hi all:
I have a function to return (x,y) value, but sometimes it would naturally
unable to return those 2 values properly. I know what recursion is, and I
think all I got to do is to call this function a 2nd time and the problem
would go away.
How do I do recursion? The function basically look like this
def return_xy():
blah blah blah
return x,y
