Installed Python and Idle is not available - python

On my desktop PC. I downloaded and installed Python and was able to get the IDLE program. But on my laptop, I am getting nothing. See Image Below. Why isn't Python IDLE application not available? But when I type in "python" I am only getting the Python black command prompt box. Like this in the screenshot below.

Python IDLE is not launching

Error screenshot of 'python3 -m idlelib'[] [This is where the idle is located]Sample screen shot of the program here I recently deletd my old python program and intsalled a new one but now the Python IDLE is not launching when I click it from the start program. Also tried ruuning as a administartor. But when I open the cmd and type: "python3" I am getting the terminal. But I need to code in the python IDLE.
I have adde the image of the python IDLE, if i click that program the notepad/termiunal is not opening.
I got it solved. It seems my 1. I haven't added my path in the user variablse and 2. In system variables the path given is wrong. And yes as said by #TerryJanReedy I have installed both microsoft and python.org versions, so I deleted all files and carefully re-installed again.

Visual studio code is stuck on Select Python Interpreter

I am trying to run a jupyter notebook on my Windows machine by using WSL2 to run it in Ubuntu 20.04. It was working perfectly fine yesterday but today it's not selecting a Python Interpreter. I have tried reinstalling Ubuntu, Anaconda and Visual Studio Code.
When I run
code path_to_notebook.ipynb
It opens the window below:
visual_studio_code
After a couple seconds the box (that I've made a yellow square around) pops up. When I click in the "Select Python Interpreter" button and select the interpreter that I want (~/anaconda3/bin/python) nothing happens.
The Select Python Interpreter (red box) also stays there.
What should I do?
I've gotten around the problem by using $ jupyter notebook --no-browser in the terminal.
Unfortunately, this means that additional computer resources are required to run the notebook in my browser over a text editor. But it gets the job done.

Running python files by double click but there is IDLE mismatch

I have Python 3.7.4 installed on Windows 10. For some reasons, my "Edit with Python" option doesn't show up when I right click a Python script. So I made "idle.bat" as the default app to run Python scripts from the installed location "C:\Users\ns200\AppData\Local\Programs\Python\Python37". Now when I double click the Python Script, it runs and IDLE 3.7.1 (see picture) shows up with my code. Now when I execute the code, I get "ModuleNotFoundError" though I have all the modules installed(installed using pip3 function for IDLE 3.7.4)
If I open IDLE manually, Python 3.7.4 shell runs and I need to open the script by going to file, open ,choose the file location and IDLE 3.7.4 shows up (see picture). When I execute the script this time, it runs with no errors (as all modules are already installed for 3.7.4).
I don't know why there is an IDLE mismatch here. How can I run IDLE 3.7.4 every time after double clicking the python script with no module error?
you have selected the idle.bat inside py 3.7.1 , Select the idle.bat which is inside python 3.7.4 , your problem will be solved.
python37.4/lib/sitepackages/idlelib/Idle.bat
Approximate path above

Error running python program from Teminal but it runs fine in Pycharm

I am using python2.7 in Pycharm and program runs fine when started from Pycharm
the output from Pycharm is
I am running the same program form terminal it shows error as shown below
After some discussions, I did the following
I changed the project interpreter in python to which python2 path as shown below
Then running program from Pycharm works
but running it from terminal still have the same issue
the reason it was not working is that I was trying to import the XenAPI which is located in some other location as shown below, which pycharm is able to access by using import vkey.XenAPI but from terminal its not.
Now this problem can be solved in 2 ways
By using virtualenv , follow this tutorial
The good news is that we can directly install the XenAPI package using pip as shown below
Here is the screenshot which shows its working

Python IDLE icon appears for a second and then disappears, the IDLE doesn't start at all. - on mac

I was working on Python IDLE editor on a Mac but for some reason now every time I click on the IDLE icon, it pops up in the doc for a second and then it just disappears. The IDLE just doesn't run anymore.
In one of the recommendations I found online, it says to type /usr/local/bin/python3.6 -m idlelib, which I did in the console and it started up the Python shell, from which I can open a new file and start coding.
However, I would like to avoid doing this and be able to just start IDLE using the icon in the application folder.
I've downloaded and installed Homebrew, Pandas, PyCharm and among many others because I've seen some recommendations on installing these without complete understanding of them. I'm wondering if any of these programs altered something in the IDLE which is causing it to crash?
This is for Python 3.6 on Mac OS.
