This is why data scientists prefer Python.<\/p>\n<p>Out there, there\u2019s a battle taking place in the minds of<strong> future Data scientists<\/strong> for choosing the best tools. Though there are quite a number of tools with many options, the choice narrows down to two popular languages \u2013 Python and R.<\/p>\n<h3>Why Python over R for Data Science?<\/h3>\n<p>One of the pushes for choosing Python over R is the variety of data science\/data analytics libraries made available. Some of the libraries are well-known in the data science community &#8211; Pandas, StatsModels, NumPy, SciPy, and Scikit-Learn. It doesn\u2019t stop there; some 72,000 of them are in the Python Package Index (PyPI) and are still growing constantly. After all this, I recommend that you check the <a href=\"https:\/\/data-flair.training\/blogs\/r-vs-python-for-data-science\/\" target=\"_blank\" rel=\"noopener\"><em><strong>difference between Python and R<\/strong><\/em><\/a> for better understanding<\/p>\n<p>So, before we start our topic, I recommend that you take a brief of what data science is.<\/p>\n<h3>What is Data Science?<\/h3>\n<p>Data science, aka data-driven science, is an interdisciplinary field of scientific methods, processes, and systems. It is used to extract knowledge or insights from data in various forms, either structured or unstructured. In this way, it is similar to data mining. With data at its heart, it employs a wide range of techniques on the data to extract essential insights from it.<\/p>\n<h3>Data science is attracting beginners towards Python. How?<\/h3>\n<p>For this reason and others,<a href=\"https:\/\/data-flair.training\/blogs\/why-is-python-in-demand\/\" target=\"_blank\" rel=\"noopener\"><em><strong> Python is the most demanding for programmers<\/strong><\/em><\/a>. Data scientists coming from engineering or scientific backgrounds might feel a bit out of place the first time they try to use it for data analysis, but when they do use it, they make the most out of it. Python didn\u2019t make its inroads into data science initially when it was conceived in the late 1980s. Tools for covering every aspect of scientific computing are now readily available in Python.<\/p>\n<p><a href=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2018\/02\/Python-Libraries-for-Data-Science2.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-63158\" src=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2018\/02\/Python-Libraries-for-Data-Science2.jpg\" alt=\"Python for data science\" width=\"802\" height=\"420\" srcset=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2018\/02\/Python-Libraries-for-Data-Science2.jpg 802w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2018\/02\/Python-Libraries-for-Data-Science2-150x79.jpg 150w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2018\/02\/Python-Libraries-for-Data-Science2-300x157.jpg 300w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2018\/02\/Python-Libraries-for-Data-Science2-768x402.jpg 768w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2018\/02\/Python-Libraries-for-Data-Science2-520x272.jpg 520w\" sizes=\"auto, (max-width: 802px) 100vw, 802px\" \/><\/a><\/p>\n<p>Python\u2019s readability and simplicity make it comparatively easy to pick up. The number of dedicated and analytical libraries freely available for download today means that data scientists present in every sector will find packages already tailored to their needs.<\/p>\n<p>In addition to coding skills, mastering Python for data science also includes version control with Git, working with APIs, and automating workflows. These are practical skills that make your life easier as a data professional. You can schedule your data jobs, connect to web services, and even create simple dashboards using Python. Mastery is not about knowing everything\u2014it\u2019s about being able to solve data problems in an efficient, reliable, and repeatable way.<\/p>\n<p>In short, we can say Python has become the go-to language for data scientists.

From importing data from spreadsheets to processing sets for time-series analysis, Pandas is used for everything. Pandas pretty much convert one data form to another at your fingertips. Hence, Pandas powerful data frames can perform both basic cleanup and advanced data manipulations.<\/p>\n<blockquote><p><em><strong><span style=\"color: #ff6600\">\u201cOne of the reasons we like to use Pandas is because we like to stay in the Python ecosystem,\u201d Burc Arpat, a quantitative engineering manager at Facebook.<\/span><\/strong><\/em><\/p><\/blockquote>\n<p>Behind Python\u2019s data science success story, one of the earliest libraries is Numpy (Numerical Python), on which Pandas is built. NumPy\u2019s functions are used in Pandas for advanced analysis. For more specialization, one can use Scipy, which is scientifically equivalent to Numpy, offering tools and techniques for scientific data analysis.<\/p>\n<h4>2. Python NumPy<\/h4>\n<p>NumPy facilitates easy and efficient numeric computation. It has many other libraries built on top of it. Make sure to learn NumPy arrays.<\/p>\n<h4>3. Python SciPy<\/h4>\n<p><strong><a href=\"https:\/\/www.scipy.org\/\">SciPy<\/a><\/strong> will give you all the tools you need for scientific and technical computing.
