Get the current time:
Python code
import time print time.time() #获取当前时间 print time.strftime("%Y-%m-%d %X ") #获取当前时间(按照指定格式)
Use the time.localtime() method, which formats the timestamp as local time:
Python code
import time print time.localtime(time.time())
Output result: time.struct_time(tm_year=2015, tm_mon =11, tm_mday=513, tm_hour=15, tm_min=48, tm_sec=28, tm_wday=3, tm_yday=309, tm_isdst=0)
Now it looks more promising to format it into the time we want.
time.strftime('%Y-%m-%d',time.localtime(time.time()))
Python code
import time print time.strftime('%Y-%m-%d',time.localtime(time.time()))
Finally, use the time.strftime() method to format the large string of information just now Transformed into what we want, the current result is: 2015-11-05
There are many parameters in time.strftime, which allow you to output what you want more freely:
The following are the parameters of time.strftime:
strftime(format[, tuple]) -> string
Output the specified struct_time (default is the current time) according to the specified format string
1, time and date formatting symbols in python:
%y Two-digit year representation (00-99)
%Y Four-digit year representation (000-9999)
%m Month (01-12)
%d Day in the month (0-31)
%H Hours in 24-hour format (0-23)
%I Hours in 12-hour format (01-12)
%M Minutes (00=59)
%S Seconds (00-59)
%a Local simplified day of the week Name
%A Local complete week name
%b Local simplified month name
%B Local complete month name
%c Local corresponding date representation and time representation
%j Day in the year (001-366)
%p Local Equivalent of A.M. or P.M.
%U The number of weeks in a year (00-53) Sunday is the beginning of the week
%w The day of the week (0-6), Sunday is the beginning of the week
%W The number of weeks in a year (00-53) Monday is the beginning of the week
%x The corresponding local date representation
%X The corresponding local time representation
%Z The name of the current time zone
%% The % number itself
2. Calculate the time difference:
Python code
#coding=utf-8 import time import datetime d1 = datetime.datetime(2013,6,9) d2 = datetime.datetime(2015, 11,5) print (d1 - d2).days
The output result is: 879
3. Calculate the running time difference:
Python code
#coding=utf-8 <pre class="brush:php;toolbar:false"> import time import datetime starttime = datetime.datetime.now() time.sleep(3) endtime = datetime.datetime.now() print (endtime - starttime).seconds <strong> </strong>
The output result is: 3
4. Calculate the date and time ten days later:
Python code
#coding=utf-8 import time import datetime d1 = datetime.datetime.now() d3 = d1 + datetime.timedelta(days =10) print str(d3) print d3.ctime()<strong> </strong>
Output result:
2015-11-15 14:44:04.291000
Sun Nov 15 14:44:04 2015
