输出了
object(myNamespace\MyClass)#2 (0) { }
没看明白这个是干嘛的?
------解决方案--------------------
new static new self 都是实例化当前类, 但是new static只有代码所在的类,就是子类如果没有重写的话那么实例化的就是父类。 而new self就是严格的当前类

The reason for the error is NameResolutionError(self.host,self,e)frome, which is an exception type in the urllib3 library. The reason for this error is that DNS resolution failed, that is, the host name or IP address attempted to be resolved cannot be found. This may be caused by the entered URL address being incorrect or the DNS server being temporarily unavailable. How to solve this error There may be several ways to solve this error: Check whether the entered URL address is correct and make sure it is accessible Make sure the DNS server is available, you can try using the "ping" command on the command line to test whether the DNS server is available Try accessing the website using the IP address instead of the hostname if behind a proxy

Before introducing the usage of self in Python, let’s first introduce the classes and instances in Python. We know that the most important concepts of object-oriented are classes and instances. Classes are abstract templates, such as abstract things like students. , can be represented by a Student class. Instances are specific "objects" created based on classes. Each object inherits the same methods from the class, but its data may be different. 1. Take the Student class as an example. In Python, the class is defined as follows: classStudent(object):pass(Object) indicates which class the class inherits from. The Object class is all

The role and usage of static in C language: 1. Variable scope; 2. Life cycle; 3. Internal function; 4. Modify global variables; 5. Modify function; 6. Other uses; Detailed introduction: 1. Variable scope, when If there is the static keyword before a variable, then the scope of the variable is limited to the file in which it is declared. In other words, the variable is a "file-level scope", which is very useful for preventing the "duplicate definition" problem of variables; 2. Life cycle, static variables are initialized once when the program starts executing, and destroyed when the program ends, etc.

1. static Please look at the following program first: publicclassHello{publicstaticvoidmain(String[]args){//(1)System.out.println("Hello, world!");//(2)}} Have seen this Segment programs are familiar to most people who have studied Java. Even if you have not learned Java but have learned other high-level languages, such as C, you should be able to understand the meaning of this code. It simply outputs "Hello, world" and has no other use. However, it shows the main purpose of the static keyword.

Practical application scenarios and usage skills of the static keyword in C language 1. Overview static is a keyword in C language, used to modify variables and functions. Its function is to change its life cycle and visibility during program running, making variables and functions static. This article will introduce the actual application scenarios and usage techniques of the static keyword, and illustrate it through specific code examples. 2. Static variables extend the life cycle of variables. Using the static keyword to modify local variables can extend their life cycle.

Differences: 1. Make can only be used to allocate and initialize data of types slice, map, and chan; while new can allocate any type of data. 2. New allocation returns a pointer, which is the type "*Type"; while make returns a reference, which is Type. 3. The space allocated by new will be cleared; after make allocates the space, it will be initialized.

Modifier abstract (abstract) 1. Abstract can modify a class (1) The class modified by abstract is called an abstract class (2) Syntax: abstractclass class name {} (3) Features: Abstract classes cannot create objects separately, but they can be declared Reference the abstract class name reference name; (4) Abstract classes can define member variables and member methods (5) Abstract classes have constructors. When used to create subclass objects, jvm creates a parent class object by default; abstract constructor methods apply Applied when jvm creates parent class object. 2. Abstract can modify methods (1) The method modified by asbtract is called an abstract method (2) Syntax: access modifier abstract return value

The functions of static: 1. Variables; 2. Methods; 3. Classes; 4. Other uses; 5. Multi-threaded environment; 6. Performance optimization; 7. Singleton mode; 8. Constants; 9. Local variables; 10. Memory Layout optimization; 11. Avoid repeated initialization; 12. Use in functions. Detailed introduction: 1. Variables, static variables. When a variable is declared as static, it belongs to the class level, not the instance level, which means that no matter how many objects are created, only one static variable exists, and all objects share this Static variables and so on.
