It's pretty unreadable. Variables and functions should have names that reflect what they are to represent. To quote Pep 8,

One of Guido’s key insights is that code is read much more often than it is written. The guidelines provided here are intended to improve the readability of code and make it consistent across the wide spectrum of Python code. As PEP 20 says, “Readability counts”.

So really can't help, have no idea what this is supposed to do. Make it readable and you will have more responses.
