Introduction to Replit
Replit is an online integrated development environment (IDE) or portal used for coding. It provides a graphical user interface for Python development. One of its key advantages is that you do not have to install anything before starting to code, thanks to the internet. Replit binds together various development tasks into a single view.
To start using Replit, you can open your browser and go to Replit.com. After seeing the main page, you click on “Start coding”. You may be asked for a username and password, but if you have a Gmail ID, you can typically click the ‘G’ icon to log in using your Gmail account.
Once logged in, you’ll see a screen or window. To create a new Python program, you go to the plus symbol and click on it. You then select Python as the language you want to code in. The system will provide a machine-given name for your project, often a random combination of words, which you can change. You then click on “create REPL”. A REPL (repository) gets created; it’s simply a place where you can come and code.
In Replit, you can type your code. For instance, you can type print hello. The features are often described as self-explanatory. To run the code you’ve typed, you come to the run button and click on it, and you will see the output in the console.
Replit organises various features which are accessible through icons on the left side panel. The first icon is for files, which allows you to see the files and folders in your project. You can add new files and folders using the options provided. Replit allows you to create multiple programs and organise them systematically using files and folders. Creating a file in Replit is also mentioned in the context of file handling.
Beyond basic coding and file management, Replit has many other features, including version control, packages, secrets, settings, databases, and unit tests. Within the settings, you can change the layout, for example, from the default side-by-side view to a stacked view, which places the coding area at the top and the console output below.
Replit also provides built-in help for commands like print, offering detailed information when you use the help feature. The sources note that integrated development environments (IDEs) like Replit automatically handle indentation.
While Replit offers many features for development, one source notes that it can sometimes take some time to display results. The goal is to provide you with enough features for starting with Python programming.

01 A Quick Introduction to Variables
In Python, a variable is essentially a name or a label that refers to a value or stored data. You can think of a variable as a basket in real life used to keep track of information in your program. Variables temporarily store data in the computer’s memory. Variables are created when they are first assigned a value. An assignment statement creates a new variable and gives it a value. For example, price = 10 creates a variable named price and assigns it the integer value 10. Similarly, x = 6 creates a variable x with the value 6.

1. Below is a list of numbers: 22, -17, 47, -2000, 0, 1, 43, 1729, 6174, -63, 100, 32, -9. How many natural numbers are there in the given list? a) 6 b) 7 c) 8 d) 9 Solution Based on the sources, the set of natural numbers is denoted by N. This set includes 0, 1, 2, 3, 4, 5, and so on. The sources explicitly state that whenever they are talking about natural numbers, it always includes a 0, even though some books may not. Natural numbers are primarily used for counting.

1. Which of the following option(s) is(are) true? Solution Based on the sources and our conversation history, we can determine which of the given inequalities between fractions are true by finding a common denominator and comparing the numerators. Rational numbers, which include fractions, can be written in the form p/q. To compare two fractions which have different denominators, there is no way to directly compare them. The only way is to convert them into equivalent fractions such that they have the same denominator. A number that is a multiple of both denominators can be used as the common denominator. Once the denominators are the same, you can add the numerators, or in this case, compare them.
