thanks! very clarifying. One more question though: after installing python3.5 I only have pip3 and pip3.5 from the command line. However, I issued the command 

python3.5 -m pip install matplotlib

and it all went like a charm. At the end of the install, it said "You are using pip version 8.1.1, however version 9.0.1 is available. You should consider upgrading via the 'pip install --upgrade pip' command"

However, the command 
pip install --upgrade pip' command
doesn't work. So, it seems like pip is not installed. which pip3.5 tells me

so I'm confused. I have only pip3.5 and the command python3.5 -m pip install .... automatically translates into pip3.5 ?
