Python Application

Python Applications

Python supports cross-platform operating systems which makes building applications with it all the more convenient. Some of the globally known applications such as youtube, BitTorrent, DropBox, etc. use Python to achieve their functionality.

1. Web Development

Python can be used to make web-application at a rapid rate. Why is that? It is because of the frameworks Python uses to create these applications. There is common-backend logic that goes into making these frameworks and a number of libraries that can help integrate protocols such as HTTPS, FTP, SSL etc. and even help in the processing of JSON, XML, E-Mail and so much more.

Some of the most well-known frameworks are Django, Flask, Pyramid. Why use a framework? The security, scalability, convenience that they provide is unparalleled compared to starting the development of a website from scratch.

2. Game Development

Python is also used in the development of interactive games. There are libraries such as PySoy which is a 3D game engine supporting Python 3, PyGame which provides functionality and a library for game development. Games such as Civilization-IV, Disney’s Toontown Online, Vega Strike etc. have been built using Python.

3. Machine Learning and Artificial Intelligence

Machine Learning and Artificial Intelligence are the talks of the town as they yield the most promising careers for the future. We make the computer learn based on past experiences through the data stored or better yet, create algorithms which makes the computer learn by itself. The programming language that mostly everyone chooses? It’s Python. Why? Support for these domains with the libraries that exist already such as Pandas, Scikit-Learn, NumPy and so many more.

Learn the algorithm, use the library and you have your solution to the problem. It is that simple. But if you want to go the hardcore way, you can design your own code which yields a better solution, which still is much easier compared to other languages.

4. Data Science and Data Visualization

Data is money if you know how to extract relevant information which can help you take calculated risks and increase profits. You study the data you have, perform operations and extract the information required. Libraries such as Pandas, NumPy help you in extracting information.

You can even visualize the data libraries such as Matplotlib, Seaborn, which are helpful in plotting graphs and much more. This is what Python offers you to become a Data Scientist.

5. Desktop GUI

Python can be used to program desktop applications. It provides the Tkinter library that can be used to develop user interfaces. There are some other useful toolkits such as the wxWidgets, Kivy, PYQT that can be used to create applications on several platforms.

You can start out with creating simple applications such as Calculators, To-Do apps and go ahead and create much more complicated applications.

6. Web Scraping Applications

Python can be used to pull a large amount of data from websites which can then be helpful in various real-world processes such as price comparison, job listings, research and development and much more. Python has a library called BeautifulSoup which can be used to pull such data and be used accordingly. Here’s a full-fledged guide to learn Web scraping with Python.

7. Business Applications

Business Applications are different than our normal applications covering domains such as e-commerce, ERP and many more. They require applications which are scalable, extensible and easily readable and Python provides us with all these features. Platforms such as Tryton can be used to develop such business applications.

                                                 8. Audio and Video Applications

Python can be used to develop applications that can multi-task and also output media. Video and audio applications such as TimPlayer, Cplay have been developed using Python libraries and they provide better stability and performance compared to other media players.

9. CAD Applications

Computer-Aided Designing is a very complicated application to make as many things have to be taken care of. Objects and their representation, functions are just the tip of the iceberg when it comes to something like this. Python makes this simple too and the most well-known application for CAD is Fandango.Computer-Aided Designing is a very complicated application to make as many things have to be taken care of.

Advantages and Disadvantages of HTML Language?

Advantages:

• HTML is widely used.
• Every browser supports HTML Language.
• Easy to learn and use.
• Do not need to purchase any extra software because it is by default in every window.

Disadvantages:

• HTML can create only static and plain pages so if we need dynamic pages then HTML is not useful.
• I need to write a lot of code for making a simple webpage.
• Security features are not good at HTML.
• If we need to write long code for making a webpage then it produces some complexity.

Advantage And Disadvantage of JavaScript?

Advantages of JavaScript

Firstly, we will discuss the benefits or advantages of using JavaScript –

1. Speed

Since JavaScript is an ‘interpreted’ language, it reduces the time required by other programming languages like Java for compilation. JavaScript is also a client-side script, speeding up the execution of the program as it saves the time required to connect to the server.

2. Simplicity

JavaScript is easy to understand and learn. The structure is simple for the users as well as the developers. It is also very feasible to implement, saving developers a lot of money for developing dynamic content for the web.

3. Popularity

Since all modern browsers support JavaScript, it is seen almost everywhere. All the famous companies use JavaScript as a tool including Google, Amazon, PayPal, etc.

4. Interoperability

JavaScript works perfect with other programming languages and therefore numerous developers prefer it in developing many applications. We can embed it into any webpage or inside the script of another programming language.

5. Server Load

As JavaScript operates on the client-side, data validation is possible on the browser itself rather than sending it off to the server. In case of any discrepancy, the whole website needs not to be reloaded. The browser updates only the selected segment of the page.

6. Rich Interfaces

JavaScript provides various interfaces to developers for creating catchy webpages. Drag and drop components or sliders may give a rich interface to the webpages. This leads to improved user-interactivity on the webpage.

7. Extended Functionality

Third-party add-ons like Greasemonkey (a Mozilla Firefox extension) allow the developers to add snippets of predefined code in their code to save time and money. These add-ons help the developers build JavaScript applications a lot faster and with much more ease than other programming languages.

8. Versatility

JavaScript is now capable of front-end as well as back-end development. Back-end development uses NodeJS while many libraries help in front-end development like AngularJS, ReactJS, etc.

9. Less Overhead

JavaScript improves the performance of websites and web applications by reducing the code length. The codes contain less overhead with the use of various built-in functions for loops, DOM access, etc.

 

Disadvantages of JavaScript

Now after discussing the advantages of using JavaScript, its time to have a look at some disadvantages of using JavaScript which we have briefly discussed below –

1. Client-side Security

Since the JavaScript code is viewable to the user, others may use it for malicious purposes. These practices may include using the source code without authentication. Also, it is very easy to place some code into the site that compromises the security of data over the website.

2. Browser Support

The browser interprets JavaScript differently in different browsers. Thus, the code must be run on various platforms before publishing. The older browsers don’t support some new functions and we need to check them as well.

3. Lack of Debugging Facility

Though some HTML editors support debugging, it is not as efficient as other editors like C/C++ editors. Also, as the browser doesn’t show any error, it is difficult for the developer to detect the problem.

4. Single Inheritance

JavaScript only supports single inheritance and not multiple inheritance. Some programs may require this object-oriented language characteristic.

5. Sluggish Bitwise Function

JavaScript stores a number as a 64-bit floating-point number and operators operate on 32-bit bitwise operands. Thus, JavaScript converts the number to 32-bits signed integers, operates on them and converts them back to 64-bits JavaScript numbers. This continuous conversion takes more time in conversion of number to an integer. This increases the time needed to run the script and reduces its speed.

6. Rendering Stopped

A single code error can stop the rendering of the entire JavaScript code on the website. To the user, it looks as if JavaScript was not present. However, the browsers are extremely tolerant of these errors.

What Is JavaScript?

JavaScript is the Programming Language for the Web.

JavaScript can update and change both HTML and CSS.

JavaScript can calculate, manipulate and validate data.

JavaScript is a dynamic computer programming language.

It is lightweight and most commonly used as a part of web pages, whose implementations allow client-side script to interact with the user and make dynamic pages.

It is an interpreted programming language with object-oriented capabilities

JavaScript was first known as LiveScript, but Netscape changed its name to JavaScript, possibly because of the excitement being generated by Java. 

JavaScript made its first appearance in Netscape 2.0 in 1995 with the name LiveScript. 

The general-purpose core of the language has been embedded in Netscape, Internet Explorer, and other web browsers.

Client-Side JavaScript

Client-side JavaScript is the most common form of the language. The script should be included in or referenced by an HTML document for the code to be interpreted by the browser.

It means that a web page need not be a static HTML, but can include programs that interact with the user, control the browser, and dynamically create HTML content.

The JavaScript client-side mechanism provides many advantages over traditional CGI server-side scripts. For example, you might use JavaScript to check if the user has entered a valid e-mail address in a form field.

The JavaScript code is executed when the user submits the form, and only if all the entries are valid, they would be submitted to the Web Server.

JavaScript can be used to trap user-initiated events such as button clicks, link navigation, and other actions that the user initiates explicitly or implicitly.

JavaScript Development Tools

One of major strengths of JavaScript is that it does not require expensive development tools. You can start with a simple text editor such as Notepad. Since it is an interpreted language inside the context of a web browser, you don't even need to buy a compiler.

To make our life simpler, various vendors have come up with very nice JavaScript editing tools. Some of them are listed here −

• Microsoft FrontPage − Microsoft has developed a popular HTML editor called FrontPage. FrontPage also provides web developers with a number of JavaScript tools to assist in the creation of interactive websites.
• Macromedia Dreamweaver MX − Macromedia Dreamweaver MX is a very popular HTML and JavaScript editor in the professional web development crowd. It provides several handy prebuilt JavaScript components, integrates well with databases, and conforms to new standards such as XHTML and XML.
• Macromedia HomeSite 5 − HomeSite 5 is a well-liked HTML and JavaScript editor from Macromedia that can be used to manage personal websites effectively.
