Sounds like your OS file associations are all botched-up and the ".py"
extention has been linked (either by you purposefully, as a system default, or
as the side-effect of something else) to a texteditor program. It's easy enough
 to change this setting in the OS, and i believe there is a Python module or
two for the task -- if that's your cup-o-tea.

Granted, opening a text editor for unknown files is always a wise default
system setting as it avoids any exploits that may be initiated by a hapless
neophyte. Take, for example, the braindead Windozes default setting for
autorun, which has been the source of many nasty exploits. I suppose that Gates
 figures his user base is so dumb that they can't even find the My Computer
icon and double click it in order to access the contents of a removable drive,
CD-ROM, or whatever STD riddled device they happen to plug in. The wise windoze
 user knows that disabling autorun is paramount to ensuring a secure
experience, among other braindead defaults.

This is not really a "python" question, and is actually generally applicable to
 Operating Systems. And the solution is specific to each platform.
