I am working on an extension right now, I want to get the svg file location / path of the file using python script. I tried using os.path() but I am getting the path of where I save the python but not where I save the svg file. 
 

PS: the python file and the svg is in different folder / directory

# Current svg save location (if has been saved)
document_path = self.document_path()
# Current SVG name in Inkscape
document_name = self.svg.name
# Current input file - a tempfile, current state of svg sent
# to extension system when extension was run.
input_file = self.options.input_file
