Answer 1

Explanation:

so much big one not clear which class this much ask ur teacher

Answer 2

Answer:

(a)

import numpy as np

zeros = np.zeros((10,))

print (zeros)

(b)

vowels = np.array(list('aeiou'))

print (vowels)

(c)

ones =np.ones ((2,5),dtype=int)

print(ones )

(d)

myarray1 =np.array([[2.7, -2, -19],[0, 3.4, 99.9],[10.6, 0, 13]])

print (myarray1)
