Chapter Summary

--- PAGE 1 --- CHAPTER 10 TUPLES AND DICTIONARIES 10.1 INTRODUCTION TO TUPLES A tuple is an ordered sequence of elements of different data types, such as integer, float, string, list or even a tuple. Elements of a tuple are enclosed in parenthesis (round brackets) and are separated by commas. Like list and string, elements of a tuple can be accessed using index values, starting from 0. Example 10.1 #tuple1 is the tuple of integers >>> tuple1 = (1,2,3,4,5) >>> tuple1 (1, 2, 3, 4, 5) #tuple2 is the tuple of mixed data types >>> tuple2 = ('Economics',87,'Accountancy',89.6) >>> tuple2 ('Economics', 87, 'Accountancy', 89.6) #tuple3 is the tuple with list as an element >>> tuple3 = (10,20,30,[40,50]) >>> tuple3 (10, 20, 30, [40, 50]) #tuple4 is the tuple with tuple as an element >>> tuple4 = (1,2,3,4,5,(10,20)) >>> tuple4 (1, 2, 3, 4, 5, (10, 20)) If there is only a single element in a tuple then the element should be followed by a comma. If we assign the value without comma it is tre…
