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.

Running Python Scripts Outside of IDLE

1- i want someone to help with this part
https://automatetheboringstuff.com/appendixb/
about Running Python Scripts Outside of IDLE and sending command line args .
2- i converted my code to .exe by pyinstaller ; what's the difference between this and running it
as a script .
3-how scripts are done . i see experienced people says :"i made a script to do something for me " how is that done >?
*i'm a beginner so try to make answers simple as possible.

If you're wondering about command line arguments, look into the "argparse" library https://docs.python.org/3/library/argparse.html.
The difference in the .exe and the normal script is that that the .exe versions (conventionally) are able to be redistributed to other sytems that don't have python installed whilst still being able to run the script. If you're only making the script for yourself the only real benefit is that you dont have to enter your IDE (code editor) every time you want to run the code, however if it's still in development then you'd have to compile the code every time you made a modification if you're wanting to run the code as an executable, which is very impractical.
Your third part is very, very vague. Python can be very versatile and i recommend you continue looking at the automatetheboringstuff.com website if you're interested in making scripts that can complete repetitive activities (although i must strongly advise you against using scripts maliciously).

Issue with Python Batch file to run Python through Notepad++

EDIT: The code I wrote in my Python file was just this:
print "foo"
I'm using Windows XP Home Premium on this tiny little HP Mini 1000, and I want to run Python files, since we're learning it in school. I am aware of this topic, so I tried to run Python files using a batch file (python.bat), and I'm getting an error that says, "Can't find 'main' module in ''" whenever I run the batch file. I followed the instructions given here. All I did was change "Python26" to "Python33" because of the difference in versions.
Any idea what's wrong here? I really want to run Python files from Notepad++, so I don't want any alternative ways to run them.

This sounds like you don't have PYTHONPATH set up correctly. I suggest you review the documentation here:
http://docs.python.org/2/using/windows.html
Instead of calling Python, call cmd.exe and then use the set command to inspect which variables are set and how they are set. Run the exit command to leave the command shell. When you think you have the variables set up correctly, try again to run Python.
Good luck and have fun!

I use the command line interpreter or IDLE mostly (Win 8.1 now, but I've done so since Win XP SP2), but NPP is my main text editor, so I was curious about this issue.
When I was reproducing this, I was able to generate several errors, but the only one I got that was an exact match was when I failed to configure the Run option correctly.
You need to make sure to follow this step exactly in the instructions you were following. When you navigate to Run -> Run in Notepad++, you have to enter this exactly:
C:\Python33\python.bat "$(FULL_CURRENT_PATH)"
I am pretty sure you left out the "$(FULL_CURRENT_PATH)", or otherwise didn't add it correctly, as failing to do so causes exactly the same error on my end. Failing to include this means that when you run the batch script, you get the wrong input to the Python interpreter, causing the error.

Python curses Redirection is not supported

I am trying to use Curses in PyDev in Eclipse in Win7.
I have installed Python 3.2 (64bit) and curses-2.2.win-amd64-py3.2. When I input the following testing codes into PyDev:
import curses
myscreen = curses.initscr()
myscreen.border(0)
myscreen.addstr(12, 25, "Python curses in action!")
myscreen.refresh()
myscreen.getch()
curses.endwin()
It did not show any syntax error, so I think the curses was installed correctly.
However, when I ran it as Python Run, the output showed: Redirection is not supported. I do not know where this problem comes from. I googled a lot but can't find related information.

Recent PyCharm versions (I am currently running 2017.2, not sure when this option was added, or if it has been there the entire time) have the option "Emulate terminal in output console". Curses works with this option checked.

You cannot expect to use curses with a non-terminal.
Probably you get this because you are running the script from inside an IDE, like PyCharm or any other.
All IDEs do provide consoles that are not terminals, so that's where the problem comes from.

For a Pycharm user the solution given by codeape works fine :
Snapshot

You can't use any IDE to run python files with the curses package. I used to run in pycharm and naturally couldn't run.
Change to the command line to run:
for testing follow my following steps
on desktop open notepad and copy paste the code and save it as filename.py
open command line change directory to desktop use below command cd Desktop and hit enter type python example.py and hit enter, your program will definitely run

My workaround is to create a Run Configuration that calls a curses script. The little overhead is worth not having to switch to the terminal and manually run the script hundreds of times a session. I use Intellij but I imagine the process should be similar in PyCharm.
The desired result is the convenience of a button to run the script:
First create a script that calls the entry script, for instance:
ptyhon name-of-script.py
Then, to create a configuration for each script:
Go to Edit configuration.
Click the plus button and add a Shell Script.
Enter the path to a shell script.
Here is a picture of a directory with a couple of sample scripts.
I use this process to view my progress. My curses scripts are very modest so fortunately I can live without a debugger.

How to install python 3.2.3 on Windows 7 enterprise

although I have been using python a long time very easily in a Linux environment, I have tremendous trouble to even install it correctly in a windows environment. I hope this is a question to be asked here, as it is not directly a programming question.
Especially, I have the following problems:
When on the command line, python is not a recognized command. Do I have to set the Windows path manually myself? If so, how to do that?
When starting a python script, should this be done with python.exe or pythonw.exe? What is the difference?
I also tried to install ipython several times, it never got installed (even after following the starting ipythonenter link description here thread.
When starting a script with python.exe, a window pops up and closes immediately. I saw some hints in putting in a readline command, which is of no help if there is a syntax error in the script. So how to be able to keep the window open, or how to run the command on the cmd.exe?
Thank you for any help on these items.

1) Look here: www.computerhope.com/issues/ch000549.htm
2) It has already been answered, always try to use search before asking question:
pythonw.exe or python.exe?
4) When using cmd.exe just navigate to your script folder using dir for changing directories and C:,D:,etc. for changing drives. Then run script by typing just the script name. When installed correctly, Python automatically launches .py scripts with python, so you don't have to write 'python' before script name. When run in cmd, window will stay open. If you want it to stay open even when launching script with double-click, use function waiting for user input, see here How to keep a Python script output window open?

You might want to use Python3.3, there is a new launcher for Python scripts in it. By that, you can start Python scripts with py <scriptname> which has the benefit of being installed in your path (C:\Windows\system32) and you can use a shebang to tell whether the script is for Python2 or Python3.
Also
In addition to the launcher, the Windows installer now includes an
option to add the newly installed Python to the system PATH
(contributed by Brian Curtin in issue 3561).
