The code will print 'o wo', which is the substring of 'Hello world' starting from index 4 up to index 7.
The slicing operation str[4:8] extracts characters from index 4 to index 7 (exclusive) from the string 'Hello world'.
The index 4 corresponds to the character 'o' and index 7 corresponds to the character 'd'.
Therefore, the output of print(str[4:8]) will be 'o wo'.

Lists are mutable in Python.
Lists can be modified after creation, allowing for addition, removal, and modification of elements.
Tuples, strings, integers, and floats are immutable in Python.
Example: list_example = [1, 2, 3]; list_example[1] = 5 # modifies the list element at index 1 to 5.
CSS properties control the visual presentation of elements on a webpage.
color: sets the color of text
font-size: determines the size of text

border: defines the border around an element
margin: sets the margin outside an element

Broadcast joins optimize performance by distributing smaller datasets to all nodes for efficient data processing in big data frameworks.
Used when one dataset is significantly smaller than the other, e.g., joining a small lookup table with a large fact table.
In Spark, the smaller dataset is broadcasted to all worker nodes, reducing data shuffling and improving join performance.
Example: Joining a user profile table ...
Web application performance can be handled by optimizing code, caching, load balancing, and monitoring.
Optimize code by reducing database queries, using efficient algorithms, and minimizing HTTP requests.
Implement caching to reduce server load and improve response time.
Use load balancing to distribute traffic across multiple servers.
Monitor performance using tools like New Relic or Google Analytics to identify bot...
Web application flow involves client-server communication, request processing, and response generation.
Client sends a request to the server
Server processes the request and generates a response
Response is sent back to the client
Client renders the response in the browser
This flow continues until the user interacts with the application
OOPs (Object-Oriented Programming) is a programming paradigm based on objects and classes, promoting code reusability and modularity.
Encapsulation: Bundling data and methods that operate on the data within one unit (e.g., a class).
Inheritance: Mechanism to create a new class using properties of an existing class (e.g., a 'Dog' class inheriting from an 'Animal' class).
Polymorphism: Ability to present the same inter...
Interceptors in Angular are used to intercept HTTP requests and responses.
Interceptors can be used to modify requests before they are sent and responses before they are received.
They can be used for tasks like adding headers, logging, error handling, etc.
Example: Creating an interceptor to add a token to every outgoing request for authentication.
Program to print decreasing number of asterisks in each line
Create a loop to iterate from n to 1

Lists are mutable in Python.
Lists can be modified after creation, allowing for addition, removal, and modification of elements.
Tuples, strings, integers, and floats are immutable in Python.
Example: list_example = [1, 2, 3]; list_example[1] = 5 # modifies the list element at index 1 to 5.
- Q2. Str="Hello world" print(str[4:8] )
- Ans.
The code will print 'o wo', which is the substring of 'Hello world' starting from index 4 up to index 7.
The slicing operation str[4:8] extracts characters from index 4 to index 7 (exclusive) from the string 'Hello world'.
The index 4 corresponds to the character 'o' and index 7 corresponds to the character 'd'.
Therefore, the output of print(str[4:8]) will be 'o wo'.
