Python - List and Tuples

What is the output of the following piece of code when executed in Python shell?

>>> a=("Check")*3

>>> a

• (‘Check’,’Check’,’Check’)

• * Operator not valid for tuples

• (‘CheckCheckCheck’)

• Syntax error

Is the following piece of code valid?

>>> a=(1,2,3,4)

>>> del a

• No because tuple is immutable

• Yes, the entire tuple is deleted

• No, invalid syntax for del method

• Yes, first element in the tuple is deleted

What type of data is: a=[(1,1),(2,4),(3,9)]?

• Array of tuples

• List of tuples

• Tuples of lists

• Invalid type

Which of the following is true for a tuple?

• Tup = 1,2,3

• Tup = (""1,"2)

• Tup = (1,2,3,4)

• None of the above

Result of the program above is

• ('1', '2', '3', '4', '5')

• (1, 2, 3, 4, 5)

• 12345

• "12345"

Suppose you have the following tuple definition:

t = ('foo', 'bar', 'baz')

Which of the following statements replaces the second element ('bar') with the string 'qux':

• t[1] = 'qux'

• t(1) = 'qux'

• t[1:1] = 'qux'

• error

If list=[17,23,41,10] then list.append(32) will result

• [32,17,23,41,10]

• [17,23,41,10,32]

• [10,17,23,32,41]

• [41,32,23,17,10]

Suppose list=[12,3,22,"mago","hello"], what is list[-6]

• Error

• None

• mango

• 12

L_names=['Harsh','Amit','Sahil','Viresh']

min(L_names)

• 'Harsh'

• 'Amit'

• 'Viresh'

• None of the above

L_names=['Harsh','Amit','Sahil','Viresh']

L_names.pop()

• 'Harsh'

• 'Amit'

• 'Viresh'

• None of the above
