List Modification and Addition with Slice Lists | Python Programming

Learn how to modify and add elements in a list using slice lists. Discover different types of list slicing and three methods to add elements in Python.

00:00:00 In this video, Cahyo discusses how to modify and add elements in a list using slice lists. Slice lists allow access to specific values in a list, and multiple values can be accessed at once.

πŸ“ Slice lists are used to access specific values in a list.

πŸ”€ In slice lists, you can access multiple values by specifying a range of indices.

βž• Using slice lists, you can modify and add elements to a list.

00:01:05 Learn about different types of list slicing, including taking elements from a certain index to the end and replacing values within a list.

Slice lists can be used to extract a range of elements from a list.

Another use case of Slice lists is to extract all elements from a list.

Values in a list can be replaced using indexes.

00:02:09 The video demonstrates how to change specific values in a list and add elements to the list using different functions.

πŸ”’ You can change the values of specific elements in a list by using square brackets and indices.

βž• There are several functions available to add elements to a list, including append, extend, and insert.

❌ Append adds elements to the end of the list, extend combines two lists, and insert places a new element at a specified index.

00:03:11 The video explains three methods to add elements to a list in Python: append, extend, and insert.

πŸ“ The video explains three different methods for adding elements to a list in Python.

🧩 The first method is to use the 'append' function to add elements at the end of the list.

πŸ”— The second method is to use the 'extend' function to add elements from another list to the end of the original list.

00:04:17 Learn how to insert a value at a specific position in a list. Example: Given [10, 14, 18], insert 3 at index 1, resulting in [10, 3, 14, 18].

πŸ’‘ Inserting a value at the first index or second position in a list causes the existing values to shift right by one position.

πŸ’‘ The 'Insert' function requires specifying the index position and the value to be added.

πŸ’‘ In the given example, the list initially contains the values 10, 14, and 18. After inserting the value 3 at the first index, the resulting list becomes 10, 3, 14, and 18.
