IN PYTHON!!!

(150pts) Design a Polynomial Class so that 1. The constructor can take an arbitrary number of coefficients starting from a0 to an. No-arg constructor will create an polynomial 0 (only a 0=0 ). 2. doc string of the class can be shown 3. Each Polynomial object p can be used to evaluate with different value of x : e.g. x=3 p= Polynomial (1,2,3) print(p(3))#34 4. Dimension: p.dim() \# In p's case, it should be 2 . 5. Addition and Subtraction of polynomials 6. Conversion of a polynomial to a string. (implement ___str__ and _ repr__ methods)
