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:
start
is the starting value of the sequence.stop
is the ending value of the sequence.step
is 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.
