Write a program in Python that evaluates polynomials at given points. In other words, given the number x and a list of of coefficients ordered from highest to lowest: a_n, a_n?1, ... , a₂, a₁, a₀, your program should return the value of the polynomial evaluated at x, i.e. a_nxⁿ + a_n?1x^n?1 + ... + a₂x² + a₁x + a₀.

Hint: Power operator in Python is **, as compared to ^ in Matlab.
