the actual parameters in the function call are evaluated left to rightand then these values are associated with the formal parameter names in the function definitionalso left to right for example function call with actual parametersf(actual actual actual )calling function with definition headingdef (formal formal formal )acts approximately as if the first lines executed inside the called function were formal actual formal actual formal actual functions provide extremely important functionality to programsallowing tasks to be defined once and performed repeatedly with different data it is essential to see the difference between the formal parameters used to describe what is done inside the function definition (like and in the definition of sumproblemand the actual parameters (like and or and which substitute for the formal parameters when the function is actually executed the main method above uses three different sets of actual parameters in the three calls to sumproblem quotient function exercise the example addition py is modification of addition pyputting the arithmetic problem into function and then calling the function several times with different parameters similarly modify quotientformat py from quotient format exercise (page and save it as quotientprob py you should create function quotientproblem with numerical parameters like in all the earlier versionsit should print full sentence containing the inputsquotientand remainder the main method in the new program should test the quotientproblem function on several sets of literal valuesand also test the function with input from the user returned function values you probably have used mathematical functions in algebra classthey all had calculated values associated with them for instance if you defined ( )= then it follows that ( is and ( )+ ( is function calls in expressions get replaced during evaluation by the value of the function the corresponding definition and examples in python would be the followingtaken from example program return py read and run''' simple function returning valueused in an expression''def ( )return * print( ( )print( ( ( )the new python syntax is the return statementwith the word return followed by an expression functions that return values can be used in expressionsjust like in math class when an expression with function call is evaluatedthe function call is effectively replaced temporarily by its returned value inside the python function definitionthe value to be returned is given by the expression in the return statement after the function finishes executing from inside print( ( ) beginning with python
