Please provide the code in Python.

1.Modify the bisection code in Sec. 3.1 as follows: a. At every step of the for loop, print the error. Recall that the "worst case scenario" error is given, at every step, by (a+b)/2. Store the error at the step i in an array element named err[i]. b. Add lines to plot the array versus its index. c. Notice that the graph you get is the graph of an exponential function. Replace the plot command with semilogy and see what happens. Explain why does it happen. d. Evaluate "by hand" the slope of the straight line you get in the previous point
