title: python tutorial - inserting a list into another list at a specific index
introduction:
in python, inserting one list into another at a specific index is a common operation that can be useful in various scenarios. this tutorial will guide you through the process of inserting a list into another list at a specified index using python.
code example:
let's start with a simple example to demonstrate how to insert a list into another list at a specific index.
explanation:
insert_list_at_index is a custom function that takes three parameters:
the function checks whether the specified index is within the valid range of the main list. if the index is out of range, it raises an indexerror.
the slicing operation main_list[index:index] is used to insert the sublist into the main_list at the specified index.
finally, an example is provided to illustrate how to use the function. in this example, sublist is inserted into main_list at index 2.
the result is printed to show the modified main_list after the insertion.
conclusion:
inserting a list into another list at a specific index in python is a straightforward operation. the key is to use list slicing to achieve the desired insertion. this tutorial provides a basic example and a reusable function that you can integrate into your python projects when needed.
