In other words, your Python installation is working fine. So what's the 
problem?

python itself isn't normally in the path.  this is in common with every 
app you install on Windows, where they all go to their own place. some 
installers force-add their path to the environment, Python gives you a 
choice, which you can go back to the installer to activate. More 
commonly, if you use the python.org installer, you also install the 
Python Launcher which helps with a variety of problems, in particular 
with making sense  of when you have multiple Python versions installed. 
If you installed that, launch Python by typing "py" (rather than "python").
