3 Reasons Python Programming is So Popular

By

Since its introduction in the ’90s, Python has rapidly become one of the world’s most popular programming languages. Most recently, we have seen Python even surpass other languages like Java. How has a humble language like Python managed to gain so much attention? Why is Python so popular?

Some estimates claim there were over 8 million active users of Python by the end of 2018. What has created the demand for this programming language compared to Java with 7.6 million, C# with 6.7 million, and JavaScript with 11.7 million active users at the end of 2018? One way to think about using a programming language is to think about its primary use case. In the case of JavaScript, the primary function is building software for the web or the cloud. Cloud infrastructure and web development are still very common business needs. For C# and Java, these use cases are more driven to desktop application development, which has started to fall off with the rise of the mobile-first mentality of end-users.

1. The rise of analytics and Python.

With Python, the use cases are shifting to data analysis and machine learning. As Clive Humby stated back in 2006, “Data is the new oil.” The bottom line is that data science has a high value. Companies have made data analytics and data science a priority due to their abilities to maximize profits and gain better insights on business. Because of well-developed resources like the data science workhorses of Pandas and Scikit-learn, Python easily does the heavy-lifting of machine learning algorithms.

Along with ready-made tools to do the work, Python is also an incredibly readable programming language. Its syntax was explicitly designed to remove a lot of unnecessary code and emphasize making it human-readable. Python makes the development of complex programs easier to write and easier to manage, which translates directly to the bottom line of the company.

2. Why is Python so popular? One word of many: Free.

The facts that drive Python’s booming popularity: it is an open source and free to use. Developers all over the world are writing and distributing software packages in Python that small companies or individual developers can use in their projects for free. Who wouldn’t want to be able to plug into a sophisticated image segmentation library developed by Google? At no cost! Just a few years ago, similar image analysis software cost thousands of dollars and was not nearly as user-friendly.

3. It takes a village.

Python programming is easy to learn, easy to write, cheap to build with, and massive followings of programmers worldwide. It’s no wonder Python is rapidly gaining in popularity. One of the worst feelings for new developers is not understanding why their program isn’t working, but with Python, the programming and data science communities are very active. Blog posts, answer sites like StackOverflow, and groups on LinkedIn have made getting feedback and solutions to your issues easier than ever. Getting hands-on help with issues quickly, learning, and picking up better development practices are no longer a daunting task.

The best way to learn any new language is to immerse yourself. Popular programming languages like Python are no different. The more time you interact with solving real-world problems with a new language, the faster you can become fluent. There are tons of resources like YouTube videos and blog posts, but I find that there really isn’t a better-suited way to learn than hands-on teaching. You need to raise your hand and ask an instructor attuned to the Python language, programming languages, Python code, data science, python developers, artificial intelligence, programming, and machine learning, and more.

General Assembly: the bridge to machine learning.

The immense rise of use cases and companies hiring developers, allows an increase in places to learn these new skills. General Assembly has a multitude of ways to get you started on the path to learning Python and becoming a Python developer. Informal and free introduction sessions at General Assembly aim to get you running code in just a couple of hours. Part-time classes take things up a notch by giving you focused hands-on lessons twice a week, over 10 weeks — artificial intelligence will have nothing on you. For those future Python developers that are ready to take the plunge, and want a deep-dive into all things machine learning, General Assembly also offers full-time Data Science Immersive programs every quarter to learn Python code, programming, nuances of artificial intelligence — and more.

Why is Python so popular? These reasons are a very good place to start!

Getting Started with Sublime Text 3: 25 Tips, Tricks, and Shortcuts

By

Note: Sublime Text 4 has since been released and is available here.

Sublime Text 3 (ST3) is the former version of one of the most commonly used plain text editors by web developers, coders, and programmers. It is a source code editor that has a Python programming surface or API. It is able to support C++ and the Python programming language. Plus, functions can be added by any user with a plugin.

Make the most of ST3 with the 25 tips and tricks in this ultimate guide for web developers. Learn not only how to use Sublime Text 3, but also about must-have packages, useful keyboard shortcuts, and more.

1. User Preference Settings

By default, ST3 uses hard-tabs that are 4 characters long. This can result in hard-to-read code, as large tabular indents push your work to the right. I recommend all developers add this to their user settings (Sublime Text 3 => Preferences => Settings – User):

  {
    "draw_white_space": "all",
    "rulers": [80],
    "tab_size": 2,
    "translate_tabs_to_spaces": true
  }

This setting converts hard-tabs to spaces, makes indents only two characters long, puts a ruler at the 80 character mark (to remind you to keep your code concise), and adds white space markers. Here is a complete list of preference options if you wish to continue customizing your ST3 environment.

Using APIs in Full-Stack Web Development and App Creation

By

Think about your personal experiences using ride-sharing mobile apps like Lyft. You’re able to request a car to your exact geographic coordinates, right down to the street corner. This functionality is possible thanks to application programming interfaces, or APIs.

An API is a platform that allows different pieces of software, or applications, to communicate with one another. The term is used broadly in the context of programming languages, the web, operating systems, etc. For example, Apple publicly shares a number of APIs powered by iOS, its operating system for iPhones and iPads, for an app developer to use. These APIs allow applications like Facebook, Instagram and Snapchat to access a user device’s camera, microphone, and much more.

What Is an API?

APIs can fall into a number of subcategories. Many web and mobile applications, as well as devices (e.g., Amazon Echo), rely heavily on what are known as web APIs, which we’ll focus on in this guide. A web API uses the same underlying technologies as web browsers to allow different applications to communicate with one another. Web APIs allow applications to retrieve data or perform actions beyond their built-in capabilities. Typically, an application, using the internet, requests some data or action from an API. The API provides a response, and the application then adapts and displays it. The API’s code is hosted on a web server, which is essentially a computer connected to the internet. Depending on the functionality the API is providing, there may be an additional layer of security involved, such as sending a unique key.

Let’s consider a mobile weather application like Dark Sky. When you use it to check the weather for a certain zip code, the application makes a request to the API tool asking for the weather in that zip code. The API has access to the weather data and returns it as its response. Then, the application goes through the weather data and selectively displays it as, for example, the temperature in degrees Fahrenheit. The same process occurs if you check the weather in another city or at your current location.

How to Use an API

Developers can use almost any modern programming language (like JavaScript, Ruby, Python, or Java) for their own API coding. Most programming languages already come with the necessary software to interact with web APIs, but developers typically install additional packages, or code, for convenience and flexibility.

For any given programming language, there’s usually at least one popular framework — a collection of programs — that can be used to create APIs. Ruby developers, for example, use the Rails framework. Developers can also use packages to add features to their APIs, such as additional layers of security. Any additional necessary programs or packages are usually installed with that language’s package manager, e.g., Ruby’s bundler.

How Does an Internal API Work?

An internal API is one that’s used within a company or organization, although the company can choose to make portions of it accessible to the public. Users within that organization can leverage an internal API to share data and business logic (for example, the company’s rules regarding communication between a user interface and a database) across platforms — i.e., web, iOS, or an Android app. Any company with both web and smartphone apps likely has an internal API.

For example, the food-ordering service, Seamless, has web, iOS, and the Android app. All three platforms use an internal API to request that an action be performed, like placing an order for a client, as well as to request data, like the details of a user’s most recent order. This internal API allows Seamless to internally share data (restaurant information) and business logic (a customer ordering a dish) across different devices.

How Does an External API Work?

Many organizations provide external — albeit sometimes limited — APIs and documentation that allow individuals and companies outside of that organization to develop applications using its services. Depending on the external API, there may be registration, payment, or other limitations involved. For example, The New York Times provides an extensive external API that is free but requires that developers register and follow certain guidelines.

Google Maps also provides APIs that allow developers to embed maps in their websites and applications, as well as access directions and estimated travel times. Lyft, for example, uses Google Maps’ API. Other popular external APIs include Yelp’s Business APIs, which enables the user to find businesses, the OpenWeatherMap API, which retrieves weather data, and the Microsoft Azure Emotion API, which determines emotions in images.

Using external APIs allows developers to create their own mashup applications, like one that uses the Yelp Business API to find top-rated coffee shops in a neighborhood and display them on user interfaces as a map with custom icons via the Google Maps API.

HTML for Web Development: Building the Bones of Your Website

By

Hypertext Markup Language, or HTML, is a programming language used to describe the structure of information on a webpage. Together, HTML, CSS, and JavaScript make up the essential building blocks of websites worldwide, with CSS controlling a page’s appearance and JavaScript programming its functionality. You can think of the HTML document as providing the bones of a webpage, while CSS provides the skin, and JavaScript provides the brains.

A webpage can contain headings, paragraphs, images, videos, and many other types of data. Front-end developers use the HTML element to specify what kind of information each item on a webpage contains — for instance, the “p” HTML element indicates a paragraph. Developers also write HTML language code to specify how different items relate to one another in the page’s overall structure or document structure.

Every website you open in your web browser, from social networks to music services, uses HTML. A look under the hood of any website would reveal a basic HTML code page, written with an HTML structure editor, providing structure for all the page’s components, including its header element, footer element, main content, and other inline elements.

A look at the HTML code that structures General Assembly’s website.
A look at the HTML code that structures General Assembly’s website.

How HTML Works in a Webpage

The HTML file plays a couple of significant roles in a webpage. First, we use the structure created by our HTML code to reference, enhance, and manipulate elements on a web page using CSS and JavaScript. For instance, you could use HTML to mark all of the headings on a web browser page, then pick the size and color you want to apply to those headings to reflect your organization’s branding, or simply a visual design developed for the site.
Second, HTML text lets us indicate the roles of different structural elements to search engines and other services that index the content and summarize it for other users. For instance, marking the caption of an image with the “figcaption” element and enclosing the image and its caption in the “figure” meta element helps a search engine understand that these two pieces of content are related and that the caption describes the associated image.

Learning HTML at General Assembly

Whether you want to land a job as a front-end or full-stack web developer or just want to dip your toe into programming, HTML is a natural place to start. Learning HTML, along with CSS and basic JavaScript, provides you with the fundamental skills necessary to create your interactive single-page website.

In GA’s part-time courses in Front-End Web Development and HTML, CSS & Web Design, and our career-changing, full-time Web Development Immersive program, you’ll get hands-on practice coding your projects, from static personal and business websites to single-page applications like games and interactive photo galleries.

These projects give you practice using basic HTML tags and structuring pages with different components, including headers, footers, sidebars, and navigation. You’ll also code CSS and JavaScript and learn how to put all three together to build websites that implement modern standards and use best practices for front-end development.

learn to code

So, you want to learn to code? Awesome! Knowing how to code can help you level up in your current role, open new career opportunities, and empower you to make your app or website ideas come to life. But where should you start?

Although hotly contested among developers, most novice coders begin their education by learning the basics of front-end web development, or the client-facing side of web development. The front end involves what the end user sees, like the design/appearance of the web page.

In order to become a front-end developer, there are three “languages” you need to master: HTML, CSS, and JavaScript, or as I like to call them, “The Holy Trinity.”

Below, I explain the difference between these three languages, and how they work in concert to get a simple website up and running.

Mindfulness Tips for Web Developers

By

Mindfulness for Web Developers

Early in my tech career, as a web developer, I was constantly stressed out. Every time somebody needed something from me, I felt I had to drop everything and do it right then. I was overwhelmed by my growing to-do list, and doubly stressed for not doing enough quickly.

All developers face a lot of pressure. When you’re coding or creating something, clients, teammates, and managers want it fast, and they want it perfect. Plus, today’s tech teams are always expected to be on and responsive through email, phone, Slack, and beyond, which digs into time you want to spend on the work itself. These aspects of coding culture can often lead to stress, unhealthy habits, and emotional burnout, which all keep you from reaching your potential on the job. That ultimately leads to more stress, more unhealthy habits…you get the picture.
