前言

本文主要介紹的是關于利用python 獲取本周，上周，本月，上月，本季的時間，話不多說了，來一起看看實現的方法吧

示例代碼：

import datetimefrom datetime import timedelta now = datetime.datetime.now() # 今天today = nowprint(’--- today = {}’.format(today)) # 昨天yesterday = now - timedelta(days=1)print(’--- yesterday = {}’.format(yesterday)) # 明天tomorrow = now + timedelta(days=1)print(’--- tomorrow = {}’.format(tomorrow)) # 當前季度now_quarter = now.month / 3 if now.month % 3 == 0 else now.month / 3 + 1print(’--- now_quarter = {}’.format(now_quarter)) # 本周第一天和最后一天this_week_start = now - timedelta(days=now.weekday())this_week_end = now + timedelta(days=6 - now.weekday())print(’--- this_week_start = {} this_week_end = {}’.format(this_week_start, this_week_end)) # 上周第一天和最后一天last_week_start = now - timedelta(days=now.weekday() + 7)last_week_end = now - timedelta(days=now.weekday() + 1)print(’--- last_week_start = {} last_week_end = {}’.format(last_week_start, last_week_end)) # 本月第一天和最后一天this_month_start = datetime.datetime(now.year, now.month, 1)this_month_end = datetime.datetime(now.year, now.month + 1, 1) - timedelta(days=1)+ datetime.timedelta(hours=23, minutes=59, seconds=59)print(’--- this_month_start = {} this_month_end = {}’.format(this_month_start, this_month_end)) # 上月第一天和最后一天last_month_end = this_month_start - timedelta(days=1)+ datetime.timedelta(hours=23, minutes=59, seconds=59)last_month_start = datetime.datetime(last_month_end.year, last_month_end.month, 1)print(’--- last_month_end = {} last_month_start = {}’.format(last_month_end, last_month_start)) # 本季第一天和最后一天month = (now.month - 1) - (now.month - 1) % 3 + 1this_quarter_start = datetime.datetime(now.year, month, 1)this_quarter_end = datetime.datetime(now.year, month + 3, 1) - timedelta(days=1)+ datetime.timedelta(hours=23, minutes=59, seconds=59)print(’--- this_quarter_start = {} this_quarter_end = {}’.format(this_quarter_start, this_quarter_end)) # 上季第一天和最后一天last_quarter_end = this_quarter_start - timedelta(days=1)+ datetime.timedelta(hours=23, minutes=59, seconds=59)last_quarter_start = datetime.datetime(last_quarter_end.year, last_quarter_end.month - 2, 1)print(’--- last_quarter_start = {} last_quarter_end = {}’.format(last_quarter_start, last_quarter_end)) # 本年第一天和最后一天this_year_start = datetime.datetime(now.year, 1, 1)this_year_end = datetime.datetime(now.year + 1, 1, 1) - timedelta(days=1)+ datetime.timedelta(hours=23, minutes=59, seconds=59)print(’--- this_year_start = {} this_year_end = {}’.format(this_year_start, this_year_end)) # 去年第一天和最后一天last_year_end = this_year_start - timedelta(days=1)+ datetime.timedelta(hours=23, minutes=59, seconds=59)last_year_start = datetime.datetime(last_year_end.year, 1, 1)print(’--- last_year_start = {} last_year_end = {}’.format(last_year_start, last_year_end))
