta, datetime
def list_sunday(year, month, day):
try:
for i in range(1,4):
d = date(year, month, day)
d += timedelta(days = 6 -d.weekday())
while d.month==month:
yield d
d += timedelta(days =+ 7)
if month > 1:
month = month - 1
else:
month = 12
year = year - 1
i+=1
except Exception as e:
log.error("XXX %s" % str(e))
for d in list_sunday(2019, 4, 05):
print d

推荐答案
from datetime import date, timedelta
from pprint import pprint
def is_sunday(day):
return day.weekday() == 6
def sundays_within_last_x_days(num_days = 90):
result = []
end_date = date.today()
start_date = end_date - timedelta(days = num_days)
while start_date <= end_date:
if is_sunday(start_date):
result.append(start_date)
start_date += timedelta(days = 1)
return result
if __name__ == "__main__":
dates = sundays_within_last_x_days(30)
pprint(dates)
