Python List Add/Append Programs

This article covers a wide range of methods for adding elements to a list, including:

• Basic addition techniques like append(), extend(), and insert().
• Appending multiple items, lists, tuples, dictionaries and objects.
• Performing list modifications such as adding at the beginning, middle or end.
• Advanced operations, including conditional appending, padding and merging lists efficiently.
• Performance considerations when using different list operations.

From simple cases like adding numbers to a list to more complex operations like padding lists, handling missing values, or appending to 2D lists, this guide provides insights into Python’s list manipulation capabilities.
