  • Difficulty Level : Medium
  • Last Updated : 16 Sep, 2020

Prerequisite – Tuples and Dictionaryin Python
Predict the output of the following Python programs.

  1. What is the output of the following program?




    numberGames = {}
    numberGames[(1,2,4)] = 8
    numberGames[(4,2,1)] = 10
    numberGames[(1,2)] = 12
       
    sum = 0
    for k in numberGames:
        sum += numberGames[k]
       
    print len(numberGames) + sum

    
    

    Output:

    33
    

    Explanation:
    Tuples can be used for keys into dictionary. The tuples can have mixed length and the order of the items in the tuple is considered when comparing the equality of the keys.

  2. What is the output of the following program?




    my_tuple = (1, 2, 3, 4)
    my_tuple.append( (5, 6, 7) )
    print len(my_tuple)

    
    

    Output:

    Error !
    

    Explanation:
    Tuples are immutable and don’t have an append method as in case of Lists.Hence an error is thrown in this case.

  3. What is the output of the following program?




    t = (1, 2)
    print 2 * t

    
    

    Output:

    (1, 2, 1, 2)
    

    Explanation:
    Asterick Operatr (*) operator concatenates tuple.



  4. What is the output of the following program?




    d1 = {"john":40, "peter":45}
    d2 = {"john":466, "peter":45}
    print (d1 > d2)

    
    

    Output:

    TypeError
    

    Explanation:
    The ‘>’ operator is not supported between instances of ‘dict’ and ‘dict’.

  5. What is the output of the following program?




    my_tuple = (6, 9, 0, 0)
    my_tuple1 = (5, 2, 3, 4)
    print my_tuple > my_tuple1

    
    

    Output:

    True
    

    Explanation:
    Each elements of the tuples are compared one by one and if maximum number of elements are there in tuple1 which are greater of equal to corresponding element of tuple2 then tuple1 is said to be grater than tuple2.
