What happens when you activate a virtual environment named Foldenv in the terminal of python vscode and then use a virtual environment named venv in the palette?
i enter print ("hello world") in venv interpreter but terminal show me (Foldenv) in front of hello world
Python will use the python interpreter in the lower right corner (the one you selected in the Select Interpreter panel) to run the code.
But it doesn't activate another virtual environment again when there is already a terminal and activate a virtual environment. Unless you close the current terminal and run the code.
Another thing to note is that when you use the button to execute code in a terminal, then this terminal will always exist as the terminal for executing code. The following two cases are examples for your understanding.
The first case
Select the Foldenv environment interpreter and activate the environment in the terminal. Note that no code is running at this time.
Switch the interpreter to .venv in the Select Interpreter panel,
Use the play button to execute the code. At this time, a new terminal will be created automatically and the .venv environment will be activated to run the code.
The second case
Select the Foldenv environment interpreter and execute the code directly. A terminal is automatically created and the environment is activated at this point.
Switch the interpreter to .venv and run the code again. At this time, the code will be executed directly in the current terminal, but the .venv environment interpreter will be used.

As far as I know, for activating the virtual environment it's enought to just run pipenv shell
But in my case after running this command the parentheses at the beginning of the command prompt doesn't show up. Even after selecting the proper interpreter (the one inside venv folder)
To show the parentheses I should run activate command afterward.
So my question is: Is it important to show the project name in parentheses at the terminal prompt? Should I run the activate command after pipenv shell command every time?
I will appreciate if you describe the meaning of those parentheses. Tnx.
PS: I am using vscode in windows 10.
You do not need to activate the environment manually. When you select the python interpreter and open the terminal, vscode will activate it automatically for you.
The Python extension uses the selected environment for running Python code (using the Python: Run Python File in Terminal command), providing language services (auto-complete, syntax checking, linting, formatting, etc.) when you have a .py file open in the editor, and opening a terminal with the Terminal: Create New Terminal command. In the latter case, VS Code automatically activated the selected environment.
You can read document for more details.
How can I disable automatically activating the virtual environment?
Its shows my virtual environment
And i have to again install modules on the environment.
Pls help
You need to configure your python environment
Please click on the Python environment in the lower left corner of VSCode, and select the Pyhon environment you need, then use the shortcut key Cttrl+Shift+` to open a new VSCode terminal, it will automatically enter your currently selected Python environment:
If you are not using a terminal with activated virtual environment, it is recommended that you click the delete icon("Kill Terminal") to delete this terminal window.
I have django project folder with venv environment.
when opening vscode it has terminal opened in vscode.
Is there a way that I don't have to venv/bin/activate all the time when opening the project folder?
Edit (credit to #XJOJIX) from the comment in this answer. This will active the virtual environment without having to close or open terminals. A Python file still needs to be selected to load the Python extension.
Add this parameter in VS Code to "launch.json" or ".code-workspace"
"settings": {
"python.terminal.activateEnvInCurrentTerminal": true
}
Previous Answer:
To have a VS Code terminal automatically activate a virtual environment when first launching VS Code:
Close the terminal before exiting VS Code.
Open VS Code. Ensure a Python file is selected to direct VS Code to load the Python extension.
Wait for the Python extension to finishing loading (very bottom
left of VS Code terminal).
Open a new terminal after Python extension has loaded. The venv will automatically activate.
The trick is to open the terminal only after the Python extension has loaded.
If the directory of the terminal contains a virtual environment, VS Code will also automatically activate a virtual environment if a new terminal is opened. As before, a Python file must be selected and the Python extension must be fully loaded.
If you are on a mac OS, the simplest thing is to make ENV for your python projects.
Follow these simple Command in your Vs Code Terminal and you get your ENV activated :
Python3 -m venv env
source env/bin/activate
(The env in the first line is your env name so you can type any name)
Use the command palette to trigger the "Python: select interpreter" command. It should allow you to pick your virtual environment.

If you use window machine, it might locate at
env/Scripts/activate
You can run above in your vscode terminal to activate your venv
I want to open an existing virtual environment in Visual Studio Code. When I try to change the interpreter address inside of the settings.json (as instructed by https://code.visualstudio.com/docs/python/environments#_global-virtual-and-conda-environments) it doesn't work. With the virtual environment that I have, there is no python.exe file, I believe that is the issue as to why the following settings.json file doesn't work.
{
"python.pythonPath": "D:\\GitProjects\\OrganizationApp\\venv1\\bin\\python"
}
First of all Try open the root folder which venv folder resides in with Visual Studio Code.
(If you are on Linux you can just got the directory and open terminal and type code).
You should get a pop up to change the interpreter.
If not then Open your command palette Ctrl + Shift + P
Search for Python interpreter and select the Venv one.
According to your description, you could refer to the following steps to check the creation and use of the virtual environment in VSCode:
Prerequisites.
Check if python is available.
Enter cmd from the computer, enter the cmd window, enter python, and output the python version number to represent python is available.
If it is not available, please check the python installation package and check the python environment variables.
The python extension was successfully installed in VSCode.
Create and use a virtual environment:
Create a virtual environment in the vscode terminal. python3 -m venv ./venv1 or python -m venv ./venv1 Reference: virtual environments.
Select Yes when the prompt box pops up.
Then the interpreter will automatically be replaced with the created virtual environment.
After restarting VSCode, there is no python interpreter displayed in the lower left corner. We can create or open a python file and it will automatically display the interpreter.
Click on the interpreter to choose other available interpreters.
Use the shortcut key Ctrl+Shift+` to open a new terminal and enter the virtual environment.
Update:
When I open other projects or don’t open any project in VSCode , the virtual environment created before is not displayed in the python interpreter options. The reason is that the virtual environment we created is based on the current project and it exists in this project. like this:
Although this virtual environment is not displayed in other projects, I can use this virtual environment by selecting the python.exe of the virtual environment ( 'enter interpreter path' '.venv' 'Scripts'). Therefore, if there is no python.exe, it is recommended to create a new virtual environment.
I am just starting to set up virtual environments for my Python projects.
Up to now I have used and like Geany for development and testing.
When I set up my new virtual environment, what will I need to set in Geany to make sure it runs my Python code in the appropriate venv?
Thanks!
Start by creating a project file that resides in your venv folder. Then, point to the Python interpreter that resides in the venv folder using the build configuration feature. These actions will allow you to run the correct Python interpreter for each virtual environment you create and not affect the configuration of other virtual environments, other project configurations, or your base configuration.
To set Geany up so that it runs Python code in the appropriate venv, follow these steps:
1) Verify Geany is set up for Project Sessions. To do this, go to the main menu, select 'Edit', then 'Preferences'. The Preferences window will appear. Select the General Tab, then select 'Miscellaneous' tab. Now look at 'Projects' section on the tab. Verify both 'Use project-based session files' and 'Store project file inside the project-based directory' are selected.
2) Create a Geany project file in your venv folder. To do this, go to the main menu, select 'Project', then select 'New'. Give the project a name and save it in your virtual environment folder.
3) Configure the build commands for the above project. To do this, go to the main menu, select 'Build', then select 'Set Build Commands'. A window will appear. Look for the 'Execute' button on the bottom left of the window. In the command box next to the 'Execute' button type in the complete path to the bin folder in your venv folder that contains the Python interpreter you wish to run, then add "%f" to the end of the command. For example, my virtual folder is in home/my_virtual_env_folder and I want to run the Python3.4 intrepreter in that folder, so I would type in:
/home/virtual_env_folder/bin/python3.4 "%f"
Click 'OK' and the changes you made will be saved. Now when you open the project you just created, the project file will automatically point to the correct Python interpreter for the venv you are working in.
I am using Windows 10 and conda virtual environments, which I first have to activate before use. I was able to use these conda environments in Geany 1.36 by doing the following:
Go to menu: Edit - Preferences, in there go to Tools tab and in Terminal, type the following:
cmd.exe /Q/C conda activate envname && %c
Replace "envname" with the name of your conda virtual environment.
&& will also pass the argument %c to the execution line.
%c will pass the command in execute command from Geany (step 2).
Go to menu: Build - Set Build Commands, in there go to "Execute commands" section, and in Execute Command, type the following:
python "%f"
%f will pass the name of the file that you are executing from.
In the end it's like you are executing the following (assuming your python file is "script.py"):
cmd.exe /Q/C conda activate envname && python script.py
This worked for me. Just a note, when I installed miniconda, I added it to the PATH variables in Windows 10. That is why I don't have to add the path where the activate.bat or python.exe are located, they are already declared in the PATH variable from Windows.
This works for win10/11 python venv, in a cmd window, enter:
cmd /k path\to\venv\activate\activate.bat
in a .bat file to get a cmd widow then type geany.
Or a .bat file with:
path\to\activate.bat && Z: && cd Z:\path\to\project && python project.py
double click will launch your python file and destroy the cmd window on exit.
