[snippsat]

The basic.

# Make 
G:\div_code
λ python -m venv my_env

# Cd in
G:\div_code
λ cd my_env\

# Activate 
G:\div_code\my_env
λ G:\div_code\my_env\Scripts\activate.bat

# A test file
(my_env) G:\div_code\my_env
λ cat test.py
import sys

print(sys.executable)

# Start Vs Code
(my_env) G:\div_code\my_env
λ code .

So should have VS Code in Path so can use code .(to start VS Code from folder you are in).
Click on down in right corner over python version and it will bring up select interpreter as in image.

When run test.py,so will now use python.exe in my_env folder.

Output:
g:\div_code\my_env\Scripts\python.exe
