4. Pascal Triangle. Write a program pascal.py that builds and prints a two-dimensional list (a list of lists) a such that a[n][k contains the coefficient of the k-th term in the binomial expansion of (ty) These coefficients can be organized in a triangle, famously known as Pascals triangle. Every row in the triangle may be computed from the previous row by adding adjacent pairs of values together. Below is a sample invocation of the program s python pascal py 7 1 2 1 1 3 3 1 1:4 6 41 1 5:10 10 51 16 15 20 15 6 1 17 21 35 35 21 7 1 You program should contain the following finctions generate_pascal (n) wlich retunis a list of lists of the coelficients, ad print triangle(coeffs) which prints the corefficients one set per line
