Develop a class named Course that includes (1) instance attributes: courseid, coursetitle, credits (2) constructor takes arguments courseid0, coursetitle0, credits0 (3) __str__ method that produces text like CSCI120: Elements of Computing(4)

Sure, here's an example implementation of the Course class in Python:

class Course:
    def __init__(self, courseid0, coursetitle0, credits0):
        self.courseid = courseid0
        self.coursetitle = coursetitle0
        self.credits = credits0

    def __str__(self):
        return f"{self.courseid}: {self.coursetitle}"

In this implementation, the `Course` class has three instance attributes: `courseid`, `coursetitle`, and `credits`. The constructor takes arguments for each of these attributes, and assigns them to the corresponding instance variables. The `__str__` method is defined to produce a string representation of the course, in the format "courseid: coursetitle".

You can use this class to create instances of courses, like this:

course1 = Course("CSCI120", "Elements of Computing", 3)
print(course1) # Output: CSCI120: Elements of Computing
