Creating a CSV File in Python: Need Guidance and Code Example

Issue with Asynchronous Data Fetching in Full Stack JavaScript Application
I'm facing an issue while developing a full-stack JavaScript application that involves asynchronous data fetching. I'm using technologies like Node.js for the backend and React for the front end. The problem arises when I try to fetch data from the backend API asynchronously and update the UI using React components. The data seems to be returning from the API correctly, but it's not rendering as expected in the React components. I have been trying... -
How Can I Optimize My Python Flask API for Better Performance?
I'm presently working on a backend development project to build a RESTful API using Python and Flask. Although I've had assistance with this site (Illegal link removed), I've seen a drop in performance as the amount of API queries rises. Especially during times of high usage, the response times are slower than I would want them to be.
Here's a simplified version of my Flask API code:

ROLLBACK in SQL in a Spring Transaction
I need to execute a SQL Server stored procedure from Java/Spring, and the SP has a try/catch block that logs errors to a table. The logging is required because the SP is also called manually or from a database task, however in my case, it creates an issue because the call from Spring is transactional (see https://stackoverflow.com/a/15984867/302151).
Is a ROLLBACK in the catch block sufficient to address my problem, and if so, is it... -
Final Keyword In Java

Now let's see if I can code:Code:public class bytes { public static void main(final String... args) { System.out.println("Hi"); } }
...Code:public class bytes { public -

Why is Java's String class designated final?
I was curious why the class java.lang.Strin g is defined as final in Java when I first learned about it. I couldn't find an answer back then, but check out this post: How to Create a Java String Class Replica. It reminded me of my question.
Sure, String gives all the functionality I've ever required, and I've never considered any action that would necessitate an extension of class String, but you never know what someone could demand!... -

Hey, thanks for the clarification! It truly cleared my doubt. Also, I need assistance with some coding here. I intended to use a dictionary to construct the switch case pattern in Python, as this tutorial suggested, but here's the problem:
...Code:# Type can be either create or update or .. message = { 'create':msg(some_data), 'update':msg(other_data) # can have more } -
Python string find() examples
I'm looking for examples, but I'm not finding any.

Web Api for Self-Hosting and Web-Hosting
Is there a recommended practice for supporting self-hosting and web-hosting simultaneously?
