// Quiz questions database
const questions = [
{
question: "What is the output of the following Python code?",
code: "print(2 + 2 * 3)",
options: ["8", "10", "12", "6"],
answer: 0,
explanation: "In Python, multiplication has higher precedence than addition. So 2 * 3 is calculated first (resulting in 6), then 2 + 6 is calculated, giving 8."
},
{
question: "Which of the following is used to create a virtual environment in Python?",
code: "",
options: ["venv", "virtualenv", "pipenv", "All of the above"],
answer: 3,
explanation: "All of these tools can be used to create virtual environments in Python. venv is built into Python 3, virtualenv is a third-party tool, and pipenv combines virtual environment management with package management."
},
{
question: "What does the 'yield' keyword do in Python?",
code: "",
options: [
"Returns a value and terminates the function",
"Pauses the function and returns a generator object",
"Used for exception handling",
"Defines a static method"
],
answer: 1,
explanation: "The yield keyword is used in generator functions to pause execution and return a value. When called again, the function resumes where it left off."
},
{
question: "What is the output of the following code?",
code: "x = [1, 2, 3]\ny = x\ny.append(4)\nprint(x)",
options: ["[1, 2, 3]", "[1, 2, 3, 4]", "[4]", "Error"],
answer: 1,
explanation: "When we assign y = x, both variables point to the same list in memory. So modifying y also modifies x."
},
{
question: "Which method would you use to remove the last element from a list?",
code: "",
options: ["list.remove()", "list.pop()", "list.delete()", "list.cut()"],
answer: 1,
explanation: "The pop() method removes and returns the last element by default. You can also specify an index to remove an element at a specific position."
},
{
question: "What is the purpose of __init__ in a Python class?",
code: "",
options: [
"To initialize the class object",
"To create class methods",
"To define class variables",
"To terminate the class instance"
],
answer: 0,
explanation: "The __init__ method is called when a new instance of a class is created. It's used to initialize the object's attributes."
},
{
question: "What does the 'with' statement do?",
code: "",
options: [
"Creates a loop",
"Handles exceptions",
"Manages resources and ensures cleanup",
"Defines a context for variable scope"
],
answer: 2,
explanation: "The 'with' statement simplifies resource management by ensuring that setup and cleanup operations are performed automatically."
},
{
question: "What is the output of the following code?",
code: "print([i for i in range(10) if i % 2 == 0])",
options: [
"[0, 2, 4, 6, 8]",
"[2, 4, 6, 8]",
"[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]",
"[1, 3, 5, 7, 9]"
],
answer: 0,
explanation: "This list comprehension generates numbers from 0 to 9, but only includes even numbers (where i % 2 == 0)."
},
{
question: "Which of these is NOT a valid variable name?",
code: "",
options: ["_private", "2nd_variable", "variable_name", "camelCase"],
answer: 1,
explanation: "Variable names cannot start with a number. They must start with a letter or underscore."
},
{
question: "What is the purpose of the 'pass' statement?",
code: "",
options: [
"To terminate the program",
"To skip the current iteration in a loop",
"As a placeholder where syntax requires a statement",
"To pass arguments to a function"
],
answer: 2,
explanation: "The pass statement is a null operation - it does nothing. It's used when a statement is required syntactically but no action is needed."
