datetime.datetime(2000, 2, 3, 0, 0) 我们可以看到,现在对象中有两个零(分别代表)小时和分钟。同时秒数也被省略了。 在许多情况下,我们想知道当前的确切时间。可以使用 datetime 类的 now 方法: # Time at the moment now = datetime.now now Output: datetime.datetime(2022, 8, 1, 0, 9, 39, 611...

Dates & Times in Python – datetime Module Introduction to timedelta Objects in Python Convert timedelta to Seconds in Python Calculate Number of Hours, Minutes & Seconds Between Two datetimes Subtract Seconds, Minutes & Hours from datetime in Python Add Seconds, Minutes & Hours to datetime Object...
Earlier, you used the subtraction operator to find the difference between two Python datetime instances, PYCON_DATE and now. With relativedelta, instead of using the subtraction operator, you need to pass the two datetime instances as arguments : Python >>> now datetime.datetime(2020, 1, 26...
Let’s understand the main classes under this module, as we’ll be converting them into the datetime objects: 1. datetime.date This class represents a date (year, month, and day) and provides methods for working with dates, such as calculating the difference between two dates and formatting...
datetime模块定义了5个类,分别是:datetime.date、datetime.time、datetime.datetime、datetime.timedelta、tzinfo。 一、datetime.date:表示日期的类。 date类有三个参数,datetime.date(year,month,day),返回year-month-day 方法: 1.datetime.date.today()
转换时间戳为datetime格式,验证数据完整性(无缺失值)。 故障事件整合 根据外部报告定义故障时间段(如2020-04-18至2020-04-18为首次故障)。 创建故障事件表,记录起止时间、故障类型和维护信息。 时间序列可视化 对关键传感器(TP3、Motor_current等)绘制正常与故障期间的时序图。 重采样(每5分钟均值)以减少数据量,...
