Python Tutorial Python Date function instance

The libraries that manipulate dates in Python are: datetime, TIME

In any language, the date function is definitely the most commonly used function. Directly below the instance code

#datetimeimport datetime# Current Date now = Datetime.datetime.now () print (Now.strftime ('%y-%m-%d%h:%m:%s ')) print ( Now.strftime ('%y-%m-%d ')) #string convert to Datetimetime_str = ' 2013-07-29 09:05:00 ' str_convert_2_time = Datetime.datetime.strptime (Time_str, '%y-%m-%d%h:%m:%s ') print (str_convert_2_time) #比较两个日期相差多少天time_strA = ' 2013-07-29 09:05:00 ' time_strb = ' 2013-08-29 09:05:00 ' day = Datetime.datetime.strptime (Time_stra, '%y-%m-%d%h:%m:%s ') Day2 = Datetime.datetime.strptime (TIME_STRB, '%y-%m-%d%h:%m:%s ') Sub_day = Day2-dayprint (' {0} and {1} differ {2} days '. Format (time _stra, TIME_STRB, str (sub_day.days))) #今后的n天的日期n_days = 4now = Datetime.datetime.now () my_date = Datetime.timedelta (days =n_days) N_day = now + my_dateprint (' the date of {0} days from today is: '. Format (n_days)) print (N_day.strftime ('%y-%m-%d%h:%m:%s ')

Operation Result:

>>>

2013-07-29 09:48:16

2013-07-29

2013-07-29 09:05:00

2013-07-29 09:05:00 and 2013-08-29 09:05:00 difference 31 days

The 4-day date from today is:

2013-08-02 09:48:16
