First, what is called serialization The process of converting an original dictionary, list, and other content into a string is called serialization.Second, the purpose of serialization1. Persist the custom object in some form of storage;2.

I. INTRODUCTIONThe module supports the logical organization of Python code.When the code is quite large, we'd better split the code into organized pieces of code, provided that they interact with each other.The operation of attaching attributes from

The design principles behind the new date class and the time class: Non-variable class The date class is a mutable class before java8. When we use it in a multithreaded environment, programmers should confirm the thread safety of the date object.

one, Time ()-- returns the current Unix time Stamp$nextWeek = time () + (7 * 24 * 60 * 60);Echo ' Next Week: '. Date (' y-m-d ', $nextWeek). " \ n ";Second, mktime ( hours/ minute/ sec/ month/ day/ year)-- get a date for Unix time Stampecho Date ("M-

In Python, there are three processing libraries for time, dates, and calendar, in which DateTime has datetime.date, Datetime.time, and datetime.datetime three classes. Time can be divided into time stamp, local time and UTC time (World Standard Time)

Using serial communication, use the following script at the standby to detect heartbeat signal from the host, once the number of not accepted more than the specified number, the standby machine think the host down machine, automatically set as the

One: Introduction In JDK1.8, Map has new methods, some of which are designed to simplify code, such as foreach, and other methods to prevent null and to make the code more rigorous. II: Map Public interface Map { //If key exists, ignore put

Oracle may also be aware of the lack of Java processing dates, so new localdate and localtime interfaces are added to JAVA8. It is well known that the month of Java.util.Date is from the beginning of 0 ~0 representative January, 1 represents

This section describes how the Python application processes time and date. The conversion date format is the most commonly used feature.(1) Get timestamp:Python provides a time and calendar module that can be used to format dates and times.The

Personally think the second kind is more practical, but also the most commonly used ~However, when the calculation algorithm time-consuming, do not forget second, not as long as the milliseconds to reduce, otherwise negative, if the algorithm time
