For example:import sys from PyQt5 import QtWidgets, QtGui, QtCore class Window(QtWidgets.QWidget): def init(self): super().init() self.labelOld = '' self.label = QtWidgets.QLabel() self.lineEdit = QtWidgets.QLineEdit() button = QtWidgets.QPushButton('lineEdit -> label', clicked=self.onClicked) box = QtWidgets.QGridLayout(self) box.addWidget(self.label, 0, 0, 1, 2) box.addWidget(self.lineEdit, 1, 0) box.addWidget(button, 1, 1) self._timer = QtCore.QTimer(self, interval=300) self._timer.timeout.connect(self.nevLabel) self._timer.start() def onClicked(self): self.label.setText(self.lineEdit.text()) def nevLabel(self): if self.labelOld != self.label.text(): self.labelOld = self.label.text() msg = QtWidgets.QMessageBox.information(self, 'Сообщение', 'Изменилось значение QLable!' ) if name == 'main': app = QtWidgets.QApplication(sys.argv) w = Window() w.show() sys.exit(app.exec_())

Because you're editing the wrong variable with the loop for. I don't understand very well the functioning of the loop for, but I know something's wrong with it, because it's making a binary object. For the loop, I can help you with that...

I already knew what my mistake was, and I needed to indicate that I wanted the result to show it to me entirely. num=int(input('Ingrese un numero ')) if 100 <= num <= 999 or -999 <= num <= -100: if num < 0: print('El numero ingresado es negativo') d1=num//100 ---> era solo agregar otro '/' aqui d2=num%100//10 ----> y aqui d3=num%100%10 print('El numero ingresado es de 3 digitos') print(d1) print(d2) print(d3)

I leave the resolution here is my question for anyone who has the same doubt as me. What happened to me was to have called the same name than my variable the program was considering that as a variable so it was confusing. /** * @Assert\True(message = "Erro! Verifique as horas. Data inical não pode ser maior que a data final.") */ public function isHorasCheck() { return ($this->horainicio < $this->horafim); } What I added, but that wasn't in the question, I thought it would be better this way. /** * @Assert\True(message = "Erro! Verifique as horas. Data inical não pode ser maior que a data final.") */ public function isHorasCheck() { if ($this->horafim === null){ return true; } if ($this->horainicio === null){ return false; } else{ return ($this->horainicio < $this->horafim); } } One way or another works now is just to see what's best for you.

to propose a solution For the USER model to create a field read_news where the ID of the news will be stored, it is important that the mass be sorted, that is to say, at worst, a log(n)-time is needed.There's a bisect module.from bisect import bisect The worst check will take logn - time where n is the length of the mass

I have managed to send the data from the views on the properties Movies and Books.Since from what I have seen, in view only the model arrives when you receive the data from the controller and then that is interpreted as HTML and that only the data from the form is sent to the controller, I have solved it as follows:To the Person entity, I added the properties MoviesRequest and BooksRequest type string, because here two arrays will arrive in JSON format that I will parse to the Movies and Books properties respectively remaining the Person class as follows:public class Person { public string Name { get; set; } public string LastName { get; set; } public string Data3 { get; set; } public string Data4 { get; set; } public List<Movie> Movies { get; set; } public List<Book> Books { get; set; } public string MoviesRequest { get; set; } public string BooksRequest { get; set; } } On the other hand, in the Father view I have added two hidden fields that refer to those two new properties:@Html.HiddenFor(m=> m.MoviesRequest, new { id = "hiddenMovies" }) @Html.HiddenFor(m=> m.BooksRequest, new { id = "hiddenBooks" }) Partial view _Books I have in javascript a global variable libroswhich in the ready document I establish as follows:libros = @Html.Raw(Json.Encode(Model)); And every time I modify the book array, I update the hidden field, assigning it:$("#hiddenBooks").val(JSON.stringify(libros)); Same for partial view _Movies.And then, in the form post, when the call comes to the controller, what I do is to patch it to your original property this way before saving it in BD:[HttpPost] public ActionResult Create(Person person) { try { person.Books = JsonConvert.DeserializeObject<List<Books>>(person.BooksRequest); person.Movies = JsonConvert.DeserializeObject<List<Movies>>(person.MoviesRequest); // TODO: Add insert logic here return RedirectToAction("Index"); } catch { return View(); } } With this, I can edit the data as you want and in the controller I have them strongly defined.

Depending on whether you're interested in a poetry comparison or simply comparing the elements of the list as such, you can write:lst1=['мама', 'мыла', 'раму'] lst2=['мыла', 'раму','мама'] if set(lst1)==set(lst2): print("True") else: print("False") or so:if lst1==lst2: print("True") else: print("False")

Assuming your variable ventana It's where you've done Tk()You can do this:ventana.bind('<Return>', lambda e: operaciones()) ventana.bind('<KP_Enter>', lambda e: operaciones()) There are two important things:The method https://www.geeksforgeeks.org/python-binding-function-in-tkinter/ (I leave you several examples) allows you to assign events to tkinter objects, in this case we are interested in assigning it to the window so that it can detect the events no matter where the focus is.Lambda: Lambda must receive an event, so it is declared (in the variable e will be the event) and what it does is to call your method operaciones() I guess that's what you're interested in. I have bind it to two different keys, one is the keyboard enter and the other the numerical keyboard enter.I hope it serves you, in the face of any doubt here we are.

I think to check the age at the input the user would be more useful to use ranges, such as this:if edad in range(18,100) With this you check that the value of the variable edad is in the established range between parenthesis. The input that asks the age, should go out of condition, since it makes no sense to ask the age within the loop, since prior to the execution of the ifthe age variable has no value.I also recommend, as Fran has said, that you review tabulations as, like most languages, python is sensitive to them and in the example that you facilitate elif They're not aligned with the first if.Your code would remain so:clientes={} def ficha(): print ('Ha introducido la opcion añadir cliente') clientes['NIF']=input('Introduce el NIF del usuario: ') clientes['Apellido']=input('Introduce el apellido del usuario: ') clientes['Nombre']=input('Introduce el nombre del usuario: ') edad = clientes['Edad']=int(input('Introduce la edad: ')) while edad not in range(18,100): print("Edad fuera del rango") edad = clientes['Edad']=int(input('Introduce la edad: ')) if edad in range(18,100): print (clientes) break def menu(): print ('(1)' 'Anadir un cliente:') print ('(2)' 'listar clientes:') print ('(3)' 'Borrar cliente:') print ('(4)' 'Grabar datos en el fichero:') print ('(5)' 'Leer datos de fichero:') print ('(99)' 'Finalizar') while True: opcion=int(input('Introducir numero, siguiente opcion: ')) if opcion==1: ficha() elif opcion==2: print ('Ha introducido la opcion listar clientes') elif opcion==3: print ('Ha introducido la opcion borrar cliente') elif opcion==4: print ('Ha introducido la opcion grabar datos en el fichero') elif opcion==5: print ('Ha introducido la opcion leer datos del fichero') elif opcion==99: print ('Finalizado') break else: print ('Ha introducido una opcion erronea') return menu() And an example of your execution can be this:(1)Anadir un cliente: (2)listar clientes: (3)Borrar cliente: (4)Grabar datos en el fichero: (5)Leer datos de fichero: (99)Finalizar Introducir numero, siguiente opcion: 1 Ha introducido la opcion añadir cliente Introduce el NIF del usuario: 123 Introduce el apellido del usuario: Perez Introduce el nombre del usuario: Juan Introduce la edad: 10 Edad fuera del rango Introduce la edad: 15 Edad fuera del rango Introduce la edad: 20 {'NIF': '123', 'Apellido': 'Perez', 'Nombre': 'Juan', 'Edad': 20}

I did something like that, I wrote the form init method. At the time of installing the form I pass the parameters I want:form = QualquerForm(request.POST,var1='ola mundo') Now about writing the form method:class QualquerForm(forms.Form): def __init__(self,*args, **kwargs): self.var1 = kwargs.get('var1',None) super(QualquerForm, self).__init__(*args, **kwargs) So I can access in any method the passed variable like this:self.var1

Hya multiple optimizations according to my experience as a programmer several years ago. I will list them as follows:Remove all impressions: Impressions spend resources and cause the algorithm to delay more in running each instruction.Programming a cache: Because they are multiple data you can partition the file and load each pool to memory, it could work, the problem is when you need a specific data.Use thread or threads: You can create a thread for every logic thread your processor has. This you can quickly look at in the task manager, you can also get it via code. This option can be combined with the previous point, with that you can load everything in memory faster.Cloud computation: Amazon Web services offers this type of services, obviously you have to go through a box to use powerful machinesHTCondor: This allows you to use multiple machines, yes, multiple machines to run the same program, is the overkill, and it is within the distributed computer. It runs tando in windows as in linux, and its configuration is usually a bit tedious, but with this they get incredible results. Using HTCondor more multithreading you do, and more if you have multiple computers in your home or office.Now, what is not an option:Google Colab: These are CPU-level operations, the main problem is that google processors lend free for google collab are not so powerful. Comparing a single nucleus of my ryzen 5 3600 with a single nucleus of the processors of these servers is more powerful my ryzen. In addition, google solutions in this aspect are one to two nucleus at most. The strength of this tool is processing by GPU and TPU, not in CPU.GPU: The gpu/tpu is for matrix calculations, it is not to read files or anything, in fact, of the experience I have in CUDA there are no libraries that allow to load files to the branch using this type of hardware. In fact, the GPU architecture as such is not for that.

What's the problem with the picture class?class Image(...): image = models.ImageField(...) product = models.ForeignKey(to=Product, null=True, blank=True, ...) category = models.ForeignKey(to=Category, null=True, blank=True, ...) And before you keep checking that it's exactly 1 FK value not None?You can still write your @register and the method that generates this communication class based on the basic abstract class.
