10 best Python IDE to develop world-class software and application

An interactive programming language, Python has a simple and easily readable syntax that makes Python programs easy to understand and write. Ever since its development by Guido Van Rossum in 1991, Python is becoming popular day by day amongst programmers. From using early languages like COBOL, FORTRAN, ALGOL, C, and ADA, Python indeed reflects a major paradigm shift.

Python comes bundled with the conciseness and flexibility that the armature and professional programmers cherish so much. Name any latest technological phenomenon - Data Science Backhand Development, Artificial Intelligence, and Machine Learning – all these domains are based on Python! Due to the availability of extensive standard libraries and third-party support, it is rapidly evolving as the number one programming language amongst developers. 

If you are new to programming or want to learn how to program then it’s better if you use some kind of software that will help you develop your skills faster. There are several tools available on the internet but the most recommended tool is “Learn Python The Hard Way” because this book has been written by Zed Shaw who is also famous for his other books like Learn C++ In One Hour etc.

But to work efficiently, accurately, and systematically in Python, we would require a dedicated code editor or Python IDE - what is it? Let's explore further to discover all our answers!

What are Code Editors, Python IDEs, and IDLE?

1. Code editor

• Talking of the code editor, it's simply used to compose and edit code (code formatting). They are normally lightweight and can be extraordinary for learning how to go about coding. However, once your program starts getting bigger, the need for IDE's to test and debug the code becomes necessary.
• Contingent on the language one codes on the editor, it highlights special syntax and also gives suggestions. Some of the ingrained and famous code editors are Sublime Text, Atom, and Visual Studio Code.

2. Python IDE

A Python Integrated Development Environment (IDE) gives every one of the fundamental apparatuses required for software development with Python language.

For starters, an IDE is basically a software application that packs all the common developer tools into an exclusive user-friendly Graphical User interface. For the most part, it incorporates a source code editor to compose software programs and local build automation to develop a local build of the software-such as compiling computer source code. 

Let's quickly list some of the amazing advantages of using one of the best python IDEs:

• The Integrated Development Environment helps you deal with a huge codebase and accomplish fast deployment.
• Developers and software engineers can utilize these editors to create PC or web-based applications.
• DevOps engineers can also employ IDEs to perform continuous integration.
• It assists with task automation and improves the prolificacy and the overall proficiency of the software engineer. Python IDE's are power-packed with features such as build automation, code linting, testing, and debugging that can altogether accelerate your work. 

Well, The only downside of using IDE's is they are quite complicated to be understood and worked on. Every Python IDE or code proofreader contrasts from the other in regards to its elements, UI, etc. 

3. IDLE- An interpreter for Python

IDLE stands for Integrated Development and Learning Environment and is an IDE for Python. IDLE usually comes up with a multi-window text editor with syntax highlighting.

• It often comes bundled with Python installations and comprises Python shell and Python editor. While Python shell is an interactive interpreter, Python editor allows us to work in script mode.
• It has a practical Python shell, which makes it easier to play around with code snippets. While using Python shell we just have to type the Python code at >>> prompt and after that simply press Enter. The shell then responds with the result of the code computation. On the off chance when there is no output, then it means our code isn't working properly. We should check whether the input data is correct or not. To do this, we will use the print function which prints out any variable value.
  We can even run multiple lines of code inside Python Shell. It works like running single-line statements within a batch file.
  To exit the Python shell, we'll hit CTRL+Z key combination followed by entering.
  
• Python shell works wonders for simply writing code or for small projects, but for larger programs using a custom-built code editor or an integrated development environment (IDE) is highly recommended.

Features of a Good IDE

1. Integrated Debugger: A debugger is used to debug program errors and bugs. This feature enables developers to step through their code while executing it. In case if something goes wrong during execution, it would help them find where exactly the error occurred. For example, suppose I am trying to execute my code "print " and instead of printing 'Hello world', it throws an exception saying "SyntaxError: invalid syntax". If I don’t know what went wrong, I might try stepping into the code and see how far it got before throwing up an error. With a debugger, I could easily figure out why the code didn't work. In most IDEs, the debugger escalates through your code and applies breakpoints for executing the code partially. 
2. Highlighting of syntaxes: Having the option to spot keywords, variables, and symbols in your code makes perusing and understanding code a lot simpler. 
3. Automated formatting of Code: A rather intriguing element, the code indents itself as you use functions, and loops while you compose your program.
4. Automatically save and reload source code: A developer's schedule is tightly packed indeed, and hence an IDE should save your work and resume everything later - in a similar state it was in when you left to save you time later on.
5. Execution from within the environment: It ought to have an inherent compiler to execute your code, if not, then it's merely a code text editor.

This article has thoroughly listed down and explained some of the most significant and best python IDEs that are highly recommended by the Python Community.
