Hello everyone, welcome back to Programming In Python. Here in this post am going to tell you how to concatenate or merge lists. We can simply add any number of lists by just adding them like a normal add operation with `+`

operator.

#### Add, concatenate, or merge lists – Code Visualization

#### Task:

To merge/concatenate/add lists.

#### Approach:

- Read the input number asking for the length of the list using
`input()`

or`raw_input()`

. - Initialize an empty list
`lst = []`

. - Read each number using a
`for loop`

. - In the for loop append each number to the list.
- Repeat the above 4 points for the second list
`lst2[]`

as well. - Now add the two lists
`lst + lst2`

- Print the resultant list of the above operation.

#### Program:

__author__ = 'Avinash' lst = [] num = int(input('How many numbers in list 1: ')) for n in range(num): numbers = int(input('Enter number ')) lst.append(numbers) lst2 = [] num1 = int(input('How many numbers in list 2: ')) for n in range(num1): numbers = int(input('Enter number ')) lst2.append(numbers) merged_lst = lst + lst2 print("Merged List with elements from both lists:", merged_lst)

#### Output:

That is it for the post. It is that simple to add multiple lists into a single list, it is just like adding 2 numbers with a + operator, we add 2 lists with a + operator here, like `lst1 + lst2`
