The Use of Python in Data Science

When contemplating data science, Python invariably takes the lead. Its ascent within the IT community has been nothing short of meteoric, establishing itself as a straightforward yet feature-rich language capable of powering a gamut of applications, ranging from essential web services to the Internet of Things (IoT), game development, and even the intricate realm of artificial intelligence.

Furthermore, Python is now making substantial inroads into the domains of big data and data analytics. This Python data science tutorial investigates the reasons behind Python's utilisation in big data applications. It is indeed true that numerous programming languages offer viable options for executing data science tasks, rendering it a daunting task to select a single language for the job. Nevertheless, the data provides valuable insights into these languages, making their mark in data science. There is no more compelling evidence than the data when it comes to unveiling the outcomes of comparing various data science tools.

Advantages of Python Over Other Languages in Data Science

Python code is crafted remarkably naturally, enhancing its readability and comprehensibility. This intrinsic quality is a critical factor in its popularity in data science.

Python's popularity in data science can be attributed to several notable features:

Ease of Learning:

Python is widely recognised for its beginner-friendly nature. Its simplicity and clarity make it accessible to anyone seeking to learn programming. 


Python stands out for its scalability, surpassing other languages like R. It also boasts faster performance than MATLAB or Stata. Notably, even platforms as extensive as YouTube have embraced Python due to its problem-solving flexibility.

Availability of Data Science Libraries:

The abundance of specialised libraries such as pandas, statsModels, NumPy, SciPy, and sci-kit-learn further augments Python's prowess in data science. These libraries continuously evolve, addressing challenges faced by developers and providing robust solutions.

Graphics and Visualisations:

Python offers various graphic and visualisation options that facilitate insightful data exploration. Matplotlib is a foundational plotting library, complemented by others like Seaborn, pandas, and ggplot. These packages empower users to gain deeper insights, generate charts, create graphical plots, develop web-ready interactive visuals, and more, all with ease.

Python Libraries for Data Science:

Python has garnered immense popularity as a versatile, high-level programming language suitable for prototyping and application development. Its readability, flexibility, and applicability in data science have made it a top choice among developers.
Developers extensively employ Python for creating games, standalone desktop applications, mobile apps, and various enterprise solutions.

Python libraries are pivotal in simplifying complex tasks, facilitating data integration with concise code, and reducing development time. Python boasts a vast repository of over 137,000 libraries, which are highly effective and frequently used to satisfy the various needs of customers and enterprises. These libraries have empowered scientists and developers to analyse vast datasets, derive insights, make informed decisions, and much more.

Below are some prominent Python libraries commonly used in fields related to data science:


NumPy is an expansive Python library designed for scientific computations. It offers advanced features, N-dimensional array objects, tools for interfacing with C/C++ and Fortran code, mathematical functions (e.g., linear algebra), random number generation capabilities, and more. NumPy is a versatile container for handling diverse data types and facilitates data loading and exporting.


SciPy is another essential Python library catering to developers, researchers, and data scientists. It encompasses optimisation, statistics, linear algebra, and integration packages for numerical computations. SciPy is particularly beneficial for individuals starting their careers in data science as it aids in various numerical tasks.


Matplotlib is a widely-used Python plotting library extensively utilised by data scientists to create various figures in various formats, depending on platform compatibility. It enables the creation of scatter plots, histograms, bar charts, and more, providing high-quality 2D and basic 3D plotting capabilities.


Pandas is a powerful open-source Python library for data manipulation, often called the Python Data Analysis Library. Based on NumPy's foundation, Pandas leverages DataFrames as the primary data structure, facilitating efficient handling and storage of tabular data. Pandas excel in tasks such as data merging, reshaping, aggregation, splitting, and data selection.


Blaze extends the capabilities of NumPy and Pandas to distributed and streaming datasets. It can access data from various sources, including bcolz, MongoDB, SQLAlchemy, Apache Spark, PyTables, and more. In conjunction with Bokeh, Blaze becomes a potent tool for creating compelling visualisations and dashboards for large datasets.
