How to import a file from one package into another in Python without using sys.path.append(…) in Visual Studio Code?

I am working on a Python project using Visual Studio Code (VSC) and have the following folder structure:

Python  
├──.vscode  
│   └── launch.json  
├── package1  
│   ├── __init__.py  
│   └── module1.py  
├── package2  
│   ├── __init__.py  
│   └── module2.py  
└── Python.code-workspace

I want to import module1.py from package1 into module2.py in package2. However, I’m facing difficulties getting the import statement to work correctly without using sys.path.append(…).

Here’s the import statement I’ve tried in module2.py:
from package1 import module1

However, when I run the code, I receive an ImportError stating that the module cannot be found. I have verified that both packages have an __init__.py file.

I have also tried modifying the launch.json file in VSC to set the PYTHONPATH and avoid using sys.path.append(…), but the import still fails. Here’s my current launch.json configuration:

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Python Launch",
      "type": "python",
      "request": "launch",
      "program": "${workspaceFolder}/package2/module2.py",
      "cwd": "${workspaceFolder}/package2",
      "env": {
        "PYTHONPATH": "${workspaceFolder}"
      }
    }
  ]
}

I would appreciate any guidance or suggestions on how to properly import a file from one package into another without relying on sys.path.append(…) and considering the project structure in Visual Studio Code.
