Array in Python:


An array is a data structure that stores data of the same type together in an organized manner. It is an ordered collection where we can access data through an index. Using arrays in Python is very easy, and it provides the facility to perform various types of operations such as Creation, Traverse, Search, Insert, Update, and Delete.

Creation of an Array:
In Python, we can create an array using the `array` module. Before using it, we need to import it. The syntax `array.array('i', [1, 2, 3])` creates an integer array.

Traversing an Array:
Traversing an array means accessing each element of the array one by one. In Python, this is easily done using a `for` loop.

Inserting an Element into an Array:
The `insert()` method is used to add a new element at any position in the array.

Searching for Elements in an Array:
We use the `index()` method to find a specific element in an array. It returns the index of the element if it is present.

Updating an Element in an Array:
To update an element at any position in an array, we can directly assign a new value through its index.

Deleting Elements from an Array:
In Python, we can delete an element from an array using `remove()` (by value) or `pop()` (by index).
