I'd forgotten that one...

For the benefit of the OP, you need to import sys first
so it looks like:

>>> import sys
>>> sys.executable

You can also run:

sys.executable

from Python itself. For example, on my system:

py> sys.executable
'/usr/local/bin/python3.5'

It will probably be somewhere different on Mac OS.

Yes, the system Python is 2.7:

 Python 2.7.10 (default, Oct 23 2015, 19:19:21)
 [GCC 4.2.1 Compatible Apple LLVM 7.0.0 (clang-700.0.59.5)] on darwin
 Type "help", "copyright", "credits" or "license" for more information.

That's from El Capitan, a few OS releases behind.

 able to work with sublime text.


I think that's a text editor right?
Or is it more of an IDE? Can you run the code inside sublime?
Is that what you are trying to set up?


Subblime Text is just an editor. It's got lots of nice stuff but it isn't an 
IDE.



If that's the case you probably need to type in the path to the pyhon3
interpreter in Sublime's settings somewhere. Thats the same path you
got from 'which python3' above.


My Sublime text seems to be associated as the default app for opening .py files 
already. A little surprised here, I use vim mostly and thought I'd bound MacVim 
(the GUI form of vim on a Mac) for .py files.



If you need more details you will need to ask more specific questions.
Bear in mind that although some folks here use Macs most of us don't.


I live on a Mac, I'll watch this thread.

But yes, Alan's remark that Python isn't an "app" in the sense of a GUI tool is 
probably very pertinent.


Megan, you may be expecting Python to be a GUI app. It isn't, though it can be 
used to write them. You also need some sort of arrangement to edit python code 
and run it.


Such arrangements tend to come in 2 basic forms: an IDE (integrated development 
environment) which is usually a GUI app with both editing and running 
capabilities, or separate editor and run arrangements.


Sublime Text, which I gather you use, is, I thought, just an editor. You also 
need somewhere to run Python from. Those of use not using IDEs generally run 
the programmes from a terminal. Personally I use iterm3 for my terminals, lots 
of nice features.

Another pertinent question is what python did you actually install (i.e., where 
did you get it from)?  Different bundles install differently, so knowing 
exactly what you downloaded will help identify some of the other questions.

If you have downloaded v3.6 9the latest version) then it will say so at
the banner message that comes up when you run it.

AS to where it is located you can find that out at the Terminal OS
prompt by typing

$ which python3

However you should never need to modify it or do anything to it.

> I can’t find it anywhere in the applications

You probably won't see it in finder unless you navigate the file system.
It is not like a normal GUI style app.

[Tutor] unable to locate python on mac

[Megan Zirger]

Hi there, 

I am completely new to python and trying to learn how to set up and get going. 
The one problem is that I’ve supposedly downloaded the new version. When I run 
it in the terminal I see that I have the version but I can’t find it anywhere 
in the applications or anywhere on my computer as to make modifications and be 
able to work with sublime text. 

Your help is appreciated. 

Thank you, 

Megan
