The Complete UniPoly Class

This appendix contains the complete and final definition of the UniPoly class for univariate polynomials that we developed in Chapter 7, Organizing Objects into Classes.

"""The unipoly module contains the UniPoly class for polynomials.

class UniPoly:
    """Polynomial with one variable and integer coefficients.

    UniPoly creates a univariate polynomial with a single term
    and an integer coefficient. Polynomials may use different
    variables, here called 'indeterminates', but their names
    must each be a single alphabetic character. These polynomials
    are immutable.

    Parameters
    ----------
    coefficient : int, optional
        The coefficient of the term. Default value is 1.
    indeterminate : str, optional
        The "variable." Must be a single alphabetic...
