book1-D Arrays

A one-dimensional array is a collection of elements, all of the same type, indexed by sequences of natural numbers.

Let's have a look at an example of creating a 1-D array:


              
1234567

            
import numpy as np

# Creating array
arr = np.array([1, 2, 0, 0])

# Displaying array
print(arr)
copy

Note

We should use the np.array() function and enclose your 1-dimensional array in square brackets. For example: np.array([value1, value2, value3]).

Select all options with the INCORRECT code for creating a 1-D array.
