Revision Chapter 1 - Algorithm and programming(9adv)

Ali has created a small program in Python, but he wants to store his data in a multi-dimensional array. He would like to use advanced mathematical and scientific calculations in his program. Ali should add the ___________ library to his program.

• Sum

• NumPy

In NumPy, the ________ function is used to change the rows to columns, and the columns to rows.

• array

• transpose

In Python, the data structure that stores elements of the same data type is called an array.

• True

• False

Meera has created a small program in Python. She wants to store elements of the same data type in an organized data structure using the NumPy library. To do this Meera should use the NumPy __________ function.

• array

• transpose

The line of code to the right will import the NumPy library. The "np" is an assigned name for the library. ( import numpy as np )

• true

• False

What would be the printed output of the Python code to the right?

import numpy as np

x= np.array(['hamad',60,80])

print ( x)

• np_Hamad

• ['Hamad' '16' '60']

• ['Hamad']

The line of the code to the right, will create an array that carries values from 0 to 10 with step size 2.

array= np.arange(0,20,2)

• True

• False

In the NumPy function, the data preparation technique that is used to help machine learning algorithms is called _________.

• reprint

• reshaping

In NumPy, to append two arrays vertically the function __________ is used.

• vstack()

• sum()

The line of the code to the right, will create a NumPy array from a list.

numpy.array([list])

• True

• False
