@俟宙5480：mysql中python如何插入date -
姓雷18295823983…… 插入date代码如下:import MySQLdb conn = MySQLdb.connect(host='localhost', user='root',passwd='') cursor = conn.cursor() conn.select_db('python') import datetime starttime = datetime.datetime.now() print starttime for j in range(50000): values ...
@俟宙5480：如何使用python中timedelta这个类实现月份的累加 -
姓雷18295823983…… datetime的timedelta没有关于月份的参数.可以使用time.import time now = time.localtime() print now last_month = now[1] - 1 or 12 next_month = (now[1] + 3) % 12 or 12 print last_month print next_month
@俟宙5480：python中怎样通过日历模块显示今天是星期几 -
姓雷18295823983…… import datetime datetime.date.isoweekday(datetime.date.today())
@俟宙5480：python 怎么获取当前日期 -
姓雷18295823983…… 使用time模块的time.localtime()获取当前日期,使用calendar模块calendar.monthrange的来获取指定月份的天数.即可得到月初日期和月末日期,代码如下: import calendarimport timeday_now = time.localtime()day_begin = '%d-%02d-01' %
@俟宙5480：python中datatime模版,来写一个程序获取当前日期并打印出今天是周几 -
姓雷18295823983…… import datetime today = datetime.date.today() weekday = datetime.date.weekday(today)+1 print today print weekday
@俟宙5480：python 时间的格式转化,格式为20130415172500字符串转为datetime类型 -
姓雷18295823983…… python编程用datetime方法进行时间转换,代码如下: $ python Python 2.7.2+ (default, Jul 20 2012, 22:12:53) [gcc 4.6.1] on linux2 Type ＂help＂, ＂copyright＂, ＂credits＂ or ＂license＂ for more information. >>> import datetime >>> dtstr = ＂...
@俟宙5480：python时间模块,如何让时间一次改变一个月? -
姓雷18295823983…… from dateutil.relativedelta import relativedelta date + relativedelta(months=1)
@俟宙5480：Python计算已经过去多少个周末的方法 -
姓雷18295823983…… 代码如下:weekends_between(date(2004,10,1),date(2004,10,10))
