Homebrew changed a few formulae to meet their standards. "python3" was renamed to "python", and "python2" to "python@2". As for why, read this announcement: https://brew.sh/2018/01/19/homebrew-1.5.0 Since we install Python 3 via homebrew anyway, we now do the same for Python 2 as well. We do that because the system Python 2 of macOS comes without pip installed and this way seems cleaner than doing "sudo easy_install pip". The Python 2 formula is keg-only now, so it doesn't interfere with the system Python 2. Therefore we have to add its executables to $PATH ourselves.
