I am trying to help a buddy out. I am a C++ on Windows guy. This buddy

When learning any new language, I said, the first step would be a Hello
World program. Let's see if we can get that to work.
So my buddy creates opens the IDE they gave at the workplace, creates a
new project, adds a demo.py file, writes one line : print "Hello World",
hits Run in the IDE and indeed the display is shown at the bottom when
it executes.
I say the next step would be to get that to run on the command line. So
(keep in mind I know nothing about macs) my buddy opens a "zsh?" window,
cd to the directory, and I say the command i most likely: python demo.py
It looks like it executes but there is no output to the command line
window.
It should. In a Windows console, using 3.4:
C:\Programs\Python34>type tem.py # cat on Mac?
print('Hello World!')
C:\Programs\Python34>python tem.py
Hello World!

Without a copy of the file and command, as above, no.

Since you used 2.x print syntax: https://docs.python.org/2.7/
"Python Setup and Usage
how to use Python on different platforms"
"Tutorial
start here"

You might possibly enjoy Python as a complement to C++. Some people
prototype in Python and rewrite time critical functions in C++. One can
access .dlls either directly (via the ctypes module) and write a wrapper
file in C or C++. I believe Python has also been used to write tests
for C++ functions (I know this is true for Python and Java, via Jython).
Good docs. I got setup in Windows in 10 minutes.
