ParseMyCf-contest

A personal submission parser for CF, parsed by individual contests.

Inspiration Why work hard when Python is your pet ?

What it does

  • You are prompted the username
    • You are shown the no of contests the user has participated
    • You enter the no of recent contests you want to parse
  • The script starts scraping from the most recent contests
  • For every contest, A Folder is created having the format (name + username)
    • Each folder has all the submissions with their proper extensions.
    • Each problem has all its attempts(WA,AC,TLE,RE,ME) in serial order separated by appropriate delimiters
    • A contest-info .txt file is also created having all the miscellaneous information about the user's performance like - Rating Change, New rating, Rank, Problems successfully solved etc.
  • If a folder was previously present i.e a contest was previously parsed by this scraper, it'll ignore the contest and move one to the next unfinished contest

Some users may encounter a https error. Here's the walkthrough.

You need to change all the https to http and delete the argument verify = True from every get request. verify-true-git

The highlighted parts show the https and verify=True clauses. They need to be dealt with as described above the pic.
