    What you are asking for is the course that your instructor should
    be teaching.

    If you want help here, make an attempt (i.e. read the material
    mentioned in the assignment, break the task into its component
    parts, code each part) and post your code here when you have
    problems.

    For example, learn how to do this before tackling other parts of
    the script:
