Issue with VS Code and python preview extension - python

im new using VS Code, and im not able to get to work a plugin called "Python preview"
Im using Ubuntu 20.04 and VS code 1.46.1.
When i try to "open preview on the side" of any .py file, its tries to open but close suddenly raising always this issue:
"Failed to launch the Python Process, please validate the path 'python'"
I suspect that this might happen with other extensions.
Any idea?

I had the same problem. Follow these steps and it will be OK:

reload the vs code
try python preview in vs code

my code is not showing is the terminal and there is no error

I was trying to run a code in vs code but the code didn't run and there is no error showing in the terminal. I made a new file and then tried to run a "Hello World!" but the code didn't run too. I uninstalled and re-installed vs code (three times) but that didn't work.
And when I say that there is no error showing I mean it. whenever I run the code nothing happens and vs code doesn't even give a hint or a sign that the code got executed or not.
First, you should understand that vscode is a lightweight editing
tool. If you want to run python files, first make sure you have
installed python correctly. You can enter command python --version
in the terminal to confirm it.
Then, please install python extension in the vscode extension store.
Then use shortcuts "Ctrl+Shift+P" and type "Python: Select
Interpreter" to choose the python interpreter.
Finally, creat *.py file and run it.

Requests_html render() returning WinError 14001 on VSCode

I'm working on a web scraping project using Python. I'm using the requests_html library. My problem is identical to one that someone else had . When I run
r.html.render()
I get an error that says
OSError: [WinError 14001] The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail`.
On the other thread I linked, someone said that the issue is with chromium and that I should reinstall requests & Python. I did a reinstallation of Python (both from VSCode and from the Python website) as well as reinstalling requests. However, I am still receiving this error when trying to run my code. Does anyone have any advice on what I can do?
Go to command prompt as admin and run sxstrace.exe.
sxstrace.exe Trace -logfile:tracefile.etl
run your program until error occurs then go to the cmd window and press Enter key.
Then run
sxstrace.exe Parse -logfile:tracefile.etl -outfile:tracefile.txt
this will output a file into your System32 directory. Find it and post contents of the .txt file here. It should contain information on what is wrong.
I got this error after initially installing python via the Microsoft App store. I uninstalled that instance of python and reinstalled it using an installer from python.org and that resolved the error. There was one error on the very first run of my code when the initial chromium download was triggered by the call to render() but after that it worked.

"Python extension loading" Issue inside VS Code attached containers

When trying to attach to a docker container using VS Code and execute python code in a Jupyter notebook file, the python extension gave me "python extension loading" and it also failed to run any python code. I did however find a fix by turning off telemetry but then that started to causes excessive CPU usage (100%). The chrome Jupyter notebook works fine, however, an IDE like VS Code would help a lot. If anybody has a fix for this please let me know. Thanks!

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.

Visual Studio code Debugger won’t start on my Python

I have a very simple program written but when I click start on the Visual Studio debugger nothing happens! Sorry total noob here. Working with python 3.6.5 32 bit for Windows. The program runs from the terminal just fine.
def main():
print ("hello world!")
if __name__ == "__main__":
main()
I've just come across the same issue in VS Code (I think) in that I can run a one line python file from the terminal and it will work as expected:
python HelloWorld.py
However when I try to run it in the debugger nothing happens other than the Debug toolbar briefly appearing. I got more suspicious having put a junk console entry in launch.json and it didn't cause any errors.
My problem was that the training instructions I'm following told me to set the following for my workspace settings so it would use the specific python executable in my virtual environment:
{
"python.pythonPath": "env\\Scripts\\python"
}
Once I changed the last part of that path to python.exe, everything worked as expected. Hopefully you can try a similar resolution in Visual Studio.
I had the same issue with all ide programs not just VS.code the problem is when installing python you didn't allow different ide environments to use python and its only executable from windows terminal what you need to do is delete python and VS code completely then again install python 3.x and in the first page of installation check the "Add python to path" box its a must if you want to use something other than windows terminal to code. after reinstalling the python now reset your device and install VS code again and that's it. problem solved
