A cookiecutter template for competitive programming with mocked input and output to facilitate testing/TDD.
The advantage of this approach is that you can easily create methods to test inputs and outputs replacing values that are entered with stdin and stdout by entering the values in a string, and then just paste your solution on the contest directly.
The running time is also printed for each test by default.
Install cookiecutter:
pip install cookiecutter
Create a project using the template:
cookiecutter https://github.com/douglascdev/cookiecutter-competitive-programming
You'll be asked for the project name, which will be created at the current folder.
After that, you can implement the tests to make sure your code will work on the file cp_problem_tests.py, and your solution at cp_problem.py.
Further explanations are on the files.
