VS Code had a problem in running the code

I tried to run a python program in VS Code. But my program didn't run. The terminal opened and a weird arrow was there in the terminal. This is the screenshot of that.
This is the weird arrow and the program is not running. Any ideas why this is happening and how to fix it?
Thanks in advance.

Firstly, the arrows are included in the default python IDE means that VScode ran the command to execute your code. Give your pc a restart. Now, let us check if python is working or not or VS code is having some trouble. Type the following command in cmd to execute the code-
python "$PATH"
Rember to replace $PATH to the path of the file i.e where your file is stored. For eg. I've my python files stored in D drive in a python folder, so I'll use-
python "D:\Python\Hello.py"
If this works, python is working fine and if not, try reinstalling python and check the box which says Add python to Path or Environment variables. Then open VS code try to run the program again. But click the button only once and be patient because clicking it multiple times causes execute the same command again and cause a problem. It's my personal experience. Wait 5 minutes. Not works. Don't worry, there's a problem with the run extension you are using. I'll recommend the Code runner by Jun han. I personally use it. Type this in the extension search box-
formulahendry.code-runner
Install it and then try again.

Kill the terminal, and retry. If not work, restart the VSCode.

Failure to run the program made by pyinstaller

I just converted .Py and successfully generated .exe file. When tried to launch,the application windows immediately closed without any error
win 10,python2.7
May I know what went wrong with the program?

you probably need to run the executable from inside a CMD.
Unless you used some kind of a UI package, simply clicking on the exe file will open a CMD window that will be closed immediately on error or when the program is finished.
To run it, open a cmd and just type the file's name (with full path).

Try with Python 3. Python 2 support has ended and recent versions of PyInstaller do not support Python 2 any more.

I also tested it with Python 3, but it didn't work again
No script responds
I made a "Hello World" script, but it did not open
Please, if you can help, it is very, very important to me
I got a project, I am currently stuck in this stage

Python Executable how to on Windows

I'm running windows
I've got a python script that works as expected when I run it from my interpreter (Anaconda, i think that's an interpreter...), but when I run it from my file manager by double clicking the script ("script.py") I see a quick black screen flash, but nothing else. I'm using the input() function, so that's not the issue.
When I try the same thing with a simple test script, which is just the print() function and the input function, the command line or terminal screen, whatever the black screen is called, displays my printed string and closes only after I press enter.
I believe my issue has to do with file paths and working directories, but I'm a noob and I don't know how to solve this. My script declares this variable:
inv_folder=r"C:\Users\domin\OneDrive\Desktop\Test Folder" #folder to look for completed recipe files
which I believe is an absolute filepath. I then loop through the files in that folder and open and read them
for filename in os.listdir(inv_folder):
Main goal is to send my script to someone else's computer, and allow them to run it simply by double clicking on the file. Trying to do that on my computer and failing

Doubleclicking the .py file in Windows will generally run the file. In your case, if all your script is doing is looking for a directory and looping through files in it, it is quite possible that the script is working correctly, but that it is closing immediately upon completing the script.
E.g. if you have the following python file hello.py with the single line of code.
print("hello world")
If you doubleclick hello.py, you will only see a black window flash for a second, as the program runs and exits.
To check whether your code is working correctly or not, you are best to navigate to that folder in your command prompt and run the program within the command prompt. E.g. typing "hello.py" in the right folder will then show the correct output in the console.
Try running it in the console first, seeing if the code is giving any errors, and then working from there. But the behaviour you are describing is basically standard Windows behaviour and not necessarily an error.
If you need to pause the window after running, please see the following StackOverflow question and answers about "Python Equivalent to System('PAUSE')"

Have you considered to compile it?
You can compile it easily with pyinstaller and this command:
C:\<path_to_python>\Scripts\pyinstaller.exe --onefile -n <your script name> <your script path>
Of course replace the <> with the relevant paths for you.

How to open a tkinter script that calls a different script within the same directory?

Sorry for the confusing question. I am working on a GUI and backend of a program that takes information from the gmail-api makes it into a text file. The back end and GUI(Tkinter) are working perfectly but through the python3 shell. When I just click on the python script within the directory a black command prompt appears and then disappears.
When I click on a prototype I have of the GUI that does not call another script but a text file, the GUI pops up perfectly.
This is after I used pyinstaller to make it an executable.
My end goal is to make the whole GUI and back end an executable file.
I was wondering if anyone knows why this happens. I think it might be because of it having to call another script...but I am not sure.
Sorry again for the confusing question and wordy explanation.

You want to go to the terminal after you've intalled pyinstaller and run this command:
pyinstaller --onefile --noconsole yourtkinter.py
Explanation:
--onefile : Optional here, more comfortable for tiny tkinter projects.
--noconsole : Will solve your command line opening issue.

Windows executeable created with Py2exe won't run on another computer

I created an executeable of my Python script. Everything works just fine on my first computer but when I try to run this very same executeable in another computer, it wont work. When I try to run my executeable I see that computer tries to open it, because command prompt window appears but nothing else happens, prompt window will disappear. Problem can't be in computer, because both my computers are 32 bit Windows machines and I have done similar things before but this kind of error I see first time.
I don't want to post my code at first, because it is more than 500 lines long. But I will give some more specifications about my problem.
This program I create is actually advanced version of application i made earlier. And earlier version worked fine in both of my computers. This advanced version, I am working on now, is developed into many standalone Python scripts unlike first one which was only one script. Could this be the source of my problem? Should I do something different when running setup.py now when I have many scripts?
And then there is third version of my application. Executeable of it runs fine on computer where I created it, but in my second computer it wont run either. But this time I get error too. When I run this program in my second computer the opening screen of aplication appears, there are some buttons which are meant to open other scripts, when they are clicked on. But when I click them I get following error: The system cannot find the path specified.
If someone is willing to look into my long code, then I am willing to share it. But again I dont want to post it here.
I am using Python 2.7 and windows 7 in my first computer and windows XP on my second computer.
I would be very grateful if someone points me right direction which helps me to solve my problem.
