Julia vs Python: What should you Learn? [Expert Advice]

What is Python?

Python is a popular programming language. It was first launched in 1991 and is a high-level, interpreted, general-purpose, multi-paradigm language. It’s loaded with resources for creating apps and websites, as well as libraries for working with AI and ML (ML). Python is the language of choice if you want to get into programming.

Python’s popularity among programmers is due to the language’s robustness, flexibility, and easily learnable syntax. Seventy percent of developers claim they use Python to create high-performance AI and ML algorithms for NLP and sentiment analysis. Data scientists typically work in Python or R.

Python’s flexibility is due in great part to the extensive ecosystem of third-party libraries built by the language’s prolific developer community. Several of these modules are essential to Python’s ability to do the necessary scientific and mathematical tasks for Data Science. NumPy, TensorFlow, PyTorch, Pandas, and Maplotlib are among the most widely used.

Python’s ability to interface with SQL databases and support for common data formats like CSV and JSON files are other reasons to use it.

Python’s Unique Features

  • It’s a high-level programming language that’s easy for developers to pick up and utilize.
  • This language has no barriers to entry and may be downloaded from its official website at no cost.
  • The language has built-in support for a number of important object-oriented concepts, including classes, polymorphism, encapsulation, and more.
  • Since Python is an extensible language, its code can be written in C or C++ and compiled to run on the platform of your choice.
  • It’s not a compiled language; rather, it’s read and understood by humans. The lines are executed one at a time, which facilitates code debugging.
  • Since this is a dynamically typed language, the data type of variables is determined at runtime, and there is no need to declare variables before using them.
  • Python comes with a ton of libraries that may be imported and utilized to cut down on tedious coding tasks. This eliminates the necessity for coders to recreate the same code twice.

What is Julia?

With its first stable release in 2018, Julia is a relatively new programming language that was developed in 2012 to satisfy the needs of the Data Science and Machine Learning fields for a faster, more mathematically focused language.

Julia is a programming language that utilizes the Concurrent, Parallel, and Distributed Computing advantages of modern hardware while combining the best elements of previous programming languages.

Julia, like Python in syntax, is a dynamic, high-level, high-performance programming language made primarily for technical computing. As a result of the central role played by linear algebra in this language, it is widely used for mathematical tasks including Machine Learning, Data Science, data mining, and numerical analysis.

For handling complex data models, Julia’s simplicity, outstanding efficiency, and speed are major selling points. However, scientists are opposed to the idea of translating the formulaic language of science into code. Since Julia is Greek-letter-friendly, mathematical formulae need not be translated into code but can be used directly in the code.

Julia’s Unique Features

  • Julia has a Read Eval Print Loop (REPL) that can be used to add commands at the command prompt.
  • As a JIT-compiled language, Julia is compiled only when it’s needed.
  • The LLVM collection framework is responsible for Julia’s lightning-fast execution.
  • The syntax in Julia is really elementary.
  • It’s easy to use, and it can import and use libraries written in other languages like Fortran, C, and Python.
  • Static and dynamic typing are both available in Julia. Variables can be declared before they are used, or you can write a function that works with them implicitly.
  • The debugger allows developers to insert breakpoints and examine their outcomes.
  • Thanks to Julia’s meta-programming capabilities, Julia programs can create other Julia programs.
  • Because its syntax is so close to that of mathematical equations, Julia is particularly well-suited to the needs of those who are developing applications with a heavy mathematical component.

Now, let’s get to business – we wil finally decide what’s the best – Julia OR Python…

Julia VS Python

You now have a firm grasp on the nature of these languages. Let’s take a look at some of the similarities and differences between Julia and Python so you can decide which one is right for you. The Julia and Python programming languages are compared below. Check out the contrasts to see which language is best for you.


It’s safe to say that Python is now the most widely used programming language. Over its 30 years of operation, it has collected one of the largest developer communities of any language, with experts ready to assist with any problem.

Although Julia’s fan base has been steadily growing, the writers continue to provide the vast majority of the community’s support. There is a growing community of Julia users and blogs dedicated to sharing their knowledge of the language and its various applications. At the time of writing, Python was at the top of the Tiobe Measure, the most well-known monthly popularity index of programming languages, and Julia was at the 36th spot.

As Julia’s use grows beyond the realm of data science, its popularity is likely to rise. The language just added support for web development frameworks, which will increase its utility and attract more programmers.


The speed of the code’s execution is an important consideration while developing software. When it comes to speed, Julia is on par with the popular C language. The goal in making it was to make a short language. When it comes to speeding up code, Julia is not an interpreted language. Julia’s code is compiled using the LLVM framework. Julia can tackle speedy performance concerns without the need for manual profiling and optimization techniques. When faced with problems in the areas of Big Data, Cloud Computing, Data Analysis, and Statistical Computing, Julia offers an outstanding answer. It is evident that Julia is more efficient and faster than Python.


Each and every programming language requires community support to thrive. An abundance of helpers implies a wealth of tools to overcome difficulties. The Julia programming language is relatively new, and its small but growing community is very active. Contrarily, Python has been around for a while and has a sizable user base. When comparing Julia with Python, the former is preferable due to its robust community support, while the latter is still in its infancy. The Python community is quite helpful for finding solutions to problems and answers to concerns about programming.


Python has a large library that can be imported and used to perform common coding tasks with minimal effort. The lack of a comprehensive library collection is a drawback of Julia in comparison to Python. Furthermore, there are many external libraries available for use with Python. Unmaintained packages are another issue with Julia’s library. Julia can talk to C library code, however initial data plotting can be slow. Given its infancy, the Julia programming language need more robust library support.

Dynamically Typed

Both Julia and Python are dynamically typed, which means that programmers can use variables without first declaring them. In contrast, programmers have the option of using Julia in either its static or dynamic typing modes, depending on the application at hand. For this reason, Julia is superior to Python.


Since it is simple to learn and use, Python is a versatile language. Because of its adaptability, Python is a great choice for a wide variety of programming tasks, including web scripting, development, and even automation. For developers, Python is the language of choice due to the wide availability of useful modules and frameworks that facilitate task completion and cut down on development time. While Python is more general-purpose, Julia excels at the specific kinds of programming problems that arise in the natural sciences.


Both Julia and Python are capable of performing the tasks simultaneously. The serialization and deserialization of data across threads is essential for many Python-based approaches. However, Julia uses more complex and parallel methods. Furthermore, Julia is less useful as a programming language because of its less top-heavy parallelization grammar than Python.

Aiding Equipment

Any programmer will tell you that their preferred language is the one that offers the best tools support for their particular software development project. When compared to Julia, Python is superior due to its wider availability of useful tools. Tools in Python are very well developed, while those in Julia are still in the development stages. Therefore, unlike Python, Julia lacks a robust set of tools for identifying and fixing performance issues. In addition, the risk of an unsafe interface is increased in the case of Julia because it is a novel language with native APIs.

Partnering with Shell

When it comes to working in the shell, Julia is far and away the best language. This is due to Julia’s progress toward whole-person consciousness. Exporting Julia variables to the surface as an environment variable is a simple process. With shell commands, you can read and edit any file you choose. In general, Julia simplifies shell integration and operation to a great extent.

Change of Codes

With Julia, code translation is simple and well-supported. While it’s easy to port Python or C code to Julia, the same cannot be said for the other way around. Python to C and C to Python code conversion is difficult. It’s simple to link Julia together with C or Fortran libraries. There is a way to port Julia scripts to Python called “Pycall,” which allows for easy cross-language collaboration.

Functionality for Data Science

Since she aids in resolving mathematical programming issues, Julia has gained a larger fan base in the scientific community. The Julia community is different from the Python community since it focuses more on application development. With regards to practicality in data science, Julia is unrivaled. Programmers appreciate Julia’s accessibility because of its syntax, which is more akin to mathematical equations, making Julia an ideal language for both coding and solving mathematical problems. It’s true that Python is more beginner-friendly, but in the scientific world, Julia reigns supreme.

Collecting and Deciphering

Instead of being an interpreted language, Julia is compiled. The LLVM framework is used for collection, which improves execution speed but introduces problems during recompilation. Python, in contrast, is an interpreted language that may be used without first compiling the code.

The primary motivation for developing Julia was the need for a more efficient programming language to do Machine Learning and mathematical computations. Recent years have seen Julia’s rise in popularity among Machine Learning Engineers and Data Scientists due to its useful features. However, when contrasting Julia to Python, the latter is preferred due to Python’s longer history, larger and more active developer community, and wider availability of supplementary resources.

But Julia is a formidable opponent to Python due to its faster processing and easier code translation. In contrast, Python gets faster over time. Julia has several advantages over Python, but as Julia is still developing, most programmers, data scientists, and students use Python instead. If your work involves a lot of mathematics, Julia is the language for you.
