Akansha Yadav explains parameters as placeholders in Python functions that let you pass different values when calling them. She shows how to define parameters in parentheses with an add(a, b) example, then covers the asterisk syntax for accepting any number of arguments.
Ladies and gentlemen, as I told you that in this case name was a parameter, in this case number was a parameter. So it is not limited to this only. So the parameters are something like a placeholder for that value that function will receive when it is called. It means whenever you are going to call that function, it will receive some values with that function, and that function will— that value will be called as a parameter. So it allows the function to accept the input, making them versatile. It is applicable to the various scenarios and the situations or whatever things you are going to— wherever you are going to implement it. So parameters are defined within the parenthesis following up with the names. So it's not limited to 1, 2, 3, as many numbers you wanted to write, you can. So let's write an addition program using function. So let's say if I'm saying def add, I'm writing a, b because I need two numbers. Now I want addition of— add is equal to a plus b. Now I want it to return add. So whenever I will call it, I will write two numbers, 25 comma 26, and we are getting the output as an addition as well. So as many numbers, as many parameters you wanted to write, you can write. Even though if you're not sure about how many parameters you're going to use, so you can just write the asterisk symbol and the key. So that is what the parameter is in Python. Functions.
