[amp_mcq option1=”arange” option2=”aspace” option3=”aline” option4=”all of the mentioned” correct=”option1″]
The correct answer is A. arange.
NumPy provides a function called arange which is analogous to range in Python. It returns an array of numbers, instead of a list. The syntax for arange is as follows:
numpy.arange(start, stop, step)
where:
startis the starting value of the sequence.stopis the ending value of the sequence.stepis the increment value of the sequence.
For example, the following code will create an array of numbers from 0 to 10, with a step size of 1:
“`
import numpy as np
np.arange(0, 10, 1)
array([ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9])
“`
The arange function can also be used to create sequences of numbers with a step size that is not a positive integer. For example, the following code will create an array of numbers from 0 to 10, with a step size of 0.5:
“`
np.arange(0, 10, 0.5)
array([ 0. , 0.5, 1. , 1.5, 2. , 2.5, 3. , 3.5, 4. , 4.5, 5. , 5.5, 6. , 6.5, 7. , 7.5, 8. , 8.5, 9. , 9.5])
“`
The arange function is a very versatile tool that can be used to create a variety of sequences of numbers. It is one of the most commonly used functions in NumPy.
The other options, aspace and aline, are not functions in NumPy.
