Why Do Data Scientists and Machine Learners Use Python?

Python is the most widely used programming language for ML and DS implementation. Let's look at why Python is so popular among Data Scientists and ML Engineers.

Learning is simple:

Python has a fairly basic syntax. It can use to do simple computations. E.g., adding two strings to more sophisticated procedures like developing Machine Learning models.

Fewer lines of code

Putting Data Science and ML into practice needs a large number of algorithms. We don't have to code algorithms thanks to Python's support for pre-defined packages. To make things even easier, Python has a "check as you code" technique. So, it decreases the amount of time spent testing the code.

Libraries that have already there:

Python comes with many pre-built libraries for implementing ML & DL algorithms. To execute an algorithm on a data set, you only need to install and load the appropriate packages. E.g., NumPy, Keras, Pytorch, and other pre-built libraries.

Independent of Platform:

Python may operate on a variety of operating systems. So, including Windows, Mac OS X, Linux, Unix, and others. You may use tools like PyInstaller to take care of any dependency concerns. But, while migrating code from one platform to another.

Massive Public Support:

Python offers various communities, firms, and forums. Here, programmers may discuss their issues and support one another.
