This is the url that I have https://math.berkeley.edu/~jcalder/126F15/hw1.pdf and I want to get only hw1.pdf of that url. 
And, I have used urlparse.urlparse(url).path in the library urlparse and it returned ~jcalder/126F15/hw1.pdf which is not what I wanted. 
Hence, can anyone show me how to do it please ?
