Parameter
A parameter is a programming variable or value that transfers data between functions. Functions, which are self-contained blocks of code that perform specific tasks, receive input data (arguments) through parameters. By allowing functions to accept different types of arguments, parameters enhance the adaptability and reusability of functions, allowing for dynamic and interactive web page and application development.
Here's an example of a code snippet with parameters, functions, and arguments:
def addNumbers(num1, num2, num3)
sum = num1 + num2 + num3
return sum
In this example, num1, num2, and num3 are parameters, while sum is the function. Now, let’s add arguments.
result = addNumbers (5, 10, 15)
print(result) # Output: 30
The numbers 5, 10, and 15 are arguments. They’re assigned to the parameters num1, num2, and num3, providing an output when given the sum function. Similarly, the function is reusable and will return results for any parameters and arguments it receives.
