How to create array in python?

An array is basically a data structure which can hold more than one value at a time. It is a collection or ordered series of elements of the same type.

Arrays can only take a single datatype element.

Array in python can be created after importing the array module.

e.g.,

import array
arr=array.array('i', [1,2,3])
print(arr)

e.g.,

a=int(input("Number of elements in the array:-"))
n=list(map(int, input("elements of array:-").strip().split()))
print(n)

Here we can see in the above example that we have used the map function to take the input of the array from the user.

Basic operations on array:-

• Finding the length of array- Length of an array is the number of elements that are actually present in an array. We can use the function len() to achieve it.
• Adding an element in array- Functions used to add an element to an array are append(), insert() and extend().
• Removing an element- Functions used to remove or delete an element of an array are pop() and remove()
• Array concatenation- Array concatenation is done by using ‘+’ sign as we do in strings.

This is all about defining an array and basic operations on it.
