A parameter in programming is like a placeholder for a value that you want to use in a function or method. Think of a function or method as a recipe that you can follow to get a specific result. Just like a recipe might ask you to add a certain amount of ingredients, a function or method will ask you to provide certain values (parameters) that it can use to perform its task.
For example, consider a simple function that adds two numbers together:
pythonCopy code
def add(a, b):
return a + b
Here, a and b are the parameters of the function. When you call the function, you can provide values for a and b, and the function will use those values to perform its task. For example:
scssCopy code
result = add(2, 3)
print(result) # Output: 5
In this example, the values 2 and 3 are passed as arguments to the function, and they are stored in the parameters a and b respectively. The function then performs its task of adding a and b together and returns the result, which is 5.
