Error (Translated): The command "ffplay" is either misspelled or
could not be found.
I have the newest version of vsc installed and the path for the cmd is set to the original path "C:\WINDOWS\system32\cmd.exe". Both terminals have the same path.
Typing in 'python' works on both terminals, while plenty of other commands only work in the external cmd.
Why am i getting this error?
This problem also prevents me from using the module subprocess as every command is just 'not found'.
I noticed that your terminal window has a specific title, which means that you are not using the system default terminal. If you want to use the same environment variable in vscode, a common practice is to start vscode from that terminal, and the vscode that starts this way inherits its environment variable. Enter "code" in the terminal prompt and return to start vscode

I was trying learning about logging in python for the first time today. i discovered when i tried running my code from VS Code, i received this error message
/bin/sh: 1: python: not found however when i run the code directly from my terminal, i get the expected result. I need help to figure out the reason for the error message when i run the code directly from vscode
I've tried checking the internet for a suitable solution, no fix yet. i will appreciate your responses.
Python Interpreter to be set up. Many ways mentioned in the vs code documentation https://code.visualstudio.com/docs/python/environments, here easiest would be to open command palette and search for python interpreter and there you can enter the path of python/python3 installed.
You can use shortcuts "Ctrl+Shift+P" and type "Python: Select Interperter" to choose the python interpreter.
You can also click the button in the lower right.
The error message you are receiving indicates that the "python" executable is not found in the PATH environment variable of the terminal you are using from within Visual Studio Code.
Add the location of the Python executable to the PATH environment variable in your terminal.
Specify the full path to the Python executable in your Visual Studio Code terminal.
You can find the full path to the Python executable by running the command "which python" in your terminal.
Quick question regarding the installation of python. I've installed Python 3.7.7 using the Windows 64 bit installer. I also had the installer update the PATH variable for me.
But when doing a quick check with the command-line using the command: "python --version", I'm getting nothing.
Nothing. No error, just an endline.
User Path variable System Path variable command prompt
Edit(1):
By going to the directory with python.exe within the terminal using the command "cd C:\Users\Andrei\AppData\Local\Programs\Python\Python37\" and then using python --version. The command works. I'm receiving the python version 3.7.7 message.
In spite of the path variable pointing to the same folder though, the command still doesn't work when I'm outside it.
A very weird thing I realized is that the command "py" does have some output. Regardless of what directory I'm in.pyOutput
So that command works, while python --version doesn't. In spite of python --version working when I'm within the actual directory of python.exe.
I would assume that while I'm outside the python directory, there's some other executable that the system is accessing first? Regardless, I need all the functionality of python to work as I'm trying to get an external program to work with it and within that program, I'm getting the error that python is not installed. "Download python and add it to the path variable" it still says...
Edit(2)(SOLVED!):
There must've been some other folder within the path that had a python command that was overriding this one, as now it works and all I changed was the position of the folder within the path variable. It previously sat lowest, now it is the first one. And the command always works as intended, regardless of what directory I'm in.previous position new position
First, be sure you added the path to environment variable correctly
for testing, you can open your terminal in your path that you added to the environment variable and run python --version again.
If that not work for you try these solutions:
Close your terminal and open it again
or
try python3 --version instead of python --version
It's probably because you don't have Python installed through the Microsoft Store. You need to write "python" in the cmd and then a Microsoft Store window will pop up and let you download it.
I am running Windows 10. I have recently changed location to my python folder and interpreter.
Unfortunately, when i now run python scripts in command prompt, I always have to type "python" before the name of the script I want to run.
Running the script directly - for example: C:\Python 37\mypythonscript.py -generates absolutely no reaction from the command prompt. I simply get back directly to C:\Python37>
If I however run C:\Python 37\python mypythonscript.py, the script is properly executed.
I have changed all the file associations using "ftype" and "assoc" in the command prompt. When I start command prompt and type "python", the python compiler correctly starts.
My problem is that I always have to type "python" before the name of my script for the command prompt to recognize that it needs to execute python.
I would like to open command, change directory to the directory with my python scripts, and simply run the python scripts by running the name of the scripts (mypythonscript.py) without having to type "python" in front of it.
Could you please help me identify what is wrong? How can I once again run python scripts in the command prompt without having to type "python" in front of the script's name?
Thank you in advance.
If you use a python 3 Virtualenv in powershell the above problem can be very confusing. Typically "py .\yourscript.py" or "py .\yourscript" will work but ".\yourscript.py" or ".\yourscript" will fail and might return a "ModuleNotFoundError: No module named '<module>' " error.
This happens because your .py association is not correct as described by Eryk Sun in the above second remark. The "py launcher" he names is, in most cases, "C:\Windows\py.exe". I my case it was already installed and I just needed to adjust the .py extension as described by him. It can also be done via the "Choose default apps by file type" settings.
A useful help is to define "$env:PYLAUNCH_DEBUG=1" in your powershell. After that "py .\yourscript.py" will have extra output showing where your python executable is found.
If there is no extra output it means, as before, that you don't have ".py" associated with "py.exe". If you start a "cmd" and "ftype python.file" looks ok, you need to read Eryk Sun's first remark :-)
Just installed Anaconda3. It came with the Microsoft Visual Code editor. I would like to use the Anaconda Prompt instead of Powershell or the CMD window from within the editor. Is there a way to change the default?
I didn't find the exact answer I was looking for but I believe my solution may help others so I'm posting my workaround:
Conveniently the Windows CMD or Powershell terminal opens in the same directory as the folder loaded into the Visual Code editor so I wanted to maintain this functionality. Here is how I did it without changing any Environmental Variables.
First change the default terminal from within Visual Code to the CMD terminal instead of Powershell. Add the following code to a batch file.
call "c:\anaconda3\Scripts\activate"
Then I named the batch file and saved it to my root directory. In my case snake.bat. Now when I launch my CMD terminal I just type c:\snake.batand the CMD prompt changes into an Anaconda prompt.
The Visual Code Editor attempts to do this already, but has errors. I believe this is because it opens with Powershell instead of the CMD terminal by default.
I have installed the Enthought Python distribution on my computer, but I don't have any idea how to use it. I have PyLab and IDLE but I want to run .py files by typing the following command:
python fileName.py
I don't know where to write this command: IDLE, PyLab or Python.exe or Windows command prompt. When I do this in IDLE it says:
SyntaxError: invalid syntax
Please help me to figure this out.
Open a command prompt: Press ⊞ Win and R at the same time, then type in cmd and press ↵ Enter
Navigate to the folder where you have the ".py" file (use cd .. to go one folder back or cd folderName to enter folderName)
Then type in python filename.py
Indeed, the command to run a Python file should be run in the command prompt. Python should be in your path variable for it to work flexible.
When the python folder is added to path you can call python everywhere in the command prompt, otherwise just in your python install folder.
The following is from the python website:
Windows has a built-in dialog for changing environment variables
(following guide applies to XP classical view): Right-click the icon
for your machine (usually located on your Desktop and called “My
Computer”) and choose Properties there. Then, open the Advanced tab
and click the Environment Variables button.
In short, your path is:
My Computer ‣ Properties ‣ Advanced ‣ Environment Variables In this
dialog, you can add or modify User and System variables. To change
System variables, you need non-restricted access to your machine (i.e.
Administrator rights).
Another way of adding variables to your environment is using the set
command in a command prompt:
set PYTHONPATH=%PYTHONPATH%;C:\My_python_lib
If you do it via My Computer, then look for the line named path in Enviroment Variables. Give that the value of your Python installation folder.
Set PYTHON variable to point to the full path of python.exe.
Then type in command prompt console window:
C:\path_to_folder\ python filename.py
