Write a python program that allows the user to navigate through the lines of text in a file. the program prompts the user for a filename and inputs the lines of text into a list. the program then enters a loop in which it prints the number of lines in the file and prompts the user for a line number. actual line numbers range from 1 to the number of lines in the file. if the input is 0, the program quits. otherwise, the program prints the line associated with that number.
it should be like as this sample run follows.
enter the input file name: quotes. xtxt
i cannot open the file quotes. xtxt - check the name and try again.
enter the input file name: quotes. txt
the file has 16 lines.

Function name: poly parameters: int returns: int description: a polynomial of degree n with coefficients a0,a1,a2,a3, . . ,an is the function p(x) = a0+a1x+a2x2+a3 ∗ x3+ . . +an ∗ xn this function can be evaluated at different values of x. for example, if: p(x) = 1+2x+ x2, then p(2) = 1+2 ∗ 2+22 = 9. if p(x) = 1+x2+x4, then p(2) = 21 and p(3) = 91. write a function poly() that takes as input a list of coefficients a0, a1, a2, a3, . . , an of a polynomial p(x) and a value x. the function will return poly(x), which is the value of the polynomial when evaluated at x.
