To get a sub tuple out of the tuple, we need to specify the range of indexes.  We need to specify where to start and where to end the range.

Syntax: tuple[start:end] If the start is missing it takes 0 as the starting index.

A Python tuple can also be created without using parentheses

• False

• True

Answer explanation

What is the output of the following tuple operation

thistuple = (100,)

print(thistuple * 2)

• • (100, 100)

• Error

What is the type of the following variable

thistuple = ("Orange")

print(type(thistuple))

• int
• list
• str
• float

Answer explanation

To create a tuple with a single item, you need to add a comma after the item. Otherwise, Python will not recognize the variable as a tuple, and it will treat it as a string type.

What is the output of the following

aTuple = "Yellow", 20, "Red"

a, b, c = aTuple

print(a)

• Yellow
• aTuple
• Red
• 20

Answer explanation

The tuple unpacking is also possible

What is the output of the following code

aTuple = (100, 200, 300, 400, 500)

aTuple[1] = 800

print(aTuple)

• Error
• (100, 200, 300, 400, 800)
• (100, 200, 800, 400, 500)
• (100, 800, 300, 400, 500)

Answer explanation

A tuple is immutable. Once a tuple is created, you cannot change its values. If you try to change its value, you will receive a  TypeError: 'tuple' object does not support item assignment

What is the output of the following code

aTuple = (100, 200, 300, 400, 500)

print(aTuple[-2])

print(aTuple[-4:-1])

• Error as it is out of range

• 400
  (200, 300, 400)

• (300, 400, 500)
• 400, 300, 200

Answer explanation
