When you run a python script from terminal and before it completes running of you control + c it, it gives a traceback where the code was currently running. Is it possible to see which part of a code is running without terminating it.
in pycharm, you can debug by selecting code areas that you want to work, and by pressing next and next, you'll see how does program running it, without terminating it.
You can do this in PyCharm using the debugging facility. It allows you to step through your code line by line, running each line as you pass it. You can see what variables have been assigned etc. Very helpful for debugging!

How can I change the output format in Pycharm to make it similar to the one that R-Studio has - line of code - corresponding output
line of code - corresponding output
line of code - corresponding output
etc..
The reason your pycharm output doesn't look the same is because it's only executing the code and then exiting the interpreter. Whereas it would appear that R-Studio is executing code in terminal mode; which keeps the interpreter running allowing you to execute code on the fly.
Pycharm CAN be run in a similar fashion but it's likely not exactly what you're looking for.
If you put a breakpoint in your code and execute your script in debug it will pause at your breakpoint and then allow you to execute code on the fly in the console.
My current (PyCharm based) debugging workflow is to run a program in debug mode. When I run into an error, I fix it, and restart the program from the beginning.
Is it possible to save re-running the healthy part of the program by moving the program back by one step, fix the issue, and continue the program?
Is there a general way to do this, and one specific for PyCharm?
[edit:]
this is related but not similar to Is there "Edit and Continue" in PyCharm? Reload code into running program like in Eclipse / PyDev? , as there the author anticipates halts the program before an error occurs. here, i consider an error state
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.

Can't send input to running program in Sublime Text
(5 answers)
Closed 7 months ago.
I wrote a factorial program in Sublime text editor. After executing the program using the shortcut key Ctrl + B only the first print statement is getting executed. However, I tried using the shortcut key Ctrl + Shift + B and the result is the same.
The problem is that proper execution is not achieved and I am unable to figure out the issue which is causing the problem.
Here is an image of the above-mentioned situation. As you can clearly see that I am following the conventions to execute the code. However, only the first line is executed.
Although I tried the same code in default Python IDLE I got the result. As such I don't think the code is wrong. Is it due to some IDE issue or have I not installed the sublime text editor properly.
Your code isn't wrong; the problem is that Sublime doesn't support interacting with a running program without extra work. Although it connects stdout and stderr to the output panel so that output your program generates can be displayed, it doesn't connect stdin to anything.
What you see is yourself typing 34 into the output panel, but your program doesn't see that and just sits in the background forever waiting for input that you can't provide until you kill it.
In order to run an interactive program like this from Sublime, you need to create your own sublime-build file that either opens an external terminal and runs the program there, or one that utilizes a package such as Terminus to open a terminal within Sublime and run the program there. Both of those require you to know what command you need to run in the terminal in order to run your program in order to set up the build.
An example of using Terminus for this task (using C and not Python, so you'd need to adapt it) can be found in this video on buffering and interactive builds in Sublime (disclaimer, I'm the author).
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.
