NumPy provides us with various tools for creating an array. For example, to create a one-dimensional array of equidistant values with numbers from 0 to 10, we would use the arange() function, as follows:

>> NpArray1 = np.arange(10)
>> print(NpArray1)

The following result is returned:

[0 1 2 3 4 5 6 7 8 9]

To create a numeric array from 0 to 50, with a step of 5 (using a predetermined step between successive values), we will write the following code:

>> NpArray2 = np.arange(10, 100, 5)
>> print(NpArray2)

The following array is printed:

[10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85 90 95]

Also, to create a one-dimensional array of 50 numbers between two limit values and that are equidistant in this range, we will use the linspace() function:

>> NpArray3 = np.linspace(0, 10, 50)
>> print(NpArray3)

The following result is returned:

[ 0. 0.20408163 0.40816327 0.6122449 0.81632653 1.02040816
