List Modification and Addition with Slice Lists | Python Programming

📝 Slice lists are used to access specific values in a list.

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

➕ Using slice lists, you can modify and add elements to 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.

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

➕ 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.

📝 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.

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

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

💡 The 'Insert' function requires specifying the index position and the value to be added.

💡 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.
