Why Python is the First Choice for The Data Science Engineers?

Data science has become an indispensable field, empowering us to extract knowledge and insights from the ever-growing ocean of data. Python has emerged as a dominant force in the field of data science, revolutionizing the way we analyze and extract insights from vast datasets. Although it is a general-purpose programming language, it's becoming more and more popular for doing data science. In this article, we explore how Python's versatility, simplicity, and rich ecosystem of libraries empower data scientists to tackle complex analytical challenges with ease.

Python for Data Science

Companies worldwide are using Python to harvest insights from their data and get a competitive edge. In recent years, the huge community around this open source language has created quite a few tools to effectively work with Python. A number of tools have been built specifically for data science. As a result, analyzing data with Python has been easier. The tools you choose depends on the requirements you need for coding. This language is synonymous with flexibility, powerful yet easy to use features. Python has its USP in the rich set of utilities and the libraries it offers for analytics and data processing tasks. Here are few important reasons why Python continues to reign supreme as the first choice for data science engineers.

1. Versatility of Python

Python's versatility as a general-purpose programming language makes it well-suited for various tasks, including data manipulation, statistical analysis, machine learning, and visualization. Python also has different data structures that help in data science. Some of the data structures are -

  • Tuples - Tuples are described by the elements or values separated by commas. The values in the tuple cannot be changed or modified. They work much quicker than lists.
  • Lists - Lists are flexible data structures of Python that have the features to change each element of the list. A list can be described by writing a list of elements or values separated by the comma within the square brackets.
  • Dictionary - Dictionary is an unordered set of keys. The keys need to be unique to make the set as the dictionary. A dictionary contains a set of unique values. An empty dictionary is made up of a pair of braces.
  • Strings - Strings in Python are defined by commas. It may be single, double or triple inverted comma. Triple comma quotes are used for docstrings for multiple lines.  Once the value is added to the strings, it cannot be changed.

All the above data structures play an important role in Python whether it an addition of elements or values into the program or any other operations.

2. Rich Ecosystem of Libraries

Python boasts a vast and diverse ecosystem of libraries specifically tailored for data science tasks. Libraries such as NumPy, Pandas, Matplotlib, and Scikit-learn provide essential functionalities for data manipulation, analysis, visualization, and machine learning. These libraries streamline the data science workflow, enabling engineers to prototype, experiment, and deploy solutions with efficiency and ease. Here are some important libraries for data science.

  • NumPy: NumPy is a fundamental library for numerical computing in Python, providing support for multidimensional arrays, mathematical functions, and linear algebra operations essential for data manipulation and analysis.
  • Pandas: Pandas is a powerful data manipulation and analysis library that offers data structures such as DataFrame and Series, enabling users to clean, transform, and analyze tabular data efficiently.
  • Matplotlib and Seaborn: Matplotlib and Seaborn are visualization libraries that facilitate the creation of insightful charts, plots, and graphs to communicate data-driven insights effectively.
  • Scikit-learn: Scikit-learn is a comprehensive machine learning library that offers a wide range of algorithms for classification, regression, clustering, dimensionality reduction, and model evaluation.
  • TensorFlow and PyTorch: For deep learning applications, these libraries offer powerful tools to build and train complex neural networks.

These libraries, along with countless others, provide pre-built functionality, saving data scientists hours of development time and ensuring consistency across projects.

3. Ease to Learn

Compared to other languages Python is easy to learn even for non-programmers. It makes an ideal first language due to three primary reasons - ample learning resources, readable code and large community. All these translate to a gradual learning curve with direct application of concepts in real-world programs.

4. Compatibility with Hadoop

Hadoop is the most popular open-source big data platform and the inherent compatibility of Python is yet another reason to prefer it over other languages. The PyDoop package offers access to the HDFS API for Hadoop and hence allows to write Hadoop MapReduce programs and applications. Using HDFS API you can connect your program to an HDFS installation thus, making it possible to read, write and get information on files, directories, and global file system properties.

5. Write Less Do More

Python is known for making programs work in the least lines of code. It automatically identifies and associates data types and follows an indentation based nesting structure. Overall the language is easy to use and takes less time in coding. There is also no limitation to the data processing. You can compute data in commodity machines, laptop, cloud, desktop, basically everywhere.

6. Powerful Data Manipulation and Analysis Tools

Pandas, a cornerstone of Python's data science ecosystem, offers data structures such as DataFrame and Series that facilitate robust data manipulation and analysis. With Pandas, engineers can clean, transform, and explore datasets with ease, paving the way for insightful insights and informed decision-making.

7. Data Visualization

With recent packages, Python has improved and now it has many cool APIs like Plotly and libraries like Matplotlib, ggplot, Pygal, NetworkX etc. that can create breathtaking data visualizations. You can even use TabPy to integrate Tableau and use win32com and Pythoncom to integrate Qlikview, both are popular big data visualization tools.

8. Day-to-Day Tasks

The day-to-day tasks of a data scientist involve many interrelated but different activities such as accessing and manipulating data, computing statistics and creating visual reports around that data. The tasks also include building predictive and explanatory models, evaluating these models on additional data, integrating models into production systems, among others. Python has a diverse range of open source libraries for just about everything that a Data Scientist does on an average day.

9. Community Support and Collaboration

Python boasts a vibrant community of developers, data scientists, and researchers who actively contribute to the development of libraries, share knowledge, and provide support through forums, conferences, and online communities.

10. Open-Source Nature

Python's open-source philosophy fosters collaboration and innovation, allowing users to leverage the collective expertise of the community to address challenges, improve existing tools, and advance the field of data science.

11. Interactive Development Environments

Python's support for interactive development environments (IDEs) and notebooks, such as Jupyter Notebook and Google Colab, enhances the data science workflow. These tools facilitate iterative exploration, experimentation, and collaboration, empowering engineers to visualize data, document workflows, and share insights with colleagues and stakeholders.

12. Real-World Applications

Python's versatility and robustness have led to its widespread adoption across industries, including finance, healthcare, retail, and technology. From predictive analytics and natural language processing to image recognition and recommendation systems, Python powers a myriad of data-driven applications that drive innovation and impact.


In conclusion, Python's versatility, extensive library ecosystem, ease of learning, powerful data manipulation and analysis tools, comprehensive machine learning support, interactive development environments, strong community support, and real-world applications make it the first choice for data science engineers. As the demand for data-driven insights continues to rise, Python remains indispensable in empowering engineers to extract value from data and drive transformative change in the digital age.
