Assignment 5.1:
Create
a class whose constructor accepts 3 integers which are
the
coefficients a, b, and c of the quadratic equation ax^2 + bx + c = 0.
In
addition to "dunder" (magic) methods for init, repr, and
str,
implement methods to return
the discriminant and the 2 roots. Provide error handling for the case
where there are no real roots. Instantiate objects of the class that
test via assert statements that the correct values are returned in
the normal case, the case of 2 identical roots, and the case of no
real roots and that the errors are handled appropriately. Provide
that this class can
be imported for use in another
program. You do not have to provide that other program.
Assignment
5.2:
Define a base class and one
derived class wherein they both have magic methods for init and str;
they both have at least one attribute and at least one non-magic
method; and that the derived class has overrides for at least one
attribute and at least one non-magic method. Instantiate an object of
each class and test that the objects have correct values for the
attributes and return correct values when the methods are called. Use
assert statements for those tests. Provide that the class may be used
by another program. You do not have to provide that other program.
