Today we will discuss the difference between Kotlin and Python.


Kotlin is a general-purpose, free, open-source, statically typed “pragmatic” programming language initially designed for the JVM (Java Virtual Machine) and Android that combines object-oriented and functional programming features. It is focused on interoperability, safety, clarity, and tooling support. Versions of Kotlin targeting JavaScript ES5.1 and native code (using LLVM) for several processors are in production as well.

Kotlin originated at JetBrains, the company behind IntelliJ IDEA, in 2010, and has been open source since 2012. The Kotlin team currently has more than 90 full-time members from JetBrains, and the Kotlin project on GitHub has more than 300 contributors. JetBrains uses Kotlin in many of its products including its flagship IntelliJ IDEA.



Python is a widely-used, interpreted, object-oriented, and high-level programming language with dynamic semantics, used for general-purpose programming. It was created by Guido van Rossum, and first released on February 20, 1991.

While you may know python as a large snake, the name of the Python programming language comes from an old BBC television comedy sketch series called Monty Python’s Flying Circus.

One of the amazing features of Python is the fact that it is one person’s work. Usually, new programming languages are developed and published by large companies employing lots of professionals, and due to copyright rules, it is very hard to name any of the people involved in the project. Python is an exception.

Of course, van Rossum did not develop and evolve all the Python components himself. The speed with which Python has spread around the world is a result of the continuous work of thousands (very often anonymous) programmers, testers, users (many of them aren’t IT specialists), and enthusiasts, but it must be said that the very first idea (the seed from which Python sprouted) came to one head – Guido’s.


Kotlin VS Python- Comparison


  • Statistically typed language providing OOPs and FP paradigm
  • Unicode support is present
  • Kotlin does not provide an Interpreter
  • Kotlin provides Cross-Platform application support
  • You can use HTML5 as the template language
  • Kotlin is a compiled language hence a compiler is provided
  • Kotlin Native used as a front end language
  • The operating system server is Android


  • It is one of the most popular high-level programming languages
  • Unicode Support is also present
  • Python provides an Interpreter
  • Python also provides cross-platform application support
  • You can use Django, Chameleon as a template language.
  • Python does not provide a compiler as it is an interpreted language.
  • C# used for front end language
  • The operating system server is cross-platform

Let’s see how they are different syntax:-


Let’s discuss some important features of Python Programming Language:-

  • Easy Language

Python is an easy language. It is easy to read, write, learn and understand.

  1. Python has a smooth learning curve. It is easy to learn.
  2. Python has a simple syntax and Python code is easy to understand.
  3. Since it’s easy to understand, you can easily read and understand someone else’s code.
  4. Python is also easy to write because of its simple syntax.
  • Readable

The Python language is designed to make developers' life easy. Reading a Python code is like reading an English sentence. This is one of the key reasons that make Python best for beginners.

  • Interpreted Language

Python is an interpreted language. It comes with the IDLE (Interactive Development Environment). This is an interpreter and follows the REPL structure (Read-Evaluate-Print-Loop). It executes and displays the output of one line at a time.

  • Dynamically-Typed Language

Python is not statically-typed like Java. You don’t need to declare data type while defining a variable. The interpreter determines this at runtime based on the types of the parts of the expression. This is easy for programmers but can create runtime errors.

  • Object-Oriented

Python is object-oriented but supports both functional and object-oriented programming. Everything in Python is an object.

It has OOP (Object-oriented programming) concepts like inheritance and polymorphism.


Let’s discuss some important features of Kotlin:-

  • Kotlin is Open-Source

The very first thing you should know about Kotlin is that it is an open-source programming language. But, apart from being open-source, Kotlin also provides a single-click tool using which, developers can convert existing Java code.

And if you’re an Android app developer who is new to Kotlin and interested in learning it from scratch, we recommend starting with the beginner course available on Udemy and Udacity. These courses will help you to sharpen your skills

  • Kotlin Supports Full Java Interoperability

One of the major as well as the best features of Android Kotlin is its deep interoperability with Java. This has attracted many Java developers as well as Android app developers to learn Kotlin.

it runs on JVM and also supports Java libraries as well as tools, providing full Java interoperability.

Both the languages co-exist, and this makes it easier for developers to be productive. Developers can easily compile one Android project in both languages with the help of this feature – the interoperability function.

This will allow the developer to switch the programming language instead of changing the codes. It will also save time for them to develop more Android apps.

It can show 100% interoperable. So, if you need access to a Kotlin method from a Java class or vice versa, you can do it without any extra parameters.

  • Kotlin Comes With Lazy-Loading Feature

The lazy-loading feature increases the startup time, which is very useful when using it for Android development.

In simple words, it’s the best solution for all developers who want to reduce their Android app startup time so that their apps’ content can be shown faster.

With the lazy-loading feature, Android developers can load the only resources into the main memory which are necessary. If you are looking for this feature, then Kotlin is the best choice.

For example, if you have a shopping app, the majority of users will only browse your selection, which means you could have the payment API be lazy-loaded.

  • Data Classes in Kotlin

The necessity of a class is always argued by programming language designers/makers. Typically, a data class in Java contains lots of boilerplate code which developers have to skip to find out the real use of that class.

But now in Kotlin, Android developers can write the equivalent of the same Java code simply, and with lesser code. Therefore, the data classes in Kotlin are also known to be one of the useful features.

  • Collection Filtering

We all know that when working with an API, web developers need to deal with collections quite often. But by using Kotlin’s collection filtering feature, it’s easier to tell what your resulting list should contain.
