Answer to Question #314810 in Python for xxx

Question

1.Convert the 1-D array to 3-D array

a = np.array([x for x in range(32)])

Answer:

print(o)

Output:

array([[[ 0, 1, 2, 3, 4, 5, 6, 7],

[ 8, 9, 10, 11, 12, 13, 14, 15]],

[[16, 17, 18, 19, 20, 21, 22, 23],

[24, 25, 26, 27, 28, 29, 30, 31]]])

2.Convert the value in the array to appropriate data type

a = np.array([[7.2, 5.4, 9.3],

[3.8, 6.7, 8.5]])

Answer:

print(o)

Output:

[[7 5 9]

[3 6 8]]

3.Extract value in between 7 to 15 from the given array

a = np.array([2, 6, 1, 9, 10, 3, 27])

Answer:

print(o)

Output:

[ 8 12 9 11]

Answer 1

1.

o = a.reshape(4,8)
print(o)

2.

o = a.astype('int32')
print(o)

3.

o = []
def extract_values(a):
    for element in a:
        if (element > 7) and (element < 15):
            o.append(element)
    return np.array(o)

extract_values(a)
