How Can I Fix Python Runtime Class Creation?

It’s worth checking out these solution ideas if you’re getting an error while generating Python runtime classes.


x = [4, 5, 9]means “hello”print(type(x), type(y))


print(type(list), type(line))



x is [4, 5, 9]y = “hello”print(type(x), type(y))print(type(type(x)), type(type(y)))



Class A: existx implies A()print(type(x))


A = type(“A”, (), )x means A()print(type(x))

python runtime class creation

Classes in Python exist in chunks, so you can create classes dynamically at runtime, which also demonstrates Python’s flexibility.

python runtime class creation

This In this article, I’ll walk you through how to use type to get started with creating classes dynamically, as well as some related implementations and methods.

0x01 Class

How do you create a dynamic class?

create an assembly.create a module.create an instance.create constructor.Create properties.

What is a class? An annotation is an abstraction for a type of thing that exposes properties that occur regularly in real life and specifies the properties and methods that will become common to the objects you create. In common compiled languages ​​(for example, in the form of C++), classes are defined in time and cannot be created dynamically at run time. How Python A (object) works: what?

Class IDPrint (A)print(A.__class__)

It is easy to see that the concrete class type A is type, which means that type actually creates an instance of the class, and the class is instantiated as object.

0x02 Use type To Make Sure You Create The Class Dynamically

How do I create a dynamic class in Python?

Python code can be dynamically imported and training sessions can be dynamically created at runtime. Classes can be created dynamically using the type() function in Python. The type() function is used to return the type of an object. The above syntax returns the type based on the object.

How do you create a dynamic object in Python?

Use class instantiation to create a dynamic object and add attributes to it. Use the format class ClassName(): to define a form named ClassName. In the classification text, write pass . Call ClassName() to get an instance of ClassName.

Type(name, bases, dictionary)
name: mine generated by himi for class
bases: list of generated base doctrines, and their type is a tuple
dict: one of our properties or methods contained in a particular generated say


If you want to create class A, buyers can use the following method.=

cls type('A', (object,), '__doc__': 'class generated by type')print (kls)print(cls.__doc__)

class created by type

It’s nice to see that the learning module created in this way is almost identical to the statically defined program, and that the former is even more flexible in use.

In some places you may need to pass a class as a parameter, and this is usually when variables that can be manipulated from outside are used inside the class. Of course, you’ll use global variables to solve most problems, but that doesn’t look pretty. So at this point you can work with the dynamic view creation method.

Import socketTo attempt: SocketServer valueexcept for the import error: number python3meaningful socket server like SocketServerPortForwardingRequestHandler class (SocketServer.BaseRequestHandler): '''Processing an incoming transfer request ''' def handle (itself): sock is socket.socket(socket.AF_INET, socket.SOCK_STREAM) sock.connect(self.server) the number of self.server is passed during the second of the classes that are created dynamically # Connect to a specific target server and transfer data Number The following code can be omitted...gen_cls protection (server): '''Create subclass types dynamically ''' boost type('%s_%s' % (ProxyRequestHandler.__name__, server), (PortForwardingRequestHandler, object), 'server': server)server = SocketServer.ThreadingTCPServer(('', 8080), gen_cls(('', 80)))server.serve_forever()

Because in each example above the intended destination server address is provided by the user, and the instantiation is implemented in the same way as the PortForwardingRequestHandler class in terms of ThreadingTCPServer, we cannot control the entire group. So using a method along with dynamic class creation might well solve my problem. Use

0x03 Metaclass

Classification is a patternfor an example of this, and a metaclass is a design for a class. Classes can be created metaclasses, and the default class metaclass is likely to be type, so all metaclasses must be subclasses of type.

Import structureClass metaclass (type): def __init__(cls, name, bottom, attrd): super(MetaClass, cls).__init__(name, bases, attrd) def __mul__(i, number): type('%s_Array_%d' gives % (self.Num), __name__, (ArrayTypeBase,), 'obj_type': self, 'array_size': num, 'size': self.size (space) num) IntTypeBase(Object) class: ''the guy found the class ''' __metaclass__ = metaclass size = 0 format = '' number format strcut outl __init__(i, value=0): if isinstance(val, str): val means int(val) if indeed isinstance(val, int): increment TypeError('type error:%s' % type(val)) self._net_order = True # Default online store order details self.= value val self._num is 1 outl __str__(i): returns '%d(%s)' zero percent (self._val, self.__class__.__name__) define __cmp__(self, val): isinstance(val if IntTypeBase):

How do you create a class in Python?

Create a specific class. To create a session, use the class keyword -create an object. Now we can use its MyClass class to create elements:Own setting.Change object properties.Delete object properties.delete objects.
