Python is an interpreted language, so the instructions written on it do not require compiling in order to be executed. With the required interpreter, Python software can run on Windows, Linux, or any operating system, which enables a cross-platform advantage. Besides, Python is included in the majority of Linux distributions and Unix-like operating systems.

Numerous community of enthusiasts

The large quantity of active supporters is the main driving force for the continued improvement of Python over the last 30 years. The role of the community lies not only in maintaining and enhancing the language, but also in sharing experience and searching for practical solutions. This is particularly beneficial for novice Python developers who may easily get multiple guides and manuals, as well as specific advice on creating software with Python.

Python for Big Data Projects

Among various spheres of implementation, Big Data is perhaps the one most closely associated with Python. Regardless of industries, these Python big data projects usually cover at least one of the following activities:

  • data mining,
  • predictive analysis of data,
  • data personalization,
  • data safety.

Python and big data are a perfect match that offers its advantages to several industries reliant on big data that will be examined below. Here are a few examples of the beneficial practical results achieved by developers and end users that deal with big data using Python:

  • fewer errors in the code, meaning a shorter phase of QA, thanks to the simple nature of the language;
  • versatility and fast building of prototypes and ready solutions, due to the availability of comprehensive manuals and libraries, such as scikit learn for machine learning, pandas for data analysis, pyrisk for performance and risk analysis, and many others;
  • wide integration possibilities with other software, thanks to the popularity of Python, and the presence of such implementations as CPython, Jython, IronPython, and so on;
  • reliable performance coupled with less coding time that results from the shorter syntax of Python and allows faster problem solving.
