sure
In the uk there is a tv quiz show called countdown, maybe its on in other
countries too.
theres a game in that where your given six numbers and a target and you have
to get as
close to that target as you can using only the six numbers, you can add them
multiply them
subtract them etc. Im nearly sure its against the rules to divide a number
that doesnt go evenly
like 6/ 2 = 3 is okay but 6/4 = 1 is against the rules. So im trying to
write the game in python.

I knows it not a very important program and its not going to change the way
we use computers or
anything, but im writing it just for fun , to play it with my friends and to
have it as my first python project
to help me learn how to program. I was able to write the letters game easily
enough .Im finding the numbers
game more tricky :)
