You can subtract two date objects. The result is a timedelta object, which has oneattribute: days. This is how many days apart the two dates are. You can read more here: httpss://docs.python.org/3/library/datetime.html2.2 Get Age [3 points]Create, document and test the function, get...
我们可以使用timedelta对象来表示时间差,然后将其应用到日期对象上。 # 引用形式的描述信息:导入timedelta模块fromdatetimeimporttimedelta# 创建一个时间差对象,表示要减去的年份years_to_subtract=timedelta(days=365*years_to_subtract)# 从日期对象中减去指定的年份new_date=date_obj-years_to_subtract 1. 2. 3. ...
You can add (or subtract) a timedelta or multiple thereof to a datetime object to yield a new shifted object: In [18]: from datetime import timedelta In [19]: start = datetime(2011, 1, 7) In [20]: start + timedelta(12) Out[20]: datetime.datetime(2011, 1, 19, 0, 0) In [21...

import datetime:导入datetime模块,用于日期时间的处理。 datetime.datetime.now().date():获取当前日期。 datetime.timedelta(days=days_to_subtract):使用timedelta类来表示时间间隔,这里表示需要减去的天数。 current_date - datetime.timedelta(days=days_to_subtract):通过减法操作得到前几天的日期。
subtract_time_object = time.strptime(subtract_time_string, format_string) 5、计算两个时间之间的差值:我们可以使用time.mktime()函数来计算两个时间之间的差值,这个函数接受一个struct_time对象作为参数,并返回一个浮点数,表示从1970年1月1日以来的秒数,我们可以通过将这个浮点数除以秒数(60秒/分钟,60分钟/小...

dateutil then takes the difference between these two datetime instances and returns the result as a relativedelta instance. In this case, the difference is -1 days, since now happens before tomorrow.dateutil.relativedelta objects have countless other uses. You can use them to find complex ...
Firstly we need to import thedatetime module. importdatetime Then we will set the current_time to a datetime variable. current_date=datetime.datetime.now() The current date is initially in this form: print("String Format of Current Date and Time:",current_date)# String Format of Current Dat...
