Key FeaturesUse the power of pandas to solve most complex scientific computing problems with easeLeverage fast, robust data structures in pandas to gain useful insights from your dataPractical, easy to implement recipes for quick solutions to common problems in data using pandasBook DescriptionPandas is one of the most powerful, flexible, and efficient scientific computing packages in Python. With this book, you will explore data in pandas through dozens of practice problems with detailed solutions in iPython notebooks.This book will provide you with clean, clear recipes, and solutions that explain how to handle common data manipulation and scientific computing tasks with pandas. You will work with different types of datasets, and perform data manipulation and data wrangling effectively. You will explore the power of pandas DataFrames and find out about boolean and multi-indexing. Tasks related to statistical and time series computations, and how to implement them in financial and scientific applications are also covered in this book.By the end of this book, you will have all the knowledge you need to master pandas, and perform fast and accurate scientific computing.What you will learnMaster the fundamentals of pandas to quickly begin exploring any datasetIsolate any subset of data by properly selecting and querying the dataSplit data into independent groups before applying aggregations and transformations to each groupRestructure data into a tidy form to make data analysis and visualization easierPrepare messy real-world datasets for machine learningCombine and merge data from different sources through pandas SQL-like operationsUtilize pandas unparalleled time series functionalityCreate beautiful and insightful visualizations through pandas direct hooks to matplotlib and seabornAbout the AuthorTheodore Petrou is a data scientist and the founder of Dunder Data, a professional educational company focusing on exploratory data analysis. He is also the head of Houston Data Science, a meetup group with more than 2,000 members that has the primary goal of getting local data enthusiasts together in the same room to practice data science. Before founding Dunder Data, Ted was a data scientist at Schlumberger, a large oil services company, where he spent the vast majority of his time exploring data.Some of his projects included using targeted sentiment analysis to discover the root cause of part failure from engineer text, developing customized client/server dashboarding applications, and real-time web services to avoid the mispricing of sales items. Ted received his masters degree in statistics from Rice University, and used his analytical skills to play poker professionally and teach math before becoming a data scientist. Ted is a strong supporter of learning through practice and can often be found answering questions about pandas on Stack Overflow.Table of ContentsPandas FoundationsEssential DataFrame OperationsBeginning Data AnalysisSelecting Subsets of DataBoolean IndexingIndex AlignmentGrouping for Aggregation, Filtration and TransformationRestructuring Data into Tidy FormJoining multiple pandas objectsTime SeriesVisualization
