kandi X-RAY | mantichora Summary

mantichora is a Python library typically used in Architecture applications. mantichora has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. You can install using 'pip install mantichora' or download it from GitHub, PyPI.
A simple interface to multiprocessing and threading. Mantichora provides a simple interface to multiprocessing and threading. You can simply give Mantichora as many functions as you need to run. Mantichora will run them concurrently in background processes by using multiprocessing or in different threads by threading and give you the return values of the functions. The return values are sorted in the order of the functions you have originally given to Mantichora. Progress bars from atpbar can be used in the functions. The code in this package was originally developed in the sub-package concurrently of alphatwirl. The examples in this file can be also run on Jupyter Notebook.

                mantichora Key Features

                On Jupyter Notebook, the fork method is typically the best choice.

                The spawn and forkserver methods have extra restrictions, for example, on how the main module is written. The restrictions are described in the Python documentation.

                On macOS, in the fork method, errors with the message may have been in progress in another thread when fork() was called might occur. This error might be resolved if the environment variable OBJC_DISABLE_INITIALIZE_FORK_SAFETY is set YES as suggested at Stack Overflow.

                QUESTION

                What is the difference between Adapter pattern vs dependency injection in OOP?

                Asked 2022-Mar-15 at 09:27

                I have been studying Software architectures and design in my uni and I am in the design pattern section. I noticed that the adapter pattern implementation looks similarl to the dependency injection that most framework uses such as Symfony, Angular, Vue, React, that we import a class and type hint it in our constructor.

                What are their differences or is it the frameworks implementation of Adapter pattern?

                ANSWER

                Dependency injection can be used in adapter pattern. So let's go step by step. Let me show what adapter pattern and dependency injection are.

                As Wiki says about adapter pattern:

                In software engineering, the adapter pattern is a software design pattern (also known as wrapper, an alternative naming shared with the decorator pattern) that allows the interface of an existing class to be used as another interface. It is often used to make existing classes work with others without modifying their source code.

                Let's see a real life example. For example, we have a traveller who travels by car. But sometimes there are places where he cannot go by car. For example, he cannot go by car in forest. But he can go by horse in forest. However, class of Traveller does not have a way to use Horse class. So, it is a place where pattern Adapter can be used.

                So let's look how Vehicle and Tourist class look like:

                public interface IVehicle
                {
                    void Drive();
                }
                
                public class Car : IVehicle
                {
                    public void Drive()
                    {
                        Console.WriteLine("Tourist is going by car");
                    }
                }
                
                
                public class Tourist
                {
                    public void Travel(IVehicle vehicle)
                    {
                        vehicle.Drive();
                    }
                }
                

                and animal abstractions and its implementations:

                public interface IAnimal
                {
                    void Move();
                }
                
                public class Horse : IAnimal
                {
                    public void Move()
                    {
                        Console.WriteLine("Horse is going");
                    }
                }
                

                This is an adapter class from Horse to Vehicle:

                public class HorseToVehicleAdapter : IVehicle
                {
                    Horse _horse;
                    public HorseToVehicleAdapter(Horse horse)
                    {
                        _horse = horse;
                    }
                
                    public void Drive()
                    {
                        _horse.Move();
                    }
                }
                

                We can run our code like this:

                static void Main(string[] args)
                {   
                    Tourist tourist = new Tourist();
                 
                    Car auto = new Car();
                 
                    tourist.Travel(auto);
                    // tourist in forest. So he needs to ride by horse to travel further
                    Horse horse = new Horse();
                    // using adapter
                    IVehicle horseVehicle = new HorseToVehicleAdapter(horse);
                    // now tourist travels in forest
                    tourist.Travel(horseVehicle);
                }   
                
                public class Tourist
                {
                    public void Travel(IVehicle vehicle) // dependency
                    {
                        vehicle.Drive();
                    }
                }
                

                And injection is:

                IVehicle horseVehicle = new HorseToVehicleAdapter(horse);
                // now tourist travels in forest
                tourist.Travel(horseVehicle); // injection

                Install mantichora

                You can install with conda from conda-forge:.
                I will show here how to use Mantichora by simple examples. We are going use two python standard libraries time and random in an example task function. In the example task function, we are also going to use atpbar for progress bars. Import these packages and mantichora. Let us define a simple task function. The task in this function is to sleep for 0.0001 seconds as many times as the number randomly selected from between 1000 and 10000. atpbar is used to show a progress bar. The function takes two arguments: name, the label on the progress bar, and ret, the return value of the function. Note: In the multiprocessing mode, the default mode of mantichora, task functions, their arguments, and their return values need to be picklable. You can just try running this function without using Mantichora. This doesn't return immediately. It waits for the function to finish. You will see a progress bar. The return value is stored in result. Now, we run multiple tasks concurrently with Mantichora. In the example code above, mantichora is initialized with an optional argument nworkers. The nworkers specifies the number of the workers. It is 3 in the above example. The default is 4. At most as many tasks as nworkers can run concurrently. The with statement is used in the example. This ensures that mantichora properly ends the workers. You can give task functions and their arguments to mcore.run(). You can call mcore.run() as many times as you need. In the above example, mcore.run() is called with the same task function with different arguments. You can also use a different function each time. mcore.run() returns immediately; it doesn't wait for the task to finish or even to start. In each call, mcore.run() only puts a task in a queue. The workers in background processes pick up tasks from the queue and run them. The mcore.returns() waits until all tasks finish and returns their return values, which are sorted in the order of the tasks you have originally given to mcore.run(). Progress bars will be shown by atpbar. The results are sorted in the original order regardless of the order in which the tasks have finished.
