We can easily get help through the Python interpreter. If you want to know more about an object, you can call Help (object). There are also useful ways in which dir (object) displays most of the associated property names for that object, and Object._

As shown below: Abs returns the absolute value of the specified number. Acos returns the angle at which the cosine value is the specified number. Asin returns the angle at which the sine value is the specified number. Atan returns the angle of

Some time ago, a company's project required a lot of data interfaces and synchronization programs, so it encountered a log record problem, how to record the time, which do not need to be remembered. After a series of discussions on the log record
