Posted on Mar 7                  In today's data-driven world, being able to extract insights from data is a valuable skill. In this article, we'll explore how to perform basic data analysis using Python and SQL. We'll connect to a SQLite database, execute SQL queries, and visualize the results using Python libraries. 📊The database contains information about sales transactions made by a company. Here's what each field represents:The provided schema simulates a basic sales database, commonly used in retail or e-commerce settings. Each transaction (identified by TransactionID) involves the sale of one or more products. For each product sold, the database records the ProductID, ProductName, Quantity sold, PricePerUnit, and the date of the transaction (SalesDate).Purpose:This database schema and the accompanying data were created for the purpose of practicing database management and performing data analysis tasks,it is not real-world data.But it provides a simplified representation of sales transactions, making it suitable for learning SQL queries, data manipulation, and analysis.Note:It's important to note that in a real-world scenario, databases and data structures may be more complex, and additional considerations such as data integrity, normalization, and indexing would be taken into account. However, for learning and practice purposes, this schema serves as a good starting point.First, let's ensure we have the necessary tools installed. We'll need Python, SQLite, and the matplotlib library for data visualization. 💻We'll start by creating a SQLite database and populating it with some sample data. We'll then connect to this database using Python's sqlite3 library. 🔌We'll define a schema for our database containing information about sales transactions. The schema includes fields such as TransactionID, ProductID, ProductName, Quantity, PricePerUnit, and SalesDate. 💼Now that our database is set up, let's perform some basic data analysis tasks using SQL queries. 📊We'll calculate the total sales revenue for each product by multiplying the Quantity with PricePerUnit and summing it up. 💰We can visualize the results using Python libraries such as matplotlib. 📊We'll find the top 3 best-selling products based on the total quantity sold. 🏆outputWe'll calculate the average price per unit for all products. 📈outputIn this article, we've demonstrated how to connect to a SQLite database using Python, execute SQL queries, and perform basic data analysis tasks. By leveraging Python libraries such as sqlite3 and matplotlib, we can efficiently analyze data and gain valuable insights. 🚀  Templates let you quickly answer FAQs or store snippets for re-use.

New Here, What to Do?

Posted on Mar 6                  I want share #we_coded thoughts as an opportunity to say - use your voice in various ways, especially to support each other on the dev journey.I started my blog in 2016 and initially I felt embarrassed to admit it was mine. I didn't sign it and wouldn't confess it was me writing, even though my closest friends knew I was writing about programming. It wasn't that I was ashamed of writing about code, but rather that I felt incompetent because I was still studying Faculty of Computing Science and working as a Junior to be "allowed" to speak about programming. I knew too little.I was too afraid to use my voice openly.Even when, I was presenting at Frontownia a front-end meeting (on "How to build landing pages that convert like crazy") and  mentor at PyCode Workshops 2015, and later Django Girls and so on..., but I always felt it was not enough. There were many moments in my coding career when I just wanted to cry because I didn't know how to move forward or couldn't fix an issue.But I survived. And it have been 9 years!Today, I work at a great company and spare my time to the foundation CODE:ME, mentoring, teaching programming. I have founded a local women's tech community, organize groups & meetings - Nerds Coding Gang, and maintain a blog (flynerd.pl with free python course in polish). I offer support to everyone to prevent those unnecessary tears over 'it's just a machine' and 'it's just code.Last year, I received the Women Who Code, Technologies to Watch Award. Did I deserve it? I don't know, but it definitely made me think and act, realizing that someone is watching and I can be an inspiration.Here are some tips if you're just starting your career as a developer, regardless of your identity.Ok, I love what I'm doing, and at times, I hate it. It's a love-hate relationship. If you imagine programmers as people from whose fingertips only clean and functional code flows, then… you have a vivid imagination 😉Programming is actually a tedious task, and the number of lines of code produced is often inversely proportional to the time spent thinking about the complexity of a given problem and finding a solution. Sometimes the most efficient code is just two lines long, and sometimes a task titled "simple UI changes" turns out to be an 8-day backend task, whose visible end result is displaying an additional column in a table. And this is not hyperbole, but a real-life example.There are days when reality hits you in the face, and you have to deal with it, feeling frustrated that technology isn't responding to you.Once (in was 2013) I wrote:"While searching for a solution to a given task or algorithm, I often feel like a homing pigeon searching for its route...I forgot to add:...a blind homing pigeon that suffers from a fear of heights and Alzheimer's."Everyone has started at some point and felt this way.Once, I thought programming was a calm, stress-free, well-paid job. Today, I know that only the last part is true 😉 Maybe it's also a matter of approach, but I can't stand leaving work with my code not working. It has to be 1:0 for me, end of story. (But lastly, I'm working at my stress-free attitude - wish me luck)If it doesn't work out – tough, QA will joyfully hit the "rejected" button. You have to learn from mistakes. Over the last 8 years, I've gained a vast amount of technical skills, but also discovered what “teamwork” really means, and learned quite a bit about myself. Example, I'm not naturally a 'team player.' I prefer to concentrate on tasks within my own bubble, but I'm able to work through it. At the same time, I'm a natural leader with the ability to convince others of my ideas, yet I have also learned how to listen more. I have become the coworker I would prefer to meet, finding ways to effectively collaborate with my team.Learning when to ask for help is an important part of being a developer. When I was a Junior, I didn't want to be the person who constantly asks silly questions. On the other hand, I didn't want to spend hours on something, having a nervous breakdown, when the help of a more experienced developer could simply save a lot of time and stress.When I started my internship, I was told to spend 30 minutes searching, and if I didn't know what and how – to ask and not waste time. The worse situation is when you don't even know what to ask about.Find a mentor and ask questions, there's nothing wrong in it.You should start from the beginning. Every child in preschool knows this. Unfortunately, it's not always possible.When I started working, I joined a company that operates in the market. We develop code that has been evolving for several years. New features are added, bugs are fixed, old code needs refactoring, and some of it we say goodbye to forever. The domain knowledge or project-specific knowledge is vast, and acquiring this knowledge always takes time.To this day, I use the rubber duck method.Really! Although I thought that the whole idea of talking to an object was a joke, I myself experienced that vocalizing my thoughts aloud suggests a solution.It also happens that by introducing another developer to the task, we are forced to recount everything we already know. It's possible that at that moment, the solution will present itself.Writing down steps or creating flowcharts of how I want to solve a problem can help. This is also a good basis for discussion with another developer when something doesn't work out. Then, it could turns out that I was missing some information, which I would never have figured out on my own, or it would have taken me a tremendous amount of time, and all I needed to do was ask.Write down interesting statements or intriguing snippets of code. I collect all tips, pro-tips, and useful information in my notes. They are enriching, but selection is necessary - there are so many interesting topics that there's no time to dedicate to each one of them.I write it down too little, but partly that's what my blog and dev.to are for.When I was starting out, initiatives for women in tech were just beginning to gain momentum. Offensive jokes were quite commonplace ("Two girls are walking, one is ugly and the other is also from IT"), and women constituted only 10% of Computer Science programs (now slowly growing). We have achieved significant social progress since then, making IT much more diverse & inclusive space. But it would not have been possible without efforts to create a more inclusive environment, driven by all allies. Let's keep doing this, keep creating an open and empathetic environment.Templates let you quickly answer FAQs or store snippets for re-use.        Are you sure you want to hide this comment?

Empowering Growth: Lessons Learned After 9 Years of Coding

We’re so glad you’re here. You can expect all the best TNS content to arriveMonday through Friday to keep you on top of the news and at the top of your game.Check your inbox for a confirmation email where you can adjust your preferencesand even join additional groups.Follow TNS on your favorite social media networks.Become a TNS follower on LinkedIn.Check out the latest featured and trending stories while you wait for yourfirst TNS newsletter.Slack has launched a new free developer web portal to provide access to tools for building Slack apps, the ability to create sandboxes for testing beta apps and features, and a showcase of best practices and features.Rukmini Reddy, Slack’s SVP of Engineering, who leads the company’s first-party developer experience, said Slack’s goal with the new portal is to meet developers where they are.That means Slack is enabling developers to build Slack apps in a way that integrates into their existing software development lifecycle. As such, Slack has added support for scripting with the Slack CLI, including integrating the Slack CLI to your CI/CD pipeline. This will help automate testing and deploying apps according to an organization’s best practices. In addition, Slack has created a guide for building the CLI into your DevOps pipeline.Moreover, Reddy said she has received several requests for enhancements to Slack’s Bolt development framework. And with the new Slack developer portal. developers can now build new Bolt for Python and Bolt for JavaScript apps that allow for the creation of custom functions that can be deployed anywhere a Bolt app can.This allows developers to write functions in JavaScript or Python that are hosted in their own data center and available in Workflow Builder, which is Slack’s visual tool for automating routine processes. These are available for new Bolt for Python and Bolt for JS applications today in beta, with a full release this spring with the ability to add functions to existing Bolt apps, including Bolt for Java.Slack functions are Slack-native actions, like creating a channel or sending a message. Custom functions are how developers define custom workflow steps. Slack launched functions last year as part of a set of new features. The first version of functions made apps more composable, easier to deploy and integrated right into Workflow Builder. Now developers can write functions in more languages and host them wherever they choose, Reddy said.In addition to the Bolt enhancements, developers also requested more lifecycle integration, Reddy said. “We also are integrating our Slack CLI. We are providing the ability for you to integrate the Slack CLI into your CI/CD pipeline,” Reddy told The New Stack. “So this is a new home for Slack developers, with a custom functions beta and better integration into your software lifecycle.”Indeed, the new features provided in the portal not only include custom functions that are composable and modular and next-gen workflows to distribute custom code but also sandboxes to test the full enterprise experience.Developers face challenges with integrating AI into workflows, managing vast amounts of siloed data, and keeping up with trends, Reddy said. They need early access to testing environments with privacy and security.The developer portal introduces “sandboxes” for developers to create full Enterprise Grid instances for testing apps without interfering with production workspaces. Developers can provision up to 10 sandboxes with full admin control and access to all of Slack’s paid features.Sandboxes are useful for both developers and admins looking to test new features or apps in development, providing a safe environment.Meanwhile, Slack’s new developer portal offers a new newsletter that points out new features developers should take advantage of, as well as apps and best practices to follow. Another new element of the portal is Events, which shows developers where they can meet the Slack team and other developers around the world, in virtual meetups or in person.“The new developer portal provides a one-stop-shop to access tools, spin up sandboxes, and open up new possibilities for developers on Slack’s open and secure platform,” Reddy explained.Community created roadmaps, articles, resources and journeys fordevelopers to help you choose your path and grow in your career.
