Data science is an interdisciplinary field that focuses on computational statistics on data of various kinds that include either structured or unstructured,similar to data mining. Data science uses advanced methods to extract insights from data using various driving technologies like Python and R programming language.
Python is a high level and object oriented scripting language. It is used as general purpose programming language. It is interpreted and interactive language. It has huge standard of libraries compared to all other languages. Python is dominantly used in Data sciences,Machine Learning,Deep Learning and Artificial Intelligence as a NexGen technology.
Machine Learning in simple terms(not over simplified) is all about, making the system PREDICT & CONTROL , trained by a set of examples , is a subset of Artifical Intelligence & subsymbolic in nature. It is the corner stone of succesful e-commerce & Intelligent systems and Analytics. also it is the crux of Data science. ML, inturn depends on Statistics and computer Science
