Using parameters in functions is like giving your functions a special touch. They help your functions do specific jobs based on the information you give. Here’s how you can use them well:

1. What Are Parameters?

• Parameters are like little boxes where you can put values when you use a function.
• They help make your functions reusable. Instead of writing the same code for different numbers or words, you can change the parameters to get different results.

2. Defining Parameters:

• When you create a function, make sure to clearly define your parameters at the beginning. For example, in Python, you might write something like this:

  def greet(name):
      print("Hello, " + name + "!")
  

• Here, name is a parameter that makes the greeting personal.

3. Using Multiple Parameters:

• You can have more than one parameter to give your function even more abilities. For example:

  def add(a, b):
      return a + b
  

• In this case, a and b are parameters that let you add any two numbers you choose.

4. Default Values:

• You can also use default values for parameters to make things easier:

  def power(base, exponent=2):
      return base ** exponent
  

• If you don’t provide a value for exponent, it will just use 2.

By getting good at using parameters, you’ll make your functions work better and your code easier to read and understand!
