Visual Code how can I activate the virtual environment automatically?

Maybe a simple question, but I cannot figure it out. I work within Visual Studio Code on a MacBook. Within a directory I create a virtual environment and have activated that with source .venv/bin/activate scripts and everything works fine.
In the terminal I see (.venv) (base) gaston#MacBook-Pro WebScraping %
When I start visual code another time and open this same directory I do not see the (.venv) so I again give manually the command to activate.
My question is there a way to activate the virtual environment automatically when opening the directory?

VS Code Default Python Interpreter Path
You can do this in a number of ways. If your goal is to have the virtual environment selected immediately at the launch of VS Code, you will have to target that virtual environment as the Python Interpreter in VSC.
https://code.visualstudio.com/docs/python/environments
System Preferences->Settings->Python: Default Interpreter Path
You'll want to point it to your virtualenv Python installation, likely something like:
envFolder/bin/python3
VS Code Launch Configuration Python Interpreter
You can also set a specific launch configuration so that VSCode will still use your system Python instance by default; however, specific launch configurations will have the virtual environment specified.

I did something within settings and now it works.
When I open VSC now it opens the directory and the right environment, just the way I wanted it.
Took me some while to figure what finally did the trick:
I opened settings Command + , typed env in the search box. Scrolled through the results until I saw:
Python > Terminal: Activate Env In Current Terminal
and checked the checkbox. That solved my problem.

I can't run python on visual studio code

Image case for the problem
I was following the Visual Studio Code tutorial for python here
https://code.visualstudio.com/docs/python/python-tutorial
I downloaded Python, installed the python extension in Visual Studio Code and set the python interpreter to python3.8 . I also checked the workspace settings to see if it had given the correct path. Then, I wrote a simple hello world program but this is the error it is giving me.
This is the python path it has in the settings.
C:\Users\Dell\AppData\Local\Microsoft\WindowsApps\python.exe
Program:
print("Hello World")
Error:
C:/Users/Dell/AppData/Local/Microsoft/WindowsApps/python.exe c:/Users/Dell/hello/hello.py
-bash: C:/Users/Dell/AppData/Local/Microsoft/WindowsApps/python.exe: No such file or directory
I tried uninstalling and installing all the extensions again but it didn't work. I also uninstalled and installed all python related things on my computer. That didn't work either. What should I do?

reinstall python and this time, add python to the PATH (there is an option on the installation screen. Check it as it isn't checked by default). Then try running vs

Your environment path is not configured properly reinstalling python will fix this make sure you install python from actual application and not from vscode.other solution is that you can set the enviornment path manually just go to the environment variables> under user variable set the path to your python.exe the above mentioned location seems unlikely it should contain main python folder such as Python37/....

I will suggest you follow the link mentioned in this blog post to have python installed and working with Visual Studio Code. https://techdirectarchive.com/2023/01/17/getting-started-with-python-automation-in-windows-with-visual-studio-code/
Microsoft recommends installing python from the Microsoft Store. since installing from the Microsoft Store uses the basic Python3 interpreter, and handles the set-up of your PATH settings for the current user (avoiding the need for admin access), in addition to providing automatic updates.

VS Code doesn't recognize Python Virtual Environment Packages - It shows red underlines

I installed python virtual env. I use vs code. I imported scrapy in my code and vs code doesn't recognize the module. Actually, it works well when I run it. scrapy crawl tester
Just, vs code shows red underlines that mean "Unable to import scrapy" So this is just vs code issue, not venv or scrapy package install issue.
This code works well and actuallay, scrapy is imported without any issue. This is just vs code issue. Thank you.

You might be able to solve your problem by using CTRL+Shift+P to add "Python: Select Interpreter" to your project.

If you created a virtual environment and activated it as well
type which python on macOS/Linux,
type where python on Windows,
inside the activated terminal session.
(env) userpc#pc:~$ which python
/home/userpc/Desktop/foldername/env/bin/python
In VSCode press Ctrl+Shift+P, under >Select Interpreter paste the location you receive using the former command.
Once done, restart VSCode.
VSCode will also ask you to install pylint in your environment and if it doesn't you can do the same by activating you environment and typing
pip install pylint
inside the activated terminal session.

Ran into the same problem - selected the correct Python interpreter in VS Code, pip installed all the desired Python libraries but import is still underlined in VS Code.
What you need to do
What worked for me is to make sure that the linter that you are using in this VS Code instance (I was using pylint) is from the bin folder of the virtual environment, not somewhere else.
How you can do it
I'll use the absolute path to the desired virtual environment /User/ProjectFolder/env as an example.
To check that you meet the conditions stated in What you need to do, toggle the settings.json file in VS Code by pressing ⌘ + ,:
Make sure that the correct Python interpreter is selected. i.e. "python.pythonPath":/User/ProjectFolder/env/bin/python3.
Make sure that the linter (e.g. pylint) is located in that bin folder, not anywhere else. i.e "python.linting.pylintPath":/User/ProjectFolder/env/bin/pylint, NOT something like "python.linting.pylintPath":/usr/local/bin/pylint.
This means that you have to install your desired linter in the virtual environment.
Hope this helps.

I tried #cleon-w's answer which worked for me. (Thanks Cleon)
I was using pyenv on my Mac M1 (Big Sur) with vscode. vscode could not resolve the
paths to python that the pyenv provides, so I looked within the pyenv scripts to find the absolute paths
to the underlying python and the pylint files.
As #Cleon W says I ensured pylint and python are in the same bin directory.
Then edit VS Code settings.json to point to them directly (bypass .pyenv) and the imports could be found.
settings.json (vscode)
"python.defaultInterpreterPath": "/Users/USERNAME/.pyenv/shims/python",
"python.pythonPath": "/Users/USERNAME/.pyenv/versions/3.9.1/bin/python",

I have similar problem with Django. What solved my problem was:
create .vscode/settings.json file inside root dir for project.
add this json {"python.defaultInterpreterPath": "path to bin directory in root dir for project"}
Ctrl-Shif-P -> Python: Select Interpreter -> select one that said: Use Python from python.defaultInterpreterPath. If it's not in the list, hit refresh (circled refresh button on the top of settings box).

How to use virtual environnement with VS Code?

I used Sublime Text so far for my Django / Python developments but I want a more complete IDE including debug and console built and my choice was focused on VS COde
the problem is that I have a little trouble to start, or more exactly to launch a project
I developed a project in a virtual environment venv
I can not activate this virtual environment from VS Code Console
I read the VS Code doc about it and you have to select a Python interpreter Ctrl + Shift + P but I do not see my virtual environment
can someone explain to me and help me?
thanks in advance

This depends on what implementation of virtual environments you are using.
If you are using the standard venv or an implementation that's similar to it, such as virtualenv, just create the environment in a subfolder of your project, like this:
It will be auto-detected in this case. If you are using something like virtualenvwrapper or pipenv, the environments should be auto-detected as well.
However, if VSCode is failing to find your environment automatically, you may set the path to it manually. Inside your project root, create .vscode/settings.json with the following in it:
{"python.pythonPath": "path/to/python.exe"}

Prevent Visual Studio Code from activating the Python virtual environment

With a Python project opened, whenever I open the integrated terminal in Visual Studio Code it's automatically activating the virtual environment. I'm sure that's done by VS Code because I can find this command in the bash history of that terminal:
source <project-directory>/venv/bin/activate
I don't want the virtual environment to be activated. How can we prevent VS Code from doing that?

Add "python.terminal.activateEnvironment": false to your settings (globally to your user settings if you never want it, otherwise your settings.json file which is found in .vscode directory; this folder is found in your workspace directory if this is a per-workspace thing for you; docs).

If you open the vscode terminal first and then select python interpreter, then it won't activate the python environment. This answer works in vscode 1.44.0 with pyhton 3.8.1. I haven't tested with other versions. However, if you have any files or workspace open you need to close that first to close the python interpreter. You don't need to make any changes in settings.
