What is a variable in programming?
A special type of function
A container for storing data values
A loop structure for iteration
A template for creating objects
A variable is used to store data values in memory so they can be referenced and manipulated. Variables act as named containers that hold different types of data like numbers or text. They are fundamental to programming because they enable dynamic and flexible code. .
What is the purpose of a conditional statement in programming?
To execute code based on a specified condition
To store data values temporarily
To repeat a block of code multiple times
To define reusable blocks of code
Conditional statements allow the program to take different paths based on whether a condition is true or false. They enable decision-making in code and control the flow of execution. Without them, programs would be unable to respond dynamically to different inputs or states. .
Which keyword is used to define a function in Python?
define
func
function
def
In Python, the def keyword is used to introduce a function definition. It is followed by the function name and parentheses containing any parameters. Functions defined with def can be called elsewhere in the code to perform specific tasks. .
Which of these is a Python data type used to represent whole numbers?
Integer
Float
String
Boolean
The integer data type represents whole numbers without a fractional component. In Python, integers can be positive, negative, or zero. They are distinct from floats, which represent numbers with decimals. .
Which loop structure is typically used to iterate over the elements of a sequence a fixed number of times?
def statement
for loop
if statement
while loop
A for loop is used to iterate over the elements of a sequence (like a list or string) or a range of numbers. It runs the loop body once for each element in the iterable. While loops repeat based on a condition rather than iterating a fixed sequence. .
How do you add a comment in Python?
By prefixing the line with #
By enclosing text in /* */
By prefixing the line with //
By enclosing text in
In Python, comments are marked by the # symbol and extend to the end of the line. Comments are ignored by the interpreter and used to explain code for human readers. Other languages use different comment syntax, such as // or /* */. .
Which function is used to display output to the screen in Python?
echo()
print()
write()
display()
The print() function in Python outputs text or variables to the console. It's commonly used for debugging and user communication. Unlike some other languages, Python does not use a separate command for console output. .
Which of the following Python data types is immutable?
List
Tuple
Dictionary
Set
Tuples in Python are immutable, meaning once created their elements cannot be changed. Lists, dictionaries, and sets are mutable, so their contents can be modified. Immutable structures can be safer for data integrity. .
In object-oriented programming, what is an object?
A standalone function
A collection of modules
A blueprint for creating classes
An instance of a class
An object is a concrete instance of a class that contains both data (attributes) and behavior (methods). Classes act as blueprints defining the structure and behavior for their objects. Objects are central to encapsulation and inheritance in OOP. .
What differentiates a class from an instance in OOP?
A class is a blueprint, an instance is a created object
An instance defines methods, a class stores data
A class is mutable, an instance is not
A class runs at runtime, an instance runs at compile time
A class defines the structure and behavior (attributes and methods), while an instance (object) is a specific realization of that blueprint in memory. Multiple instances can share the same class but hold different data values. This distinction supports code reuse and modularity. .
What is encapsulation in object-oriented programming?
Polymorphic behavior at runtime
Breaking code into multiple files
Inheritance of properties from a parent class
Bundling data and methods within a class
Encapsulation refers to the bundling of attributes (data) and methods (functions) that operate on the data into a single unit, the class. It also involves restricting direct access to some of an object's components for data hiding. This promotes modularity and maintainability. .
Which syntax correctly creates a list comprehension to square numbers 1 through 5?
[x^2 in range(1, 6)]
for x in range(1,6): x**2
list(x**2 for x in 1..5)
[x**2 for x in range(1, 6)]
The list comprehension [x**2 for x in range(1, 6)] iterates x from 1 to 5 and computes its square. The result is a new list containing each squared value. List comprehensions are concise and more efficient than manual loops. .
What happens when you assign two identical keys in a Python dictionary?
The dictionary becomes immutable
An error is raised
The latter value overrides the former
Both entries are stored separately
When duplicate keys are assigned in a Python dictionary, the most recent assignment replaces the previous value for that key. Dictionaries maintain unique keys, so earlier data under the same key is lost. No error is thrown by default. .
What is method overriding in object-oriented programming?
A function calls itself recursively
A class defines two methods with the same name
A subclass provides its own implementation of a parent method
A class repeats inherited methods without change
Method overriding occurs when a subclass defines a method with the same name as one in its superclass, replacing the inherited behavior with a new implementation. This enables specialized behavior in derived classes. Overriding supports polymorphism. .
In Python classes, which method serves as the constructor?
__init__
__construct__
__start__
__new__
The __init__ method in Python initializes a newly created object and acts as its constructor. When you instantiate a class, __init__ is automatically called to set up initial state. __new__ handles low-level object creation. .
Which SQL clause filters rows based on a specified condition?
HAVING
GROUP BY
WHERE
ORDER BY
The WHERE clause is used in SQL to filter records before any grouping or ordering. It specifies which rows to include based on the given condition. HAVING is applied after GROUP BY, while ORDER BY sorts the result. .
What is the primary purpose of a primary key in a relational database?
To establish a link to another table
To encrypt sensitive data
To improve query performance
To uniquely identify each record in a table
A primary key uniquely identifies each row in a database table, ensuring no two records share the same key value. It enforces entity integrity and improves indexing for lookups. Foreign keys reference primary keys in related tables. .
Which HTTP method appends data to the URL in a request?
GET
DELETE
PUT
POST
GET requests append data as query parameters in the URL, visible after the ? character. POST sends data in the request body. GET is typically used for retrieving resources, while POST is for creating or updating. .
In CSS, which property controls the space between an element's content and its border?
margin
padding
gap
border-width
The padding property sets the space between an element's content and its border. Margin controls space outside the border, while border-width defines the thickness of the border itself. Proper use of padding and margin is key to layout. .
What role does JavaScript primarily play in web development?
Configuring web servers
Styling page layout
Defining HTML structure
Client-side scripting for interactivity
JavaScript is a client-side scripting language that adds interactivity and dynamic behavior to web pages. It manipulates the Document Object Model (DOM), handles events, and communicates asynchronously. HTML structures the page, and CSS styles it. .
Which SQL JOIN returns only the rows that have matching values in both tables?
RIGHT JOIN
INNER JOIN
FULL OUTER JOIN
LEFT JOIN
An INNER JOIN returns rows when there is a match in both tables based on the specified condition. LEFT JOIN returns all rows from the left table and matched rows from the right, while RIGHT JOIN does the opposite. FULL OUTER JOIN includes all matched and unmatched rows. .
What does HTTP status code 404 indicate?
Resource not found
Unauthorized access
Internal server error
Bad request
A 404 status code means the requested resource could not be found on the server. It indicates that the server itself is reachable but the specific page or file does not exist. This is a client-side error. .
What type of vulnerability is Cross-Site Scripting (XSS)?
Injection of malicious scripts into trusted websites
Intercepting encrypted network traffic
Exploiting buffer overflows on a server
Forcing user logout via CSRF token
Cross-Site Scripting (XSS) vulnerabilities occur when attackers inject malicious scripts into webpages viewed by other users. The injected code runs in the victim's browser context, enabling data theft or session hijacking. Preventing XSS involves input validation and output encoding. .
Which security principle requires granting only the permissions necessary for a task?
Principle of least privilege
Security through obscurity
Separation of duties
Defense in depth
The principle of least privilege dictates that users or processes should have only the minimum access rights needed to perform their tasks. This reduces the attack surface and limits potential damage from compromised accounts. It is fundamental in secure system design. .
