(In Python. Preferably with comments so I can better understand what you're doing. I am actually trying to learn this material, after all.)

Exercise 3.1: Plotting experimental data In the on-line resources you will find a file called sunspots.txt, which contains the observed number of sunspots on the Sun for each month since January 1749. The file contains two columns of numbers, the first being the month and the second being the sunspot number.

a) Write a program that reads in the data and makes a graph of sunspots as a function of time. b) Modify your program to display on the first 1000 data points on the graph. c) Modify your program further to calculate and plot the running average of the data, defined by

$$Y_k=\frac{1}{2r}\sum\limits_{m=-r}^r y_{k+m},$$ (formatting would not transfer over well.)

where r=5 in this case (and the y_k are the sunspot numbers). Have the program plot both the original data and the running average on the same graph, again over the range covered by the first 1000 data points.
