Question

Using the arrays created in Question 4 above, write NumPy commands for the following:

1. Find the transpose of ones and myarray2.
2. Sort the array vowels in reverse.
3. Sort the array myarray1 such that it brings the lowest value of the column in the first row and so on.

Answer 1

a) 

ones_transpose = ones.transpose()
myarray2_transpose = myarray2.transpose()
print("Transpose of ones:\n", ones_transpose)
print("Transpose of myarray2:\n", myarray2_transpose)

Output:

Traspose of ones:

[[1	1]
[1	1]
[1	1]
[1	1]
[1	1]]

Transpose of myarray2

[[4.	24.	44.]
[8.	28.	48.]
[12.	32.	52.]
[16	36.	56.]
[20.	40.	60.]]

b) 

vowels_reverse_sorted = np.sort(vowels)[::-1]
print("Reverse sorted vowels array:\n", vowels_reverse_sorted)

Output:

Reverse sorted vowels array:
['u' 'o' 'i' 'e' 'a']

c) 

myarray1_sorted = np.sort(myarray1, axis=0)
print("Sorted myarray1:\n", myarray1_sorted)

Output:

[[0.	-2	-19]
[2.7	0.	13.]
[10.6	3.4	99.9]]
