Light tool to extract CodeForces problems into PDF files
I was training in someday and I was tired from sitting in front of the laptop, so I decided to download CodeForces problems in PDF, then print them and solve the problems on my bed!
Unfortunately, there was not any good way to download CodeForces problems in PDF, I was looking for a PDF file that contains one problem with its statement only, without CodeForces` logo, tags or anything else.
So I've written this code in Python. However, this is my first Python code and I've extracted all CodeForces problems in PDFs, you can find them here (there are crazy facts about CodeForces in that repository).
Ok, to be honest, training was not the only thing motivated me to do this, I was looking for some small project to try Selenium on it, so this was the key of motivation.
Have fun with your training.

- The code in this repository tested on Ubuntu 18.04 LTS
After downloading the files in this repository (codeforces2pdf.py - css.css), from terminal you can run them as follows:
-
Extract the entire contest problems in one PDF file:
~ python3 codeforces2pdf.py <contest_id> -
Extract one problem from a contest:
~ python3 codeforces2pdf.py <contest_id> <problem_character> -
Extract a range of problems from a contest to one PDF file -set the end to Z for open ended range-:
~ python3 codeforces2pdf.py <contest_id> <start_problem_character> <end_problem_character>
