Data science is an emerging, multidisciplinary field of scientific methods, processes, algorithm development and technology to extract knowledge or insights in ingenious ways from structured or unstructured data.
At the heart of data science is data. Buckets loads of it, streaming in and stored in enterprise data warehouses. According to IBM, globally, we currently generate over 2.5 quintillion bytes of data every single day. This data ranges from molecular biology to social media activity, astronomy, climate monitoring to health care. Large data sets are now generated by almost every activity in science, society, and commerce. There’s much to learn by mining that data, finding patterns and making predictions from this data. Data science is ultimately about asking interesting questions, and then finding answers using data that add value.
So what does a data scientist do? Well, they take a huge mass of data points and apply mathematics and programming to clean, massage, and organize the data into something meaningful. Data science dives in at a granular level to mine and understand complex behaviours, trends, and inferences. The best data scientists enjoy problem-solving, have strong analytical and statistical skill sets, technology skills, and have business acumen.
Python is arguably the go-to programming language for data scientists, particularly in industry (R is also very popular). Companies worldwide are frequently turning to Python to gain valuable insights from their data and get a competitive edge. Python is easy to learn, there’s excellent support, and there’s a Python interface available for almost all good data science libraries and machine learning frameworks. It’s an excellent language for data science mainly because of its wide range of libraries for storing, manipulating, and gaining insight from data.
There are so many excellent open source Python tools targeted at data science that the choice can be perplexing to say the least.
