Which of the following statements correctly describes the process of deleting an entry from a Python dictionary?

• To remove an entry from a Python dictionary, use the remove() method with the dictionary name and the key as arguments.

• To eliminate an entry from a Python dictionary, use the pop() method with the dictionary name and the key in parentheses.

• To erase an entry from a Python dictionary, utilize the discard() function followed by the dictionary name and the key.

• To delete a specific entry from a Python dictionary, simply assign None to the key you want to remove.

• To delete an entry from a Python dictionary, use the del statement followed by the dictionary name and the key in square brackets.

Which of the following statements accurately highlights a key difference between tuples and lists in Python?

• Tuples are immutable, while lists are mutable.

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

• Both tuples and lists are mutable data structures that can be modified freely.

• Lists are immutable, whereas tuples are mutable and can be altered.

• Tuples and lists have the same properties regarding mutability and can be changed at any time.

Which of the following statements correctly describes the process of creating a tuple in Python?

• A tuple in Python is formed by listing values without any parentheses, separated by commas, and a single-element tuple must be defined with a single value only.

• A tuple in Python is constructed by using parentheses for multiple values, separated by spaces, and requires a colon after the first value for identification as a tuple.

• A tuple in Python is created by placing a sequence of values within parentheses, separated by commas, and requires a trailing comma for single-element tuples.

• A tuple in Python can be created using braces to enclose values, separated by commas, and a trailing comma is mandatory for all tuples regardless of the number of elements.

• A tuple in Python is created by enclosing values in square brackets, separated by semicolons, and does not require any additional punctuation for single-element tuples.

Given a tuple named "fruits" defined as ("apple", "banana", "cherry", "banana", "date"), which of the following statements correctly demonstrates the use of the tuple methods count() and index() to find the occurrences of "banana" and the first position of "cherry" in the tuple?

• fruits.index("banana", 1), fruits.count("cherry")

• fruits.count("banana", 1), fruits.index("date")

• fruits.index("banana"), fruits.count("cherry")

• fruits.count("date"), fruits.index("banana")

• fruits.count("banana"), fruits.index("cherry")

Given the Python dictionary defined as dict = { 'Name' : 'Zara', 'Age' : 7, 'Class' : 'First' }, which of the following options correctly represents the dictionary after adding a new entry for 'School' with the value "DPS School" and updating the 'Age' to 8?

• { 'Name' : 'Zara', 'Class' : 'First', 'School' : 'DPS School', 'Age' : 8 }

• { 'Name' : 'Zara', 'Age' : 9, 'Class' : 'First', 'School' : 'DPS School' }

• { 'Name' : 'Zara', 'Age' : 8, 'Class' : 'First', 'School' : 'DPS School' }

• { 'Name' : 'Zara', 'Age' : 8, 'Class' : 'First', 'School' : 'School A' }

• { 'Name' : 'Zara', 'Age' : 7, 'Class' : 'First', 'School' : 'DPS Academy' }

Which of the following statements accurately describes the use of Python dictionary methods, specifically focusing on keys(), values(), items(), get(), pop(), popitem(), update(), clear(), and copy()?

• Python dictionary methods like keys(), values(), items(), get(), pop(), popitem(), update(), clear(), and copy() serve to encrypt the data stored within the dictionary for security purposes.

• Python dictionary methods such as keys(), values(), items(), get(), pop(), popitem(), update(), clear(), and copy() provide essential functionalities for accessing, modifying, and managing key-value pairs efficiently.

• Python dictionary methods including keys(), values(), items(), get(), pop(), popitem(), update(), clear(), and copy() mainly focus on sorting the keys and values in ascending order.

• Python dictionary methods such as keys(), values(), items(), get(), pop(), popitem(), update(), clear(), and copy() are designed to convert dictionaries into lists for easier manipulation.

• Python dictionary methods like keys(), values(), items(), get(), pop(), popitem(), update(), clear(), and copy() are primarily used for creating new dictionaries from existing ones.

When creating a Python dictionary, which of the following statements is true regarding the properties of keys and values in relation to their uniqueness and data types?

• Keys can be duplicated and must be of a mutable type, while values must always be of the same data type.

• Keys can be of any data type, including mutable types, while values must be unique and of an immutable type.

• Keys must be unique but can be mutable, while values are required to be unique and of an immutable type.

• Keys must be unique and immutable, while values can be of any data type, which can include duplicates.

• Keys must be unique and can be of any type, while values must be immutable and can include duplicates.

Which of the following statements is true regarding the use of tuples as keys in Python dictionaries?

• Tuples can be used as keys in Python dictionaries, but they must contain only one element.

• Tuples cannot be used as keys in Python dictionaries because they are mutable.

• Tuples are not suitable as keys in Python dictionaries since they must be of integer type.

• Tuples can serve as keys in Python dictionaries, but only if they are empty.

• Tuples can be used as keys in Python dictionaries because they are immutable.
