Let’s do zero because that is where we want to put it right at the very beginning and then the value that we intend to insert which is 1.8 and then going to print out the whole of the array again. And now we need to choose the location that we’re going to insert into our array just by using the indexing that we have just covered above. So to insert a new value into our array, we simply need to do our array name, which is abc and then dot insert, open up brackets. We may also slice with minus numbers, so will be the end number. This lets us print the first item which should be 2.5 and then the 3rd one which is 11.5. Now it’s worth noting we can actually index arrays as well. We can simply do that by saying for i in abc print(i). Using a for loop we can go through all the values in an array and print them all then display them on a screen. Now we can just print the whole thing out, and we expect to get an array as the output as shown below. We have just created an array containing floating-point numbers. So let’s just do 2.5 and then a comma 3.6, another/comma 5.6 And then let’s do 11.5 So because these are all floats, we are going to be using decimal point numbers. The next thing we need is the comma and now we can use the square brackets to actually input the values that we want into this array. Which represents a double float type of data. There are several types of code each representing different data types that can be contained in an array, in this case, we are going to use “d”. However, the first letter or the first thing that we place inside the parentheses denotes the data type that is going to go into this specific array. We are now going to type the word array, the next thing that comes is quite important. The next thing we need to do is we need to access the class that we imported as “arr”. So in this article, we are just going to name it ‘abc’ for lack of a better word. The next thing that we need to do is define a name for our array. This lets us have access to class data objects from the python standard library. Note that we have used “arr” as an alias since it is easier to type. This can be done using the statement “import array as arr”. Python arrays do not have inbuilt support in python, therefore we need to import the array module into our workspace in order to use Python arrays. For example, they all have to be integers or numbers or strings of characters. A Python array is a data structure in python that can hold multiple elements of the same type at the same time.
