NumPy in a Nutshell

## 1-D Arrays

How about more complex arrays? What is a one-dimensional array?

**One-dimensional array** is a table of elements, **all of the same type**, indexed by sequences of natural numbers. Let's take a look at the example of creating a 1-D array:

Note the syntax for creating a 1-dimensional array. Unlike a 0-dimensional array, here we need to call the

`np.array()`

function and enclose your 1-dimensional array in parentheses, which is enclosed in square brackets. Like this example:`np.array([value1, value2, value3])`

.

Select all options with the INCORRECT code of creating 1-d array.
