Online Course

We want to create a website for finding the best online courses. In order to store information about courses, we need a new OnlineCourse class. Could you implement it for us?

OnlineCourse __init__ method takes three arguments:

  • name - course name (should be stored in self.name)
  • description - course description (should be stored in self.description)
  • weeks - duration of the course in weeks (should be stored in self.weeks)
course = OnlineCourse(
    name="Python Basics",
    description="The best course to start learning Python",
    weeks=2,
)
print(course.description)  # The best course to start learn Python

Often we will receive information about the course in the form of a course_dict dictionary with such fields:

  • course_dict["name"] - course name
  • course_dict["description"] - course description
  • course_dict["days"] - duration of the course in days

To convert course duration to weeks, OnlineCourse should have days_to_weeks staticmethod, that takes one argument days and convert this number to weeks.

Note: The last week may not be whole.

Example:

OnlineCourse.days_to_weeks(10) == 2
OnlineCourse.days_to_weeks(14) == 2
OnlineCourse.days_to_weeks(15) == 3

OnlineCourse should have from_dict classmethod. It should take two parameters:

  • cls - a default parameter for classmethod
  • course_dict - a dictionary described above

Method should return a new instance of OnlineCourse with correct attributes. It should use days_to_weeks method to convert days to weeks. Example:

course_dict = {
    "name": "Python Core",
    "description": "After this course you will know everything about Python",
    "days": 12,
}
python_course = OnlineCourse.from_dict(course_dict)
print(python_course.weeks)  # 2
