Hi,
thanks for your advice,
all your words is correct.
first of all, i would like to say
that script source is not finished version,
just i was get it here and there, and just collect it.
im not familiar with python,currently im learning python.
but where is end of learning pyton? there is some end of learning python or
programming? 
i don't think so . also i know what i doing with my script at least.
and what is 'wtf' ? :)
