The function def function_name(arg1.arg2,....argN): statements return results A Simple Python Function Needless to say that the statements and the return command should form an indented block. Consider a simple function that returns the sum of the input values. It is realized as the function below. def summ(x,y): return x+y Unlike MATLAB or IDL, it is possible to execute a function in the Python shell. You may type the above function in a Python shell or an enhanced Python shell such as IPython. Once the function is executed, if you type summ(7,4), it re...
