In this tutorial, we'll learn how to insert a list in another list with different methods.

Method 1: Using extend()

The extend() is a method which adds the specified list elements on the end of the current list

Syntax

list.extend(iterable)

Example:

# list 1
list_1 = [1, 2, 3, 4, 5]

#list 2
list_2 = [6, 7, 8, 9, 10]

#insert list_2 into list_1 by usind extend() method
list_1.extend(list_2)

#print list 1
print(list_1)

output

[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]  

Method 2: Using List Concatenation

Syntax

list + list

Example

# list 1
list_1 = [1, 2, 3, 4, 5]

#list 2
list_2 = [6, 7, 8, 9, 10]

#insert list_2 into list_1 by usind  List Concatenation
list_1 = list_1 + list_2

#print list 1
print(list_1)

output

[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
