Codeforces Parser Python v1.5.1

Summary

Codeforces is a website for competitive programming. It holds contests, so-called Codeforces Rounds, about every week.

This is a python program that parses the sample tests from the contest problem pages. For each problem, it generates the sample input/output files and a shell script to run sample tests.

This project is adapted from the C++ Codeforces Parser you can find in this article: http://codeforces.com/blog/entry/10416, the major difference being right now that Python scripts are generated, instead of C++.

Example:

./parse.py contest_number (e.g. ./parse.py 513)

Where 512 is the contest number, not the round number! Check the URL of the contest on your browser, that is the number you are supposed to use.

Effect:

What will happen, for example, if ./parse.py 512 is executed?

1. Directories 512/A, 512/B, 512/C, 512/D and so on are created depending on the contest number of problems.
2. For each problem, main.py is copied and renamed to the problem letter to the corresponding directory. You can put the path of your usual template in parse.py:20.
3. Problem page is downloaded from Codeforces website, and parsed. Sample input/output files are generated, e.g. input1, output1, input2, output2 and so on. You can create your own test cases after that, just keep the same naming format as others test cases.
4. A script test.sh is generated. You can use it to compile and run the sample tests after you finish coding. Just run ./test.sh in the problem directory.

What will happen if ./test.sh is executed?

1. Run each sample tests on your Python program, and check the output by diff. If it's correct, print Accepted, or else print the sample test that went wrong.
2. Please note that for problems with multiple correct answers it might say that your output is incorrect.
