常用时间处理方法

• 今天 today = datetime.date.today()
• 昨天 yesterday = today - datetime.timedelta(days=1)
• 上个月 last_month = today.month - 1 if today.month - 1 else 12
• 当前时间戳 time_stamp = time.time()
• 时间戳转datetime datetime.datetime.fromtimestamp(time_stamp)
• datetime转时间戳 int(time.mktime(today.timetuple()))
• datetime转字符串 today_str = today.strftime("%Y-%m-%d")
• 字符串转datetime today = datetime.datetime.strptime(today_str, "%Y-%m-%d")
• 补时差 today + datetime.timedelta(hours=8)
