Basic syntax and concepts
Variables
A variable is a container in a computer program that stores a value which can be changed later. A variable is usually assigned a name to identify it, such as “x” or “username”. In programming, variables are used to store values such as numbers, text, or other data types.
Data Types
Data types define the type of data that can be stored in a variable. Some common data types include:
- Integer (e.g. 1, 2, 3)
- Float (e.g. 1.0, 2.5, 3.14)
- String (e.g. “Hello World!”, “John Doe”)
- Boolean (e.g. True, False)
Operators
Operators are symbols that perform operations on variables and values. Some common operators include:
- Arithmetic operators (+, -, *, /)
- Comparison operators (>, <, >=, <=, ==, !=)
- Logical operators (and, or, not)
Conditional Statements
Conditional statements are used to execute a specific block of code based on whether a certain condition is met. The most common type of conditional statement is an if statement.
For example:
The code inside the if statement will only be executed if the condition x > 0 is true. If the condition is false, the code inside the else statement will be executed instead.
Hello, World!
The “Hello, World!” program is a simple program that displays the message “Hello, World!” on the screen. It is a great place to start for absolute beginners.
Tips for writing your first program
When writing your first program, keep these tips in mind:
Start with a simple program.
Take your time and don’t rush through the process.
Make sure to understand each line of code and how it works.
Break the problem down into smaller parts and tackle each part one at a time.
Use comments in your code to explain what each section does. This will help you understand the code later on and also make it easier for others to understand if they ever need to work on the code.
Use online resources and forums for help if you get stuck. There is a wealth of information available online, and many experienced coders are happy to help beginners.
Test your code regularly to make sure it is working as expected. If something isn’t working, go back and debug the code to find the problem.
Celebrate your successes! Even small achievements are worth celebrating as they will help build your confidence and motivate you to keep learning.

Give 3 practice beginner code exercises
- Fizz Buzz: Write a program that prints the numbers from 1 to 100. But for multiples of three print “Fizz” instead of the number and for the multiples of five print “Buzz”. For numbers which are multiples of both three and five print “FizzBuzz”.
Explanation: In this program, we are using a for loop to iterate through the numbers 1 to 100. The if statement checks if the number is a multiple of both 3 and 5, and if so, it prints “FizzBuzz”. If it’s only a multiple of 3, it prints “Fizz”, and if it’s only a multiple of 5, it prints “Buzz”. If none of the conditions are met, the program prints the number.
- Reverse a string: Write a program that takes a string as input and returns its reverse.
Explanation: In this program, we defined a function reverse_string that takes a string as input and returns its reverse. We are using slicing to reverse the string, by using the syntax s[::-1]. The input_string variable is set to “hello”, and the program outputs the reverse of the string, which is “olleh”.
- Palindrome check: Write a program that checks if a given string is a palindrome (a word that reads the same backward as forward).
Explanation: In this program, we defined a function is_palindrome that takes a string as input and returns True if it is a palindrome, and False otherwise. The program uses the slicing method as in the previous example, but instead of returning the reverse of the string, it compares it to the original string. If the two are the same, it returns True, indicating that the input string is a palindrome. The input_string variable is set to “racecar”, and the program outputs True, indicating that the string is a palindrome.
3 Beginner Code Exercises for Building a Website
Building a Simple Website:
Create a basic website with a title, header, and body text.
Explanation: This is a basic HTML file that creates a website with a title, header, and body text. The <!DOCTYPE html> declaration specifies the type of document being used, in this case, HTML5. The <html> element is the root element of the document and contains all other elements. The <head> element contains information about the document, such as the title, which is displayed in the browser tab. The <body> element contains the content that is displayed on the page, including a header with <h1> and a paragraph with <p>.
Adding a stylesheet:
Create a stylesheet to add style to the website.
Explanation: In this example, we added a stylesheet to our website to add some style. The <link> element in the <head> section of the HTML file references the stylesheet file, which is named “style.css” in this example. The CSS file contains styles for the header and paragraph elements. The h1 selector sets the color to blue and aligns the text to the center, while the p selector sets the font size to 18px and aligns the text to be justified.
Adding a navigation bar:
Create a navigation bar with links to other pages on the website.
Explanation: In this example, we added a navigation bar to our website. The `<nav>` element is used to define a section for the navigation bar. Within the `<nav>` element, we use an unordered list `<ul>` to list the navigation links. Each navigation link is defined as a list item `<li>` and is wrapped in an anchor tag `<a>` with a specific `href` attribute that refers to the corresponding page on the website. The CSS file contains styles for the navigation bar, such as a light gray background color, the links being displayed in a row with equal spacing between them, and the links being black and not underlined.
