The function body is then indented and contains the code to be executed. # Here's an example of a simple Python function that takes two arguments and returns their sum: def add_numbers(a, b): sum = a + b return sum add_numbers(4,5) # calling the function # without calling the function cannot run #2 Arguments in python -- whatever variable is used inside a function during the defining of the function is called a formal argument. -- whatever value you passed during the calling is called actual arguments. #3 -- The return statement is used to exit a function and return a value. -- The return statement can be used to return a value from a function. -- The return statement can also be used to exit a function without returning a value. -- If the return statement is without any expression, then the special value None is returned. -- Functions without a return statement return None as their result. def add_sub(x,y): c = x+y d = x-y return c,d result1,result2 = add_sub(4,5) print(result1,result2) # The above code defines a Python function called add_sub that takes two input arguments x and y. The function first adds x and y and stores the result in a variable called c. It then subtracts y from x and stores the result in a variable called d. Finally, it returns both c and d as a tuple. # The function can be called with two arguments, as shown in the line result1,result2 = add_sub(4,5). This line assigns the values returned by the add_sub function to the variables result1 and result2, respectively. The print statement then outputs the values of result1 and result2 to the console.
