将日期转换为月份和年份

Question

如何使用 python 从以下日期获取月份和年份

日期是

           "2011-07-01 09:26:11"   //This showud display  as "This month"
           "2011-06-07 09:26:11"   //This should display as June            
           "2011-03-12 09:26:11"   //This should display as March            
           "2010-07-25 09:26:11"   // Should display as last year

请让我知道如何使用 python 2.4 获取这些格式

当我在 pandas 数据框中有一个日期变量[具有相同格式]时，如何执行此操作？

Answer 1

import time
import calendar

current = time.localtime()

dates = ["2011-07-01 09:26:11", "2011-06-07 09:26:11", "2011-03-12 09:26:11", "2010-07-25 09:26:11"]

for date in dates:
    print "%s" % date
    date = time.strptime(date, "%Y-%m-%d %H:%M:%S")

    if date.tm_year == current.tm_year - 1:
        print "Last year"    

    elif date.tm_mon == current.tm_mon:
        print "This month"

    else:
        print calendar.month_name[date.tm_mon]

应该大致按照您的要求进行。
