I insist, perhaps compeleld, to use a key to associate a number to a filename.
Would you help please?

I dont know this is supposed to be written. i just know i need this:

number = function_that_returns_a_number_out_of_a_string( absolute_path_of_a_html_file)

Would someone help me write that in python coding? We are talkign 1 line of code here....
