Greetings,
Beautiful! Thank you SO much for all the variations.
I'm so sure I'll have much to learn from them. This
is exactly the kind of stuff I'm currently studying.
I have a question for the list.
After I posted my snippet, I added time to import,
and a time.sleep(1) line to the code. The reason
I did this is because I'm under the (possibly mistaken?)
impression that random uses the computer
time as a random number generator 'seed',
for generating pseudo-random numbers?
Perhaps this is a question for the 'language lawyers'?
Cheers!
