🖥️ Lists in Python: Definition, Syntax & Declaration

Python offers a range of compound Data Types, often referred to as sequences. Lists are one of the most frequently used Data Types. In fact, List in Python is a collection of items, which is: ordered, indexed, allows duplicate members, and is mutable – so it can be changed, once it has been created. Consequently, it is often use when you want to store an item, and then access it in a very particular order.

The important properties of Lists in Python are as follows:

○ Lists are ordered – Lists remember the order of items inserted.
○ Accessed by index – Items in a list can be accessed, using an index.
○ Lists can contain any sort of object – It can be numbers, strings, tuples – and even other (nested) lists.
○ Lists are dynamic – You can change a list in-place, add new items, and even delete or update existing items.

Great! Now that you have understood what a list is, let’s move forward and discover how to create a list in Python – but also what are all of the operations you can perform on it, in order to: add, remove, or access an item, or even search for a specific item inside of this list. So, be sure to stick around – and watch the entire video!
