我有一个日期“10/10/11(m-d-y)”，我想用Python脚本添加5天。请考虑一个在月底也适用的通用解决方案。
我使用以下代码:
import re
from datetime import datetime
StartDate = "10/10/11"
Date = datetime.strptime(StartDate, "%m/%d/%y")
打印日期->正在打印'2011-10-10 00:00:00'
现在我想在这个日期上加5天。我使用了以下代码:
EndDate = Date.today()+timedelta(days=10)
返回以下错误:
name 'timedelta' is not defined
当前回答
这可能会有帮助:
from datetime import date, timedelta
date1 = date(2011, 10, 10)
date2 = date1 + timedelta(days=5)
print (date2)
其他回答
试试这个:
在当前日期上增加5天。
from datetime import datetime, timedelta
current_date = datetime.now()
end_date = current_date + timedelta(days=5) # Adding 5 days.
end_date_formatted = end_date.strftime('%Y-%m-%d')
print(end_date_formatted)
从当前日期减去5天。
from datetime import datetime, timedelta
current_date = datetime.now()
end_date = current_date + timedelta(days=-5) # Subtracting 5 days.
end_date_formatted = end_date.strftime('%Y-%m-%d')
print(end_date_formatted)
我已经看到了一个熊猫的例子，但这里有一个转折，你可以直接导入Day类
from pandas.tseries.offsets import Day
date1 = datetime(2011, 10, 10)
date2 = date1 + 5 * Day()
一般来说，你现在已经有了一个答案，但也许我创建的类也会有帮助。对我来说，它解决了我在Pyhon项目中遇到的所有需求。
class GetDate:
def __init__(self, date, format="%Y-%m-%d"):
self.tz = pytz.timezone("Europe/Warsaw")
if isinstance(date, str):
date = datetime.strptime(date, format)
self.date = date.astimezone(self.tz)
def time_delta_days(self, days):
return self.date + timedelta(days=days)
def time_delta_hours(self, hours):
return self.date + timedelta(hours=hours)
def time_delta_seconds(self, seconds):
return self.date + timedelta(seconds=seconds)
def get_minimum_time(self):
return datetime.combine(self.date, time.min).astimezone(self.tz)
def get_maximum_time(self):
return datetime.combine(self.date, time.max).astimezone(self.tz)
def get_month_first_day(self):
return datetime(self.date.year, self.date.month, 1).astimezone(self.tz)
def current(self):
return self.date
def get_month_last_day(self):
lastDay = calendar.monthrange(self.date.year, self.date.month)[1]
date = datetime(self.date.year, self.date.month, lastDay)
return datetime.combine(date, time.max).astimezone(self.tz)
如何使用
self.tz = pytz.timezone("Europe/Warsaw") - here you define Time Zone you want to use in project GetDate("2019-08-08").current() - this will convert your string date to time aware object with timezone you defined in pt 1. Default string format is format="%Y-%m-%d" but feel free to change it. (eg. GetDate("2019-08-08 08:45", format="%Y-%m-%d %H:%M").current()) GetDate("2019-08-08").get_month_first_day() returns given date (string or object) month first day GetDate("2019-08-08").get_month_last_day() returns given date month last day GetDate("2019-08-08").minimum_time() returns given date day start GetDate("2019-08-08").maximum_time() returns given date day end GetDate("2019-08-08").time_delta_days({number_of_days}) returns given date + add {number of days} (you can also call: GetDate(timezone.now()).time_delta_days(-1) for yesterday) GetDate("2019-08-08").time_delta_haours({number_of_hours}) similar to pt 7 but working on hours GetDate("2019-08-08").time_delta_seconds({number_of_seconds}) similar to pt 7 but working on seconds
如果现在想要添加日期，可以使用这段代码
from datetime import datetime
from datetime import timedelta
date_now_more_5_days = (datetime.now() + timedelta(days=5) ).strftime('%Y-%m-%d')
首先导入timedelta和date。
from datetime import timedelta, date
date.today()将返回今天的日期时间，然后你可以给它添加一个timedelta:
end_date = date.today() + timedelta(days=10)
