The sentenceif __name__ == '__ main__' app.run It should not go within the function home() He must go outside.In the event that he is outside, he must go without identification, as follows:from flask import Flask app = Flask(name) @app.route('/') def home(): return 'Hello World' if name == '__ main__' app.run I recommend this wonderful explanation in which the use is explained and why of this sentence: https://es.stackoverflow.com/questions/32165/qu%C3%A9-es-if-name-main

At first I had the same problem as you and solve it in several ways depending on the project that it is developing. There's something you should take into account that is the kind of resource that is the file you want to open. For example, temporary files are saved in a folder that we all know %temp% no? Based on this principle if you order your code to find the txt in that folder, we are sure it will find it.There you can make a folder in your project that contains all the txt, json,html and always refer to that folder. Or on the other hand if your project is based only on subfolder2, focus on everything that happens with your program being executed from that folder as root.Another way is to get them through an IU to import text documents, and to have them transferred to a folder with a path that you specify, and whatever you need you have there. You could arm a txt with the default paths and your program uses these as a reference. There are many ways, everything depends on how you want to do it.That's why there is the download folder, temporary, system32, etc. And all the programs we use already know that there's what they're looking for. I hope it serves you and don't forget to score. Greetings!

Try :"html.mirrorCursorOnMatchingTag": false, And you tell me.When activated in HTML tags, if both the start labels and the end tags are "synchronized", changing one also changes the other. However, the function is disabled by default, and you explicitly execute the command On Type Rename Symbol or set the configuration editor.renameOnType in true. https://github.com/microsoft/vscode/issues/87737 https://stackoverflow.com/a/59394433/4717133

If you can, the command to use is the following:dotnet new web With this command you have an empty ASP.NET Core project.Reference: https://docs.microsoft.com/en-us/dotnet/core/tools/dotnet-new

Use this command: sudo pip install python-dotenvNormally this error is usually produced because no modules or files are missing to manage the environments, the module python-dotenv Take care of it.

Where to make the subscription to your promise add the catch of error example: this.myRequest().subscribe(response=>{ },error=>{ //en esta variable queda tu mensaje error.message; }) }To show the alert develops a popup or uses the windows alert or downloads a package for this like Angular material or Angular 2 Toasty or bootstrap, packages that already have an alert manager just need to invoke it.

By default it is configured with alt+click but you can change it in the menu selection - Use Ctrl+Click for Multi-Cursor https://code.visualstudio.com/docs/editor/codebasics#_multiple-selections-multicursor

In this case you must use the route as follows.<img src="./img/brand.jpg" alt="logo">

When you run your code what you really do is tell VSCode to use the built-in terminal to run your code, in this case use Microsoft PowerShell.The first white message you see is power shell, you can presioanr win+R and write powershell To invoke the console and you will see every time you invoke the console you get the same message.VSCode does this so he can call the Python interpreter so he can run your code. What you see in blue letters are 3 code executions so you can run your code, the first one calls the python interpreter and that's why it ends in /python.exe; the second is responsible for calling the VSCode extension so you can debug things on the IDE and the third finally runs your code that is saved in the file app.py.These are not messages, but they are the way VSCode executes your code, they are not optional. A simple way to avoid seeing them would be to import the operating system module and clean the screen, then when VSCode executes the commands and enters your code erase what is written on the console, you would occupy these two code lines at the start of your file app.py:from os import system system('clear') The first imports the module to use the terminal, use it with the other imports of modules (the ones that say import) and if you don't have any imports, make sure it's the first line in your code.The second line cleans the console, places it at the beginning of your code, before anything else is executed.The only bad thing that could happen is that you can't see a warning/mistake of the interpreter or VSCode extension by trying to run your code, as bse will erase the warning message on the console. Although it is unlikely because if the console is deleted it is because your code is already being executed.Good luck in your programming!

As they comment, you need to install psycopg2, the package that Python uses to connect with Postgres. You can run. pip3 install psycopg2 for this.If you are in a Linux environment, you must have the development tools installed (build-essential in Ubuntu, "Developer Tools" group in Fedora) and libpq-dev so that Python can properly install the package.

As the league says is a permit problem, everything seems to indicate that vscode uses powershell for its terminal.I solved it by running the following command to give you permissions:Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted bazel version Build label: 2.1.0Build target: bazel-out/x64_windows-opt/bin/src/main/java/com/google/devtools/build/lib/bazel/BazelServer_deploy.jarBuild time: Fri Feb 7 13:02:33 2020 (1581080553)Build timestamp: 1581080553 Build timestamp as int: 1581080553

The removal of c++ validation is in a hidden folder, on the route where you are compiling your file, called .vscode which contains a file settings.json with temporary settings (other than general adjustments), are specifically matched for this case of c++ this:{ "files.associations": { "string": "cpp", "iosfwd": "cpp" }, "C_Cpp.errorSquiggles": "Disabled" } Just change the "Disabled" for "Enabled" and ready. Another option is to remove that temporary settings folder and work equally.

Since I found the solution, I'll leave it in case it serves someone. The most "easy" I found is to include in the main the source file as if it were a library more only than with the quotation marks (such as the header). Thus, if you have the "Code Runner" extension and enabled to execute it on the terminal you should run without any problem.Investigating a little more and moving configurations I came to another conclusion that I like a little more since the .c is not included in the main that way, as against it we have to do a few more steps.We have to create a "workspace" or "workspace", basically a folder. It can be done by hand, but I recommend using Visual tool. That's why we have to give in Archive - 2005 New window - 2005 Add work area... In this way we should have something like this: From there on we have the option to create files by then we should have something like this: Then pressing the F1 key we should be deployed a window where we can write. There we will put "task" or "task" in Spanish and select the first option. Then we will give in "C/C++: gcc.exe build active file". Once this has been done, we will be created a .json file, here we have to do 2 things.To do it a little more intuitive (let's see where) we could put "build" where it says "label:", so that this way remains: "label": "build", If that's not done, nothing happens, but I say, to be a little more ordained is better to do it.We'll also have to add our .c file to the "args" part, below "${file}",. Such that the whole .json will remain in this way: I use MinGW and it is predetermined, if you do not, you have to modify the route.And ready, then we would have to go to the main, press the keys "Ctrl + Shift + B" and we will be deployed a window containing the "build" option (that's what we change in "label"). We give it there and it would generate us in the folder of the beginning a .exe. It should be clear that you can't use the CodeRunner in this way but so we would remove the "functions.c" from the main leaving only "functions.h".I hope it will help you and work!

A possible solution is to configure the python installation path within VScode. Press (CTRL + ,) then go to Workspace/Extensions/pylint and change the route where the Python installation is located.

Everything was well set (JDK, JRE, PATH variables, etc.), the problem was that the extension JAR Builder of VSCode is in development phase and still cannot generate .jar files from a project that works with external libraries and images.

For the computer it is more difficult to debug and get all the events from the cell phone and pass the information on a cable instead of being an emulator, but if you want to get more information when you run your app, you have at your disposal the internal debugger of the VS code with F5/Debug -> Start Debugging that you have breakpoints, all the battery functions done up to the time of the breakpoint, review variables, etc as you have the https://ciberninjas.com/flutter-dart-devtools-inspector/ of Flutter, which in my opinion helps enormously more than seeing events on console. And you can open it from the taskbar you have to stop, advance, restart the execution, appears as a magnifying glass with the Flutter logo inside.I hope I helped you with your doubt. Greetings

Assuming that your dataframe is, for example, the following:df = pd.DataFrame( data={ "year": [2018, 2018, 2019, 2019, 2019, 2019, 2020], "country": ["ES", "ES", "DE", "DE", "UK", "DE", "UK"], "title": ["A", "B", "A", "D", "C", "C", "C"], } ) df It would be like this: year country title 0 2018 ES A 1 2018 ES B 2 2019 DE A 3 2019 DE D 4 2019 UK C 5 2019 DE C 6 2020 UK C To count the number of values title (or number of rows) by country and year, we do the following:df2 = pd.DataFrame(df.groupby(["country", "year"])["title"].count()) df2 It would be like this: title country year DE 2019 3 ES 2018 2 UK 2019 1 2020 1 To see the data better, we pivot df2:df3 = df2.pivot_table(values="title", index=["country"], columns=["year"], fill_value=0) df3 It would be like this:year 2018 2019 2020 country DE 0 3 0 ES 2 0 0 UK 0 1 1 To count the number of values title (or number of rows) per country, we do the following:df4 = pd.DataFrame(df.groupby("country")["title"].count()) df4 It would be like this: title country DE 3 ES 2 UK 2 Finally, to count the number of values title (or number of rows) per year, we do the following:df5 = pd.DataFrame(df.groupby("year")["title"].count()) df5 It would be like this: title year 2018 2 2019 4 2020 1

The month if the user is not going to insert the user, you want the program to get it, then you should include the following:#include <time.h> And in your code to declare the variable month do the followingtime_t ahora; //Obtiene la fecha actual del sistema time(&ahora); //Se convierte a una estructura tipo calendario para poder obtener todas las variables struct tm *local = localtime(&ahora); //Seleccionamos el mes de la estructura y tm_mon nos devuelve un número entre 0 y 11 por lo tanto le sumamos 1 int mes = local->tm_mon +1; This code I got from this website, which is in English I don't know if it's helpful for other things related to the date. https://www.techiedelight.com/print-current-date-and-time-in-c/ I hope it's help.

this happens to return the value of the class rectángulo() in the wrong way: At the time of printing the area displays the following message El área es <__main__.calculo object at 0x000001B442E1D888>. However, the code does not declare the time when you return the value in string so python will return by default with the method repr() which serves to return a printed representation of the object in itself (as seen in the message with its hexadecimal value).To fix this you have to declare your second function as __str__to return the value as a string by remaining the code as follows:class calculo: def __init__(self, base, altura): self.base = base self.altura = altura def __str__(self): return str(self.base * self.altura) base = int(input("proporcione la base : ")) altura = int(input("proporcione la altura : ")) rectangulo = calculo(base, altura) print("el area es", rectangulo)

A few months ago, my laptop passed itself, now to my PC with the mingw32 compiler, but look at it was cleaning up some files and changing the name of the main folder without removing it from the Path before. Then I went to the path and adjusted the name and Boom passed me that mistake and I got into the picture in English and Spanish and nothing.A while ago I was learning assembler with a book from Randall hyde and he has a page where he has an assembler for his language and when he downloads it without adjusting it to the path it gave me the same mistake but that was on my laptop it gives me the suspicion that it is for that corrupt file that made me something in path because I did the same with my PC and now gives me that mistake.can be that file that hurts something in path orWhen I made the adjustment, it damages some file in the path that the compiler needs to walk well. Greetings if you've already solved please let me know
