Hi Pedro, I think I've seen some code that does this before, but I can't find it now. It's generally regarded as a crazy hack, and I wouldn't recommend anyone use it except as a joke/demo. Some of the reasons:
1. Downloading and running code from the internet if you mistype an import statement is a pretty major security hole. 2. Import names aren't always the same as install names (e.g. 'pip install pyzmq' -> 'import zmq'). There are ways around it (https://pypicontents.readthedocs.io/en/latest/ ), but it's not trivial. 3. Correctly installing a module and then loading it in your running process isn't always easy: what if it requires an updated version of another package you've already imported? 4. Having a separate step where you explicitly install things makes it easier to customise the process of finding and installing them, e.g. if you want to run software on a machine which doesn't have an internet connection. It might be convenient for some use cases to have 'magic' imports that install the package if necessary, but overall it would be unreliable and confusing. There are various efforts to simplify managing dependencies of a project - see e.g. https://pypi.org/project/pipenv/ or https://pypi.org/project/poetry/ .
