Python Data Cleaning and Preparation Best Practices - A practical guide to organizing and handling data from various sources and formats using Python

Maria Zervou

Sinossi

Professionals face several challenges in effectively leveraging data in today's data-driven world. One of the main challenges is the low quality of data products, often caused by inaccurate, incomplete, or inconsistent data. Another significant challenge is the lack of skills among data professionals to analyze unstructured data, leading to valuable insights being missed that are difficult or impossible to obtain from structured data alone.To help you tackle these challenges, this book will take you on a journey through the upstream data pipeline, which includes the ingestion of data from various sources, the validation and profiling of data for high-quality end tables, and writing data to different sinks. You’ll focus on structured data by performing essential tasks, such as cleaning and encoding datasets and handling missing values and outliers, before learning how to manipulate unstructured data with simple techniques. You’ll also be introduced to a variety of natural language processing techniques, from tokenization to vector models, as well as techniques to structure images, videos, and audio.By the end of this book, you’ll be proficient in data cleaning and preparation techniques for both structured and unstructured data.

The Wood That Built London - A...

C.J. Schüler

It is hard to imagine that the busy townscape of South London was once a great wood, stretching almost seven miles from Croydon to Deptford or that, scattered through the suburbs, from Dulwich to Norwood, a number of oak woodlands have survived since before the Norman Conquest. These woods were intensively managed for a thousand years, providing timber for construction, furniture and shipbuilding, and charcoal for London's blacksmiths, kilns and bakeries. Now they afford important green space, a vital habitat for small mammals, birds and insects. 
 
Drawing on a wealth of documents, historic maps and environmental evidence, The Wood That Built London charts the fortunes of the North Wood from its earliest times: its ecology, ownership, management, and the gradual encroachment of the metropolis.
