Array operations in Python

What is an array? An array is a collection of elements of the same type. Arrays are sequence types that behave very much like lists except that the type of objects stored in them is constrained. The idea is to store multiple items of the same type together.

How to access array elements in Python We can access each element of an array using the index of the element. Slicing Python arrays We can access a range of items in an array by using the slicing operator. Python also has what you could call its “inverse index positions“. Using this, you can read an array in reverse.

For example, if you use the index -1, you will be interacting with the last element in the array. Knowing this, you can easily access each element of an array by using its index number. For instance, if we wanted to access the number 16 in our array, all we need to do is use our variable (called with square brackets, []) and the index position of the element. The length of an array and how to change and add elements of an array Use the len() method to return the length of an array (the number of elements in an array.

Changing element Arrays are mutable – their elements can be changed in a similar way as lists. Insertion operation

Insert operation is used to insert one or more data elements into an array. Based on the requirement, a new element can be added at the beginning, end, or any given index of the built-in array.insert() function in Python.
