    Task 1: Basic Syntax and Flake8 Checker

    Python uses indentations to separate blocks instead of backets.
    Unlike most programming language (like C++), indentations in Python
    are required.

    See https://www.python-course.eu/python3_blocks.php for some examples.

    Flake8 (http://flake8.pycqa.org/en/latest/) could help you check these
    syntax error. It also regular your coding style. For example, using
    two whitespaces as indentation is allowed in Python. However, Flake8
    will tell you it is an error "E111: indentation is not a multiple of four".
    This is because when many people work on the same project, it would be
    confusing if people are using different identation style.

    Following the coding style in Flake8 is strongly suggested.

    will tell you it is an error "E111: indentation is not a multiple of four".
    This is because when many people work on the same project, it would be
