Requirements

Python Scripts

• Allowed editors: vi, vim, emacs.
• All your files will be interpreted/compiled on Ubuntu 20.04 LTS using gcc, using python3 (version 3.8.5).
• All your files should end with a new line.
• The main.py files are used to test your functions, but you don’t have to push them to your repo.
• The first line of all your files should be exactly #!/usr/bin/python3.
• Your code should use the pycodestyle (version 2.8.*).
• All your files must be executable.
• All your test files should be inside a folder tests.
• All your test files should be text files (extension: .txt).
• All your tests should be executed by using this command: python3 -m doctest ./tests/*.
• The length of your files will be tested using wc.
• All your modules should have a documentation (python3 -c 'print(__import__("my_module").__doc__)').
• All your classes should have a documentation (python3 -c 'print(__import__("my_module").MyClass.__doc__)').
• All your functions (inside and outside a class) should have a documentation (python3 -c 'print(__import__("my_module").my_function.__doc__)' and python3 -c 'print(__import__("my_module").MyClass.my_function.__doc__)').
• A documentation is not a simple word, it’s a real sentence explaining what’s the purpose of the module, class or method (the length of it will be verified).
• You are not allowed to import any module unless stated otherwise.
