How do I upgrade the Python installation in Windows 10

Question

I want to upgrade my python from  Python 2.7.11 to python 3.5. Should I  completely uninstall 2.7.11 and then install the new one?

Answer 1

If you have 2.x or 3.x version of python you can keep it and install the newer version of python. Or else you can uninstall it and then install the newer version using the installer. The new  Python 3 installations come with the py.exe launcher, which by default is installed into the system directory. This will help you skip the burden of putting put the current Python installation into PATH yourself.
