Robert,

>>> "0" * 7
> => "0000000"

Thanks, i am using this at the moment, just wanted to know if there is 
something faster - in Python zfill is faster than "0" * 7. I am just 
asking because i am using this a *lot* of times, so if there is an at 
least slightly faster alternative ,i should probably consider it. But if 
"0"*7 is the 'normal' way of doing this, it's OK with me.

Cheers,
Peter
