Statement: statement o, return [value1[, value2, ]] Note: when reading computer notation, the square brackets are used to denote optional items. Case 1: a function does not return any values: def function_name ([parameter1[, parameter2, ]]): Return: # function definition must appear before the call o # function is not executed until you call it, function_name ([argument1[, argument2, ]]) Case 2: a function returns a value: def function_name ([parameter1[, parameter2, ]]): Return value: # function definition must appear before the call o # function is not executed until you call it, variable = function_name([argument1[,arg2, ]]) Case 3: a function returns more than one value: def function_name ([parameter1[, parameter2, ]]): Return value1, value2: # function definition must appear before the call o # function is not executed until you call it, var1, var2 = function_name ([arg1[, arg2, ]])
