How to run updated python script in linux terminal

Question

I am missing something really obvious here... but when I run this program

python gregs_program.py

it will work fine.... but if I make changes and then save it, I go to run

python gregs_program.py

and it runs the old version (doesn't update my changes)! I notice I have both

"gregs_program.py" and "gregs_program.py~" when I do the 'ls' command in Terminal.

What am I missing here?

write permissions ? or maybe try copying it to another file and run it. files with ~ are temporary or backup files. — dnit13

The problem could only be a few things (all of which I have done before):

The editing window is not in the same place (directory/computer) as the run window.
There was an error writing the updated copy, maybe from a readonly filesystem, out of space, etc.
The editor is in some weird mode and did not receive a command to write.

@user3583384: we've all been there. To avoid keeping multiple copies of the source code, use a version control system such as git, hg (mercurial) for your experiments.
