Hello @NinjaTurtles-cloud
I think is a typo, but here pip install web 3 you have a space between web and 3, so be sure you install it like this:
pip install web3
That warnings are related to env variables, they are not actual errors more like recommendations.
On VsCode on the bottom left corner make sure to select the correct python interpreter (the one you installed web3).

Finally some recommendations:

1. use virtualenv for your python projects.
2. use python version 3.8 (is the most stable for web3 dev).

I hope this info might help.

Hello @cromewar
Thanks for your answer.

Sorry i had written well
pip install web3 on VsCode
On the bottom left corner i see Python 3.9.6 and if i click on it i can switch the interpreter path like the screenshot.

I have to switch on python version 3.8 to follow the tutorial ?

I have to inquire to know how use a virtual env.
Do you think I can still continue the tutorial without installing a virtual env for now ?

virtualenv envs i just a way to have isolates instances of python in order to avoid dependency conflicts, but is not an obligation.
The version must be the same one as you have on the console, if you type python --version you'll find which version is the correct one.
