You shouldn't need a regexp for this. An easy way to count the trailing
zeros is:
- convert the number to a string;
- make a copy, stripping off the

It seems liking quitting, exiting, or stopping a program is a bit
controversial. I've tried using sys.exit(0) while debugging a program
in IDLE, but it asks if I really want to exit. I just want a no-fuss,
no-muss way of exiting the code in the same fashion that when I get

Thank you very much for this. It is very helpful. I will check my

try and convert the first value in the split list to a int (or float), if
that works then post the value.
if it throws an exception (ValueError) then catch that and pass, or do
whatever else needs doing with the listing.

It looks to me that your variable:
time = in_time.split(":")
is hiding the time module.

Further info. If I put
y = time.strptime("11 01 05", "%H %M %S")
both in the function and in the main body. Only the line above in the
function produces an error message.
Here's a simple program that creates the problem.

Thank you very much for the help and the math

Is there a way to connect to an HSQL database via Python? After some
googling, the only way I can find is to use jython and connect via jdbc.
I don't want to use jython, so I'm hoping there is another way.

The point of a lot of these challenges is to be smart with your math as well
as your code. A brute force approach isn't going to work very well,
especially in this case. An integer with 7^20 trailing zeros isn't even
going to fit in your RAM.
An observation: every trailing zero implies a fac
