Understanding Python Data Structures

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.

How do you create a tuple in Python?

• Using square brackets, e.g., [1, 2, 3]

• Defining a tuple with the tuple() function, e.g., tuple(1, 2, 3)

• Creating a list with curly braces, e.g., {1, 2, 3}

• You create a tuple in Python by using parentheses, e.g., (1, 2, 3).

Can tuples be modified after creation?

• No, tuples cannot be modified after creation.

• Tuples can have their elements changed after creation.

• Tuples can be resized after creation.

• Yes, tuples can be modified after creation.

What is the main difference between a tuple and a list?

• The main difference is that tuples are immutable and lists are mutable.

• Tuples are created using square brackets, while lists use parentheses.

• Lists can contain only numbers, while tuples can contain any data type.

• Tuples can be resized, while lists cannot.

How do you access elements in a tuple?

• Use indexing with square brackets, e.g., tuple_name[index].

• Elements can only be accessed by iterating through the tuple.

• Use curly braces to access elements, e.g., tuple_name{index}.

• Access elements using parentheses, e.g., tuple_name(index).

What is a set in Python?

• A set is an ordered collection of elements in Python.

• A set is an unordered collection of unique elements in Python.

• A set can contain duplicate elements in Python.

• A set is a type of list in Python.

How do you create a set in Python?

• You can create a set in Python using set() or by using curly braces, e.g., set() or {1, 2, 3}.

• Defining a dictionary with curly braces, e.g., {key: value}

• Using square brackets, e.g., [1, 2, 3]

• Creating a list with list() function

Can sets contain duplicate elements?

• Sets can contain only one element.

• Yes, sets can contain duplicate elements.

• No, sets cannot contain duplicate elements.

• Sets can contain elements of different data types.

What is the main difference between a set and a list?

• A set can contain duplicates and is ordered, while a list cannot.

• The main difference is that a set contains only unique elements and is unordered, while a list can contain duplicates and is ordered.

• A list is always unordered and contains only unique elements.

• A set is a type of list that allows for ordering of elements.

How do you add an element to a set?

• Use the 'add' method.

• Use the 'push' method.

• Use the 'append' method.

• Use the 'insert' method.
