This is, however, an important task, and is a prerequisite to the rest of the data analysis workflow, including visualization, analysis and reporting. Python and R are considered a popular choice of tool for data analysis, and have packages that can be best used to manipulate different kinds of data, as per your requirements. This book will show you the different data wrangling techniques, and how you can leverage the power of Python and R packages to implement them.\u003c\/p\u003e\u003cp\u003eYou'll start by understanding the data wrangling process and get a solid foundation to work with different types of data. You'll work with different data structures and acquire and parse data from various locations. You'll also see how to reshape the layout of data and manipulate, summarize, and join data sets. Finally, we conclude with a quick primer on accessing and processing data from databases, conducting data exploration, and storing and retrieving data quickly using databases.\u003c\/p\u003e\u003cp\u003eThe book includes practical examples on each of these points using simple and real-world data sets to give you an easier understanding. By the end of the book, you'll have a thorough understanding of all the data wrangling concepts and how to implement them in the best possible way.\u003c\/p\u003eStyle and approach\u003cp\u003eThis is a practical book on data wrangling designed to give you an insight into the practical application of data wrangling. It takes you through complex concepts and tasks in an accessible way, featuring information on a wide range of data wrangling techniques with Python and R\u003c\/p\u003e","brand":"Packt Publishing","offers":[{"title":"Default Title","offer_id":47135768117488,"sku":"9781787283671","price":23.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781787283671_p0.jpg?v=1763738161","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781787283671","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
