Functional programming with Python

To work with lists many c/c++ programmer use a simple for-loop. I will try to explain how this can be made a little bit easier. For that I use the self-explaining script language python.

Here is a simple example to filter all odd integers from a list in simple python 2.x syntax.

def filter_odd(myList):  

   result = []               # initialize the result list  

   for num in myList:               # iterate over the list  

     if num % 2 == 1:        # modulo 2 return 1 for odd integers

        result.append(num)   # add to the result

   return result
