In this topic I would like to show you have to use Visual Code to create project on Python 3.9, with environment variables, debug and unittest.

  1. The environment variables are good if you need transfer the python project maybe to other PC with different S.O

So lets do it.

  1. Create folder.
python3 -m venv .env

4. Check version of python and pip.

python3 --versionpip3 --version

5. Create simple file with one line

6 . On you terminar copy and see the result Hello World

Hello world

7. install next extension:

pip3 install “fastapi[all]”

8. on file paste

from fastapi import FastAPIapp = FastAPI()@app.get(“/”)
async def root():
return {“message”: “Hello World”}

9.Create a debug file from python-fast-api. Check in the root path that a new folder is created with one file inside it.

10. Run the debug and the result will be:

11. Configure the unit test. be sure that the icon is in VScode

12. Create folder and file.
