Python Tuple-02

What is a tuple in Python?

• A tuple is defined by items in square brackets.

• A tuple can be modified after creation.

• A tuple is a mutable sequence type in Python.

• A tuple is an immutable sequence type in Python, defined by items in parentheses.

List the operation that can be performed on tuples.

• reverse()

• sort()

• index()

• append()

How do tuples differ from lists in Python?

• Tuples can hold only one data type, while lists can hold multiple types.

• Tuples can be modified after creation, while lists cannot.

• Tuples are immutable and defined with (), while lists are mutable and defined with [] in Python.

• Lists are defined with (), while tuples are defined with [].

Explain the concept of immutability in tuples.

• Tuples are mutable collections of elements.

• Tuples can be modified after creation.

• Immutability in tuples means that their elements cannot be modified after creation.

• Immutability allows tuples to change their size.

What is a nested tuple? Provide an example.

• (1, 2, 3, 4)

• ((1, 2), (3, 4), (5, 6))

• ([1, 2], [3, 4])

• ([1, 2], 3, 4, 5)

How do you access elements in a nested tuple?

• Access elements using t[i,j] syntax.

• Use indexing like t[i][j] for nested tuples.

• Convert the tuple to a list before accessing elements.

• Use a for loop to iterate through the tuple.

What will happen if you try to append an item to a tuple?

• The item will be added without any issues.

• An error will occur (AttributeError) because tuples are immutable.

• The tuple will convert to a list and allow appending.

• The tuple will automatically resize to accommodate the new item.

What is the syntax for creating a tuple in Python?

• A tuple is created using square brackets, e.g., [1, 2, 3].

• A tuple is created using curly braces, e.g., {1, 2, 3}.

• A tuple is created using angle brackets, e.g., <1, 2, 3>.

• A tuple is created using parentheses, e.g., (1, 2, 3).

What method can be used to find the index of an element in a tuple?

• find()

• index()

• search()

• locate()

What will be the output of the expression (1, 2) + (3, 4)?

• (1, 2, 3, 4)

• (1, 2)(3, 4)

• Error: Cannot concatenate tuples.

• (1, 2, (3, 4))
