Right you are. There is a pip.exe in the ./Scripts directory of Python 3.4.

I don't agree with the PATH set-up however; I try and avoid those and 
generally don't need them; my simple IDE knows where to look for 
binaries, and PATHs for different versions would clash. (The actual pip 
command was tried in the same place as python.exe, not from the root 
path as my example suggests. A search for pip.exe failed because that 
was 3.1.)

No, I asked for how to install numpy, and was told to install Anaconda. 
I didn't know it was so big. It's like asking where to buy a pint of 
milk, and inadvertently buying the whole store! Which does, after all, 
come with the milk I wanted...
