spacing in python scripts #20
Description
I think it may be more conservative to uses "spaces" instead of "tabs" to indent lines in python code.
To wit, vi *pl seems to equate tab with 8 spaces, whereas vi *py sets tab to 4 spaces. Thus "tabs" appear definition-dependent and may cause problems when we edit the files with different editors.
No doubt this is all well known, and of course I know very little about python programming.
But it's worth following up, thus this "issue".
