Answer 1

Based on the output of your terminal, it seems the installation of Homebrew did not complete properly.

Indeed, as part of the installation, the Homebrew installer attempts to install the "Xcode Command Line Tools". For that, it asks you to press "RETURN" to confirm that you agree to install those, and then asks you for your password to obtain the permission to do it. That is, if you press RETURN and enter your password, the Homebrew installer should then be able to complete.

Once Homebrew is installed, you can use the brew command to install Python, similarly to your first attempt:

brew install python

Please note that brew install python installs Python 3. If at some point you want to install Python 2, use brew install python@2 .
