Python Tuples Test - 2

1. What is the data type of (1)?

Integer

Tuple

Both tuple and integer

List

2. What will be the output of the following Python code?

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

(‘Check’,’Check’,’Check’)

Syntax error

* Operator not valid for tuples

(‘CheckCheckCheck’)

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

Array of tuples

Tuples of lists

List of tuples

Invalid type

4. What will be the output of the following Python code?

>>> a=(0,1,2,3,4)
>>> b=slice(0,2)
>>> a[b]

(0,2)

Invalid syntax for slicing

(0,1)

[0,2]

5. Is the following Python code valid?

>>> a=(1,2,3)
>>> b=('A','B','C')
>>> c=tuple(zip(a,b))

Yes, c will be ((1,2,3),(‘A’,’B’,’C’))

No because tuples are immutable

No because the syntax for zip function isn’t valid

Yes, c will be ((1, 'A'), (2, 'B'), (3, 'C'))

6. Is the following Python 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

7. What will be the output of the following Python code?

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

The method sum() doesn’t exist for tuples

Too many arguments for sum() method

8. What will be the output of the following Python code?

>>> a=(1,2,(4,5))
>>> b=(1,2,(3,4))
>>> a<b

Error, < operator is not valid for tuples

False

Error, < operator is valid for tuples but not if there are sub-tuples

True

9. If a=(1,2,3,4), a[1:-1] is _________

[2,3]

(2,3)

Error, tuple slicing doesn’t exist

(2,3,4)

10. What will be the output of the following Python code?

>>> a=(1,2,3,4)
>>> del(a[2])

Now a=(3,4)

Error as tuple is immutable

Now, a=(1,2,4)

Now, a=(1,3,4)
