Before jumping into the cool world of programming languages like Python and JavaScript, Year 9 students should know some basic programming ideas. Let’s take a closer look at these important building blocks:

1. Variables

Understanding variables is super important.

Think of a variable as a container that holds information.

For example, in Python, you might make a variable to store a student's name like this:

student_name = "Alice"

2. Data Types

Programming languages work with different kinds of data. Here are some types you should know:

• Integers (whole numbers): like 5, -3
• Floats (numbers with decimals): like 3.14, -0.001
• Strings (words or text): like "Hello, World!"
• Booleans (true or false): like True, False

3. Control Structures

Control structures help decide how your programs run. For example:

• Conditionals help make choices. Here’s how you might check if someone can vote:

  if student_age >= 18:
      print("You can vote!")
  

• Loops let you repeat tasks, like counting. Here’s an example:

  for i in range(5):
      print(i)
  

4. Functions

Functions are like little helpers in your code. They are blocks of code that do specific things. For example:

def greet(name):
    return "Hello, " + name

Conclusion

By learning these basic ideas, Year 9 students will have a strong base to explore programming languages like Python and JavaScript.

Happy coding!
