line 1: import numpy as np

line 2: array = ______ ([1,2,3,4,5])

array

FILL IN THE BLANK

• np.Array

• np.array
• numpy.array
• np.arrayy

Line 1: array = np.array([1,2,3,4,5])

Line 2: print(array[2])

What will the code print?

• 3
• 6
• 4
• 2

import numpy as np

array = np.array([1,2,3,4,5])

array[1] = 7

print(array)

What does line 3 do?

• Prints the 'array' without any changes.
• Updates the value at index 1 in the 'array' to 7.
• Adds a new element with the value 7 at index 1 in the 'array'.
• Deletes the element at index 1 in the 'array'.

import numpy as np

array = np.array([1,2,3,4,5])

array[1] = 7

print(array)

What will the code print?

• [1,7,7,4,5]
• [1,7,3,7,5]
• [1,2,3,4,5]
• [1,7,3,4,5]

import numpy as np

array = np.array([1,2,3,4,5])

array += 10

print(array)

What does this code print?

• [21, 22, 23, 24, 25]
• [6, 7, 8, 9, 10]
• [11, 12, 13, 14, 15]
• [10, 10, 10, 10, 10]

import numpy as np

array = np.array([1,2,3,4,5])

sum_all = np.sum(array)

print(sum_all)

What is the result of this code?

• 10
• 15
• 20
• 25

import numpy as np

array = np.array([1,2,3,4,5])

sum_all = ______(array)

print(sum_all)

Fill in the blank

• np.Sum

• np.addition

• np.sum
• np.add

Line 1: array = np.array([1,2,3,4,5])

Line 2: print(array[___])

The code returns the following:

3

What should be in the blank?

• 6
• 4
• 1
• 2

import numpy as np

array = np.array([1,2,3,4,5])

array[__] = 7

print(array)

The code returns this:

[1,2,7,4,5]

What should be in the blank?

• 3
• 6
• 8
• 2

import numpy as np

array = np.array([20,30,40,50,60])

sum_all = np.sum,(array)

print(sum_allincluded)

What does the code print?

• 15
• 25
