NumPy Activities: Activity 1: Create an array using arange, linspace, ones, zeros, eye, and diag. Use the functions len (), and NumPy.shape() on these arrays. Activity 2: Create an array using random numbers. Try setting the seed before creating an array with random values. Activity 3: Create an array a and use the function timeit to time a**2 and a+1. Activity 4: Create a simple two-dimensional array. How about odd numbers counting backward on the first row, and even numbers on the second? (Indexing and slicing) Activity 5: Create a multidimensional array and use functions like reshape and transposition. Compute statistics like std, mean and median across the different axis. Matplotlib Activities: Activity 1: Create a file in idlelib to generate a line and save it as test_matplotlib. With ref to file test_matplotlib. Plot the figures with a solid line dotted and -and save them as Fig 1, 2, and 3. Activity 2: Create a file with an image for a random array and save it as test_matplotlib_img1. With ref to file test_matplotlib_img1 plot and save the different figures as Fig 1,2 in two different colors.
