A better way for "except" and "return"?

[Syver Enstad]

the first thing I see is that you could avoid the two try: except:'s
by moving both calls to curser.execute into one and deleting the rest.

Also I like better to return early on error, so to avoid the final
else you can negate the if expression at the top of the function and
put else code there.

My two cents :-)
