Hi, words = ['cat', 'window', 'defenestrate']
here words is a list and each element in that list can be accessed via index. words[0] will give cat words[1] will give window for more information on list : http://docs.python.org/2/tutorial/introduction.html#lists also in python for loop is quite from different from other programming languages. for more information on for loop : http://docs.python.org/2/tutorial/controlflow.html#for-statements for w in words: for the first loop ,the value in words[0] is picked and assigned to w , i.e w = words[0] for the second loop ,the value in words[1] is picked and assigned to w , i.e w = words[1] .....so on It is always better to have understanding of what data type we are working on and then what are the operation we are performing. I hope that you are clear about working of for loop.
