Python 3: Concept of LIST in Detail

The dictionary meaning of LIST is a number of connected items or names written or printed consecutively, typically one below the other.

In the real-world, lists are considered in many ways like a playlist of songs, a collection of your favorite videos, a list of user databases, and there are many more. But, if you are given a task about handling a list of users and filter out specific users under specific conditions then it becomes a tedious job to filter the list by going through each and every user. In such scenarios, programming comes into place to make your work easier.

So, now let us understand 'What is a LIST?' in python programming. In python, the list is a mutable or changeable, ordered sequence of elements where each element or value that is inside of a list is called an item.

In string, how each value/element is represented as a character, and similarly in the list, each value/element is separated by comma where each element can be a string, variable, or constants enclosed in the [] bracket.

Syntax of List: ['LetsUpgrade', 'Batch1', B2, B3]

Nested List: ['LetsUpgrade', ['java', 'python', 'c++'], 1, 2, ['B1', 'B2'], 'Exam']

Topics to be covered in the LIST are as follows:

Indexing Lists
Lists are Mutable
Updating and Slicing Lists
Use of operators in List
Methods used in List
Built-in functions in List
Deleting Elements from List
Constructing a List with List Items
List and Strings
Parsing lines
Objects and values
Aliasing
List arguments
List Comprehensions

🤔 Question:
You are Berlin, the second-in-command of the Royal Mint of Spain heist. You are well trained in various things along with your fellow robbers, and you learn all the details of the heist. You have taken over the Royal Mint of Spain and are ready to implement your plan for the heist. But before that, you need to transfer all the confidential data of the Royal Mint to the Professor. Write a script to automate the data transfer using Python or JavaScript.

Make sure the script is properly documented(using comments within the script).
