Download Codechef Long Contest

The long challenge problems are structured on basis of month and are numbered sequentially. The main aim of this small python script is to successfully download all the problem files in pdf format in our computer hard drive. There is a collection of all problems of a particular long Contest say JAN14 available in this link

Motivation

I was quite interested in competitive programming and wanted to solve as many problems of UVA to enhance my coding skills and become a better programmer. So a thought crossed my mind that why not download all the problems available in UVA in pdf format so that I would be able to at least think and read problems even in off-line mode. Then I thought why keep the script restricted for UVA only ? Then I extended the script to download all problems in a long contest from codechef. And further download all such long contests (12 such per year) so that I can practice even better. Recently I had learnt python and realised that it has various libraries for helping me achieve the same
