[O] passing entry property to a source code block?

[Piter]

Hi everybody.

I would like to get a property of org-mode entry and pass it as a string 
variable to a python source code.

Is it possible to do? I have been looking into attach screensshot code 
but since my elisp experience is very limited I can not figure  it out.

Any tips about it? may be I can use inline ellisp function in python 
source header?

Thanks.
