Multi threading and Multiprocessing are techniques used in Python to achieve parallelism and improve performance.

• Multi threading allows multiple threads to run concurrently within the same process, sharing the same memory space.

• Multiprocessing involves creating multiple processes to run tasks in parallel, each with its own memory space.

• Multi threading is more suitable for I/O-bound tasks, while multiprocessing is bette...read more

Decorators are functions that modify the behavior of other functions. Lambda functions are anonymous functions defined using the lambda keyword.

• Decorators are used to add functionality to existing functions without modifying their code.

• Lambda functions are used for creating small, anonymous functions.

• Example of decorator: @staticmethod decorator in Python.

• Example of lambda function: lambda x: x*2

Endpoints and methods for a book store API

• Endpoints: /books (GET, POST), /books/{id} (GET, PUT, DELETE), /authors (GET, POST), /authors/{id} (GET, PUT, DELETE)

• Methods: GET (retrieve data), POST (create new data), PUT (update existing data), DELETE (delete data)

• Example: GET /books - retrieve all books, POST /books - add a new book to the store

Binary search is an efficient algorithm for finding an item from a sorted list of items.

• Binary search works on sorted arrays. Example: [1, 2, 3, 4, 5].

• It divides the search interval in half. If the target is less than the middle element, search the left half.

• If the target is greater, search the right half. Example: Searching for 3 in [1, 2, 3, 4, 5] results in mid index 2.

• The time complexity is O(log n), making it much...read more

Separate odd and even numbers from an array using Python.

• Use list comprehension to filter odd and even numbers.

• Example: For array [1, 2, 3, 4], evens = [2, 4], odds = [1, 3].

• You can also use a loop to append to separate lists.

• Example: Initialize two lists, iterate through the array, and append accordingly.

Deep copy creates a new object and recursively copies the objects found in the original. Shallow copy creates a new object and references the objects found in the original.

• Deep copy creates a new object and recursively copies all nested objects, while shallow copy creates a new object and references the nested objects.

• Deep copy is used when you want to create a completely independent copy of an object, while shallow co...read more
