hellohellohellohellohello aaaaaaaaaa returning values we can write functions that perform calculations and return result example here is simple function that converts temperatures from celsius to fahrenheit def convert( )return * / + print(convert( ) the return statement is used to send the result of function' calculations back to the caller notice that the function itself does not do any printing the printing is done outside of the function that waywe can do math with the resultlike below print(convert( )+ if we had just printed the result in the function instead of returning itthe result would have been printed to the screen and forgotten aboutand we would never be able to do anything with it example as another examplethe python math module contains trig functionsbut they only work in radians let us write our own sine function that works in degrees from math import pisin def deg_sin( )return sin(pi* / example function can return multiple values as list say we want to write function that solves the system of equations ax and it turns out that if there is unique solutionthen it is given by (de )/(ad bcand ( ce)/(ad bcwe need our function to return both the and solutions def solve( , , , , , ) ( * - * )/( * - *cy ( * - * )/( * - *creturn [ ,
