Python programming

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:

a) Cube every element of the array.

b) Add 7 to every element of the array.

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.
