Python Extension is not working in vscode bc of & command

I installed python then configured it for vscode by following docs of vscode, but they said I have to right-click on the editor after seeing a run Python in terminal. And I have to click on it.
But it only works in Powershell and when I tried to use it in cmd, then they said ----
D:\Program\Applications\C++>& D:/Compilers-Interpreters/Python38-32/python.exe d:/Program/Applications/C++/app.py
& was unexpected at this time.
D:\Program\Applications\C++>
I am using the C++ folder bc I was also trying to set up C++ by following the tutorial in vscode doc. Now can someone tell me how to fix this & problem????

This is a problem with VSCode, On the VSCode insiders it has been solved. You can wait for the next stable release of VSCode.
You can take this as a workaround for now:
Take adventage of terminal.integrated.shell.windows instead of terminal.integrated.defaultProfile.windows for now.
You can refer to here for more details.

It seems that for some reason & is being added to the beginning of your command, which makes the command invalid.
Upon testing, I actually am running into the same issue, suggesting it could be an issue with VS Code and Python. I would recommend using the debugger to run your program, which still seems to work. Just press F5 and select Python File: Debug the currently active Python file. Another way to do this is to define the launch.json configuration to automatically launch upon pressing F5.

iPython automatically at launch in Visual Studio Code on Os X

I would like that iPython run automatically when I launch VSC instead of typing ipython and press enter in the terminal. The answer here How to set ipython/jupyter as the default python terminal for vscode? doesn't work as it is for windows but it shouldn't be really different. Also, is there something similar to the 'Execute' button in Spyder instead of typing %run filename ? Thanks !

I presume you mean you want to run the "Python Interactive Window" and not just an iPython console on startup
There is currently no way to run it on startup. At least no way without writing another extension that would run a command when opening a workspace. It would be simple for us to add one though. Probably a workspace setting. Can you log an issue here:
https://github.com/Microsoft/vscode-python/issues/new
For you second question, 'Execute' in spyder, we have 'Run Current File in Python Interactive Window'. This works on any python file. You can get to it through the context menu on a file or through the command palette.

Sadly the nice workflow of spyder is not provided by any official extension at the moment (as far as I know).
But you can implement the basics easily on your own by writing an extension. Even with no experience in TypeScript you can quickly build an extension which starts an IPython console as soon as you open a python file. I also managed to execute a startup script which implements the runfile method. VS Code also allows keybindings for your functions, so that you can almost work like you can with spyder.
Spyder modified the IPython terminal quite a bit though, so it won't feel exactly the same. But after all, everything there is open source so you could implement it yourself, which is what I'm trying to do in my free time.

In Visual Studio Code, how do I load my python code to a read-print-eval loop?

I am teaching a class that uses VScode.
I am used to teaching using IDLE, and it is very nice for the students to be able to call their defined functions and run snippets of code in a python terminal, for debugging purposes.
In VScode, they I have been unable to do the same in a satisfactory way.
Option1: I can select all code, right click and run selection/line on terminal. This works for small snippets, but I cannot do it for the whole file (even after selecting the whole file with ctrl-A). On linux, this works, but on windows, it does not, unfortunately (and my students use windows)
Option2: I can use the debug console. This requires adding a breakpoint in one of the last lines of the file, and does not offer tab completion. It works, but is less convenient than IDLE.
Option 3: I can also add the commands to run to the bottom of the file (which is a least preferred alternative, given that is forgoes the interativity of the read-print-eval loop).
Is there any better solution? Installing a VScode extension would not be a problem.

Visual Code is just a text editor like your traditional notepad. to run and debug any kind program you need to install the particular extension for the programming language.
In your case you are using python so you need to install the extension of it. the best one is the "Python" which is developed by microsoft itself. go to your extensions manager and install this extension. right click and click "run python file in terminal" and you are all set.
this will run exactly as they run from the idle(which is default IDE provided by python itself) you can enter the arguments from the console itself. according to me this is the best way to run and debug python programs in VScode.
another way is that VScode shows which python version is installed on your computer on the left bottom side, click on it and the programs will use this interpreter.
out of all the ways listed here and many others, the best method is to run the program in the terminal which is the recommend by python itself and many other programmers.
this method is very simple. what you have to do is open up your command prompt and type the path where python.exe is installed and the type the path of the your program as the argument and press enter. you are done !
ex : C:\Python27\python.exe C:\Users\Username\Desktop\my_python_script.py
You can also pass your arguments of your program in the command prompt itself.
if you do not want to type all this and then just use the solution mentioned above.
hope that your query is solved.

how can I configure PyCharm so that running a Python script file is visible for Python Console

I am writing Python scripts in Pycharm with IPython installed. So I can use Python Console in Pycharm to type Python commands and check the immediate output of the codes. However, when I run a script file after pressing 'Run' button (Shift+F10), all the variables and functions are not visible to the Python Console. This is, however, the feature of Spyder, another popular Python IDE. So here is my question: how can I configure Pycharm so that running a Python script file is visible for Python Console? Thanks

You could also run the part of your code you want to test/check in the console by selecting it and then right clicking and clicking on "Execute Selection in Console Alt-Shift-E". That's what I use sometimes when the debugger is not helpful. After running the code (you can also just "run" functions or classes) the console knows the functions and you can use the same features that Spyder has. However, be aware that when you change the code you need to run it in the console once to update the console definitions!

You can not. But you can use pdb (which will break code execution where you need it and you will be able to do the same things, as in the Python Console).
And, which is better and more powerful, you can use PyCharm's debugger. It represents all available variables in tree-like structures and is really handy.

pycharm - keep focus in editor when sending commands to python console

Same question as
Sypder 2 IDE - keep the focus in the editor after sending selected commands to interpreter
but for JetBrains PyCharm. Using option-shift-e on a mac, I can send commands to the python console, but I have to press esc to return focus to the editor. Can I do the Rstudio-style / Emacs-ESS style execution where focus stays in the editor window?

I'm using PyCharm 2.7.3 on Ubuntu 12.04 LTS with Netbeans keymap.
I can use CTRL+ALT+E to execute selected command and for the first time the console has a focus, indeed (first time after lauching IDE). However, any further CTRL+ALT+E leaves the focus on editor. (I can switch back to the console, which is named Run, using ALT+4.)
If newer versions of PyCharm are behaving differently then maybe it's a bug.

Use the built in console and/or built in terminal.
