接下来,我们需要定义一个函数,该函数将接受一个Timestamp作为参数,并返回提取出的年份。 defextract_year_from_timestamp(timestamp):# 将Timestamp转换为日期格式date=datetime.datetime.fromtimestamp(timestamp)# 从日期格式中提取年份year=date.yearreturnyear 1. 2. 3. 4. 5. 6. 7. 8. 以上代码中,我们...
datetime.fromtimestamp(timestamp[, tz]):根据时间戮创建一个datetime对象,参数tz指定时区信息; datetime.utcfromtimestamp(timestamp):根据时间戮创建一个datetime对象; datetime.combine(date, time):根据date和time,创建一个datetime对象; datetime.strptime(date_string, format):将格式字符串转换为datetime对象,data...

从Python 2.4 版开始,cx_Oracle 自身可以处理 DATE 和 TIMESTAMP 数据类型,将这些列的值映射到 Python 的 datetime 模块的 datetime 对象中。因为 datetime 对象支持原位的运算操作,这可以带来某些优势。内置的时区支持和若干专用模块使

If we don’t want to use variables, we can hard code the date and/or the mask into the function call: datetime_object = datetime.strptime('07/11/2019', '%m/%d/%Y') If we happen to have a timestamp associated with our date, we can add that in as well. This will eliminate that...
