Show us what you have so far

also, by "desk check table" do you mean "disc" check table?

What the hell is a desk check table, and what does it have to do with Towers of Hanoi?

def main(): n = input("please enter the number of rings on the starting tower: ") tower(n) def tower(n, a='A', b='B', c='C'): #move n discs from a to c using b as middle if n == 0: return tower(n-1, a, c, B)/> print a, '->', c tower(n-1, b, a, c) main()

that is my algorithm and an example of desk checking is http://www.scribd.co...king-Algorithms

MOD EDIT: Added code tags. When postings code...ESPECIALLY Python code...USE CODE TAGS!!!

Reason for edit:: gave code tag a tiny move

At the very top of function call, print all the variables. That seems to meet the criteria.

Note that in the algorithm you've given, no values actually change in the body of the function, so just one variable dump seems sufficient.

Ok forget the desk check i figure it out

I also changed the code what i need to do is convert it into pseudo-code if someone can help me with that.

def main(): # promt user to enter the number of rings on the starting tower # test input to see if its a number # if input is not a number prompt user for a number while True: try: n = input("please enter the number of rings on the starting tower: ") # assigns the input to tower function break except KeyboardInterrupt: break except: print "I said enter a number dummy!" tower(n) def tower(n, a='A', b='B', c='C'): #move n discs from a to c using b as middle if n == 0: return # swap values of a, b, c tower(n-1, a, c, B)/> print a, '->', c tower(n-1, b, a, c) main()

Can anyone help change that into pseudocode? or give me a heads up on what to do?

I think it goes something like this

f n is 0:

do nothing

else:

move n-1 disks from a to b using c as middle

move the last disk from a to c

move n-1 disks from b to c using a as middle
