Create a 2-by-3 array containing the first six powers of 2 beginning with 20. Flatten the array first with method flatten, then with ravel. In each case, display the result then display the original array to show that it was unmodified.

Python

Question # 1:

(Filling arrays) Fill a 2-by-3 array with ones, a 3-by-3 array with zeros and a 2-by-5 array with 7s.

Question # 2:

(Broadcasting) Use arange to create a 2-by-2 array containing the numbers 0–3. Use broadcasting to perform each of the following operations on the original array:

1. a) Cube every element of the array.
2. b) Add 7 to every element of the array.
3. c) Multiply every element of the array by 2.

Question #3:

(Element-Wise array Multiplication) Create a 3-by-3 array containing the even integers from 2 through 18. Create a second 3-by-3 array containing the integers from 9 down to 1, then multiply the first array by the second.

Question #4: (array from List of Lists) Create a 2-by-5 array from an argument which is a list of the two five-element lists [2, 3, 5, 7, 11] and [13, 17, 19, 23, 29].

Question #5:

(Flattening arrays with flatten vs. ravel) Create a 2-by-3 array containing the first six powers of 2 beginning with 20. Flatten the array first with method flatten, then with ravel. In each case, display the result then display the original array to show that it was unmodified.
