Artificial Intelligence (AI) and Machine learning (ML) are our daily companions, and it isn't easy to imagine life without algorithms and statistical models. Python is the first thing that springs to mind whenever we hear the term Machine Learning. These technologies have a history of aiding the tech world and a lengthy association.

Python is possibly the most delicate machine learning language, with48.24% of developers using it. Python is superior in all areas of scientific computing due to its low-level packages and well-designed high-level APIs, but it has some drawbacks when used for specific tasks. Therefore, Python alternatives were needed, and their demand was universal.

Multiple emerging languages now perform equally or outperform Python. Hence, it's no longer the only machine learning option. Scala, Julia, MQL5, and other languages that are not Python superset, can be used to develop and provide machine learning applications. Therefore, machine learning isn't limited to Python anymore.

In this article, we will explore the emergence of new machine learning languages, how they have eroded Python's market share, and the shift in the future of machine learning.

The Disadvantages of Python

Let's discuss a few of the drawbacks of Python that developers and data scientists commonly confront.

Performance & Speed

Python is fast for development but slows at computation. It uses an interpreter instead of a compiler as an interpreted language. Due to sequential code execution, it's slower than other data science programming languages. Python is slower than C, which has many useful tools and libraries. Unless you master vectorized code, you'll notice how slow it is.

Cython, a superset of Python that executes Python code compiled into C, gives you C's speed without adding more computing resources. Many programmers use Cython to write Python code as fast as C but more concise and readable.

Design Restrictions

Python's design limitations are a significant issue. Its dynamic typing causes this constraint. Dynamically typed code doesn't require declaring variable types. Python employs duck-typing, a confusing feature. According to the duck-typing principle, anything resembling a duck is a duck. In duck typing, an object's class or type is less important than its function. Duck Typing needs no type checking. You can also verify a process or attribute.

Inefficient Memory Consumption

Python uses a lot of memory due to its large structures. Besides, Python data types are flexible with memory consumption. Python isn't suitable for memory-intensive tasks. Python's flexible data types also cause memory consumption. As a result, memory management in Python becomes challenging as you create large and long-running Python systems.

Threading Deficiency

Python threading is less efficient than other languages. Even though Python is multithreaded, it executes code one thread at a time. Hence, multithreaded Python gives you single-threaded efficiency. Python has a Global Interpreter Lock (GIL), which only one thread can use concurrently. Only when Python uses a native library, many threads can run together. Also, multithreading is possible in Jython, a superset of Python, but not in Python.

Why Do Data Scientists Look for Python Alternatives?

Python is amazing. But it can't be the Flash and Incredible Hulk at the same time! Someone may need the Flash, and someone may need the Hulk to perform their tasks. Yes, the diversity in user requirements. Similarly, Python was not designed solely for mathematical and data science applications. It needs an external library like NumPy or Tensorflow, a library developed specifically for deep learning algorithms. Therefore, data-specific programming languages should be more advantageous than Python.

For instance, machine learning in business requires speed and scalability to reduce execution time. You cannot keep customers waiting. Hence, you need a speedier ML language to perform. The faster, the better.

Now, Python is fast, but is there anything faster than Python? Yes, it's Julia, also Scala!

And this is the type of circumstance in which the data scientists prefer to use a different programming language over Python.

Python Alternatives for Data Science

Several Python alternatives perform as well or better than Python in various application contexts. Here are some Python Data Science alternatives:

1. Julia

Julia is a brand-new, high-level dynamic programming language that is innovative, fast, and comfortable. However, it is a general-purpose language capable of writing various applications. Notably, a large portion of its package ecosystem and capabilities are geared at high-level numerical computing, which is perfect for machine learning.

Julia is built on multiple languages, including low-level programming languages such as C and high-level dynamic typing languages such as Python, R, and MATLAB. Julia reflects the optional typing, syntax, and features of these languages because Julia's goal was to combine their best elements and eliminate their shortcomings.

Julia's creators wanted a language that could handle Scientific computing, machine learning, data mining, large-scale linear algebra, and distributed and parallel computing as fast as C. However, they made something even more swift. Even though Python has gotten faster, Julia still beats it.

Julia simplifies the writing of the numerous mathematical symbols used in machine learning. It offers multiple GPU-programming packages, such as ArrayFire, which can let GPUs execute generic code. Each package has a unique programming model. For example, NVIDIA has CUDA.jl, AMD has AMDGPU.jland oneAPI.

Machine learning engineers can quickly deploy Julia across large clusters benefiting significantly from its potent tools, such as MLBase.jl, Flux.jl (deep learning), MLJ.j (general machine learning)  and Knet.jl (deep learning).Flux is a high-speed deep machine learning library that comes pre-installed with additional tools to maximize Julia's capability. Similarly, ScikitLearn.jl, TensorFlow.jl, and MXNet.jl, appropriate for ML applications, are also included.

Julia excels at solving complex computational issues. Thus, numerous prestigious institutions, including,Stanford, and Tokyo Metropolitan University, offer Julia courses. It also stands firm in the Python vs. Julia comparison.
