In this case, the named arguments must come after the positional arguments. It is also possible to specify only some of the optional arguments of a function, regardless of their order.

In the definition, the parameter list is sometimes referred to as the formal parameters or parameter names. These names can be any valid variable name. If there is more than one, they are separated by commas. In the function invocation, inside the parentheses one value should be provided for each of the parameter names.

Parameters allow you to pass values into a function so that the function can perform its task using those values.

February 3, 2023 -
I am trying really hard to understand specifically parameters. Particularly, when I define a function I.e. def function(parameter): print(parameter) And then call it function("a simple string") Is the parameter always going to be parameter? It's receiving a value, right? So... Maybe I'm like mentally deficit... or overthinking this, but what if I do..
def function(parameter0, parameter1, parameter3)
print(parameter0, parameter1, parameter3)And then call the function
function("Does this cause an error?", "Must have exact values", "for each parameter?")Am I over thinking this? I'm just following lessons from a PDF. Python for the absolute beginner
I'm must confused and I'm not even sure how or why I'm confused.

Edit: formatting and typos

Update: Thanks everyone for your help. I think I am understanding it. I believe I'm overthinking it, and over reacting. Sorry for being difficult.

So, taking a swing at it....the parameter(s) in Python are just a way of telling the function that it should be receiving one or more objects/pieces of information. How you write the function determines what type of object those things need to be. Per your example, def funct(param): print(param) Can be used with any type of object that can be printed out to the console; like: func(23) func("Hello, Timmy") will print out the value 23, and then the string "Hello, Timmy" What this, also, means is that you can assign things to variables and pass those variables in to the parameter spot (referred to as an argument when calling the function) and they will still be the object/type of object that you assigned earlier. a = [2, 5, 7, 9] func(a) will print [2, 5, 7, 9] out to the console. Does that help?

Everything in Python is an object (including integers, lists, functions, classes, etc) Variables are just names that refer to objects An object can have several names that refer to it, but each name can only directly refer to a single object (although that object can be a collection of other objects, like in a list or tuple) An area of code where a set of names is accessible is called a namespace (modules (files) and functions both hold a local namespace, and a function can access its local namespace as well as the global namespace of the module it’s being called in) When defining a function, the parameters define the names of the objects that get passed in to its local namespace (regardless of any extra names that may refer to those objects outside a function call), so those names can be used throughout the function (but are not accessible from outside the function) When calling a function the parameters are used to pass in objects this can be positionally, as in your example, or as keyword-arguments that specify which parameter name should be assigned to which object (e.g. my_func(a, 3, param=[], param8=var)) it doesn’t matter if the objects are passed in as literals (e.g. 3, "string") or variables - just the object (the “value”) is passed in and bound to the relevant parameter name Python interprets code from top to bottom If you define a new function with the same name as some other object, then that name now refers to that function, and has no memory of what it used to refer to (just like if you do a=3 and then later in your code do a=4)

A parameter is a variable in a method definition. When a method is called, the arguments are the data you pass into the method's parameters.
public void MyMethod(string myParam) { }
...
string myArg1 = "this is my argument";
myClass.MyMethod(myArg1);

Parameter is the variable in the declaration of the function.
Argument is the actual value of this variable that gets passed to the function.

However, it's often useful to set a different default value. This is where default parameters can help. In the following example, if no value is provided for b when multiply is called, b's value would be undefined when evaluating a * b and multiply would return NaN.
