Thank you, the error have been caused due to the fact that the uploading 
procedure of my edited 'pelatologio.py' hadn't been completed yet, while 
i was requesting the execution of the script via browser.

I didn't had to do anything it solved by itself, after upload was 
successful and file got  unlocked for access.

Thanks Cameron, and indeed the error message as you printed the Unicode 
characters was saying in Greek that file was in use.
