Only one value is passed during the function call. So, according to the positional argument2is assigned to argumenta, and the default value is used for parameterb. 3. add_number() No value is passed during the function call. Hence, default value is used for both parametersaandb. Python ...
5. Python Function Unknown Number of Parameters NOTE: If there are, say 4 parameters in a function and a default value is defined for the 2nd one, then 3rd and 4th parameter should also be assigned a default value. If the number of parameters a function should expect is unknown, then *...

1. Python Required ParametersIf we define a function in python with parameters, so while calling that function –it is must send those parameters because they are Required parameters.Example# Required parameter def show(id,name): print("Your id is :",id,"and your name is :",name) show(...
When, we call a function with the reference/object, the values of the passing arguments can be changes inside the function. Example 1: Calling function by passing the object to the class classmydata:def__init__(self):self.__data=0defsetdata(self,value):self.__data=valuedefgetdata(self)...
By default, a function must be called with the correct number of arguments. Meaning that if your function expects 2 arguments, you have to call the function with 2 arguments, not more, and not less. Example This function expects 2 arguments, and gets 2 arguments: ...
