12. Python focus Duck Typing List comprehension

13. Duck Typing class Duck: def quack(self): print("Quaaaaaack!") class Person: def quack(self): print("The person imitates a duck.") defin_the_forest(duck): duck.quack() def game(): donald = Duck() john = Person() in_the_forest(donald) in_the_forest(john) game()

14. List Comprehension What would be the values of listB? listA = [j for i in range(2, 8) for j in range(i*2, 50, i)]listB = [x for x in range(2, 50) if x not in listA] [2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47]

15. What about IronPython?

16. IronPython Goals True Python Implementation Seamless integration with .NET

17. IronPython is: Open source Supports both .NET & Mono All CLR types are available Can call .NET code

18. IronPython IDEs VS2010 + IronPython extension #Develop Wing Eclipse + PyDev For more details see: http://www.voidspace.org.uk/ironpython/tools-and-ides.shtml

19. The interactive shell Run code on the fly Run .NET code on the fly >>> print "Hello, world" Hello, world >>> x = 12**2 >>> x/2 72 >>> # this is a comment
