I just installed VSC and did a 2 line code as per the tutorial:
msg = "Hello World"
print(msg)
when running the code, the following error message is displayed:
The terminal process terminated with exit code: {0}
If I click on the terminal menu, and then new terminal, it briefly appears and vanishes with same error message.
Try running the program by pushing the green arrow in Visual Studio Code. I think what you’re seeing is that the code completes and the terminal closes. It’s not waiting for you to do anything, so it’s finished.
Assuming you’re in Windows, the easiest way to get around this is to run the code within the Visual Studio itself.
Another handy way to use PowerShell. Open PowerShell. Navigate to the directory were you have saved the program and type “python yourfilename.py”. The program will still end quickly, but you will be able to see what it printed.
Finally, you can use Python IDLE. IDLE is an IDE, like VS Code, but specifically for Python. You can open your program with IDLE and it will display the results in a similar way that it would appear in PowerShell.
There are a lot of different options. It’s confusing when you’re first trying to get your bearings. You’ll find something that feels good for you.

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.
I was using a different IDE for running Python scripts, but I would like to switch over to Visual Studio. When I try testing simple scripts that work in the simple IDE, I can't figure out how to get my output to show correctly. I have tried running the debugger, pressing CTRL+F5, and pressing CTRL+F5 then CTRL+d, but all that happens is that a blank console pups up, and the cursor blinks actively.
I have run out of ways to rephrase this issue to get something helpful to show up in both Google search results and in StackOverflow. The main results I get are about antivirus software (thoroughly investigated, not the problem here) and articles about beginning Python in VS. How do I get my Python programs to show output correctly? And also am I using incorrect terminology?
What happens when I hit Ctrl+F5
Have you already gone through the Installation, Quickstarts and Tutorials here:
https://learn.microsoft.com/en-us/visualstudio/python/overview-of-python-tools-for-visual-studio
Make sure the simple hello_world.py file with one line works:
print("Hello World")
If you still have problems, it may be that Visual Studio does not realize you have Python installed (i.e. if python is not in your path variables).
For example, running the following line of code:
print("Hello, world! My name is Enkouyami")
Only outputs this:
Process finished with exit code 0
The only way to get it to display that text is to go to the python console.
My AV Program was pausing the installer and the Pycharm application, asking me if I want to allow the program to perform certain actions. Even though I allowed it, it messed up my Pycharm setup. Reinstalling Pycharm fixed the problem.
Greetings dear community,
I am currently using Sublime Text 2 (Unregistered) as my coding agent. And there is a strange behavior i noticed lately. When i am running a code in sublime text(Through build, with CTRL-B), if a code needs long time to run, like an infinite loop, I try to cancel the build(I specified CTRL-SHIFT-B to cancel build), sublime text shows me a message that build is cancelled
[Cancelled]
like so. In regular command line this means python program is no longer running. As I think it should be the same in sublime text, however, it is not. As longer i keep trying to cancel than build again, more and more python.exe keeps showing in the task manager. I can have like 10 python.exe running behind if I don't end process manually through task manager. Can somebody explain this behavior to me please ? And the reason behind it, can I prevent it ?
By the way, I tested the Python IDLE, and command prompt before asking so i could provide more information
Python IDLE shows same behavior and keeps python exe's running after cancelling.
Command prompt stops the process with no problem.
I am using python2 in a windows 8.1 system.
Thanks in advance for your time.
I'm working on a small game and, in the interest of full disclosure, I've learned some other languages before but this is only my second day learning Python.
What I was trying to do was simple enough: I was trying to generate a random integer between two integer values (e.g. random(a,b)). I looked around to see if there was an existing function that I could use, and I found information about a function called "randint". So I added a line of code to my program that looked something like:
value = randint(1,15)
I received an error that randint was undefined. So then I looked further and saw someone state that I needed to import the random library using the following line of code:
import random
The moment I refreshed (F5) IDLE crashed. So then I figured "welp, that was wrong" and I went to open IDLE and make the change. I was able to open IDLE, but I can't open the file. In fact, I can't open any of the (three) files that I've made. I opened the file in Notepad++ and removed the offending lines (both randint and import random), but IDLE still crashes whenever I try to open a file. I rebooted my laptop for lack of a better idea, but there was no change in behavior.
Details: Windows 7 x64 w/ all updates, Python 3.2.3.
...help? Also, what did I do? :-/
Received a solution from another forum:
"If you want to try diagnosing the problem, run the Python command line and then enter the line:
from idlelib import idle
That will launch idle, and you should get a traceback in the command prompt if something goes wrong."
When I did this it opened IDLE and produced an error (displayed in terminal) when I tried to open the file. Rather than crashing, I received a prompt (pop-up, not in terminal) to save the file. I found this odd because I had just opened it and hadn't made any changes. I let it save the file and then success! Now I can use IDLE to open any of my files again. Hope this helps someone else who encounters this issue :)
I'm not sure if this is helpful, but based on my experience, IDLE was never reliable enough for me. Practice using the command-line Python instead.
Go to the command prompt by running cmd
cd into your file's directory
type python yourfilename.py
