What exactly do you feel is wrong with that?
Is it the fact that the first slash after the colon is forward facing?
Or is there something else?

Could you please use a few more spaces. Both to indent the code (2 
spaces ids really the minimum and 3 or 4 is normal. But one is
useless) and to separate the functions vertically. (ie a blank line 
before the def statements)

It is really very hard work wading through this stuff! I don't know how 
you can read it but I'm struggling to see the structure.

I don't understand what that means?
