1. Open the Command Palette (Ctrl+Shift+P), then select the Python: Select Interpreter. From the list, select the virtual environment in your project folder that starts with .env.

2. Run Terminal: Create New Integrated Terminal (Ctrl+Shift+` or from the Command Palette), which creates a terminal and automatically activates the virtual environment by running its activation script.

3. Install sqlalchemy and mongoengine with command pip install. Once installing them successfully, there will intellisense when you import them and no warnings shown.

Besides, the folder .vscode is to store Workspace settings as well as debugging and task configurations.

Pylance requires you to set the Python PATH:

If you're in Mac/Linux, use:

which python3

And in Windows (Command Prompt cmd.exe):

where python

So that the path in which your Python is installed is returned.

Copy that path.

Go to your vscode and open the settings.json file (CTRL + SHIFT + P, and type "settings.json" at search bar)

Add the following key to the json file:

"python.defaultInterpreterPath": "<PATH RETURNED ABOVE>"

The path may look like "C:\\Users\\YOURUSERNAME\\anaconda3\\bin\\python.exe on Windows or "/usr/local/bin/python3" on Mac/Linux.

Note: backslashes in settings.json must be escaped with an additional backslash, so C:\Users becomes "C:\\Users".

The following documentation provides more information about how to configure Python for Visual Studio Code: https://code.visualstudio.com/docs/python/settings-reference

Pylance, by default, includes the root path of your workspace. If you want to include other subdirectories as import resolution paths, you can add them using the python.analysis.extraPaths setting for the workspace.

• In VS Code press <ctrl> + <,> to open Settings.
• Type in python.analysis.extraPaths
• Select "Add Item"
• Type in the path to your library /home/andylu/Dokumente/Allgemeines_material/Sonstiges/Programming/Python/Scripts/

Add the following configuration in setting.json to remove these warnings

    "python.analysis.diagnosticSeverityOverrides": {
        "reportMissingImports": "none",
        "reportUndefinedVariable": "none"
    },

Use ctrl + shift +p to open the command palette. Search Settings, there are two settings.json files here. User works globally, Workspace works only on the current workspace. If the same configuration exists in both files, Workspace will override the settings in User.

Please use the command "pip --version" in the VS Code terminal to check the source of the module installation tool "pip", the module is installed here:

Then use "pip show django-embed-video" to view that the module has been installed successfully:

Also, please try to reload VS Code after the module installation is complete.
