Get the filename from a path

[12237ee1]

I have a large text file which has a lot of links and I need python script to extract all the names of the files which end with .pdf format and sorted without repeated result ?

Example:

http://www.123.com/file.pdf http://www.123.com/pdfhello
http://www.456.com/hello/one.file.pdf http://www.123.com
http://www.456.com/hello/one.file.pdf

I need the final result to look like this:

file.pdf
one.file.pdf
