The error says it can't find the file hello.py. That means its probably in some other folder or you need to specify the full or relative path to the file This is a MacOS issue not Python, its how your MacOS shell is searching for the file.
If it is in the same folder try explicitly telling MacOS: $ python ./hello.py Or if it is somewhere else either cd to that folder or type the path: $ python /the/full/path/to/the/dfile/hello.py There are some environment variables you can set in your login script which will help MacOS find the files but they depend on which shell Terminal is running, tcsh or bash are the usual options. Finally there is a trick you can use on the hello.py file that means you can launch the .py file directly from Finder. It's called the shebang trick by Unix folks. Basically you add a line like #! /usr/env/python To the very top of the file. MacOS will then use that command to execute the script. If usr/env doesn't work type $ which python and copy the output instead of /usr/env Alan Gauld Author of the Learn To Program website http://www.alan-g.me.uk/ ----- Original Message ---- > From: Justin Bonnell <jwbonne...@gmail.com> > To: Alan Gauld <alan.ga...@btinternet.com> > Cc: tutor@python.org > Sent: Saturday, 26 February, 2011 6:49:37 > Subject: Re: [Tutor] Running Existing Python > > Okay.
