Overview of this book

Data analysis enables you to generate value from small and big data by discovering new patterns and trends, and Python is one of the most popular tools for analyzing a wide variety of data. With this book, you’ll get up and running using Python for data analysis by exploring the different phases and methodologies used in data analysis and learning how to use modern libraries from the Python ecosystem to create efficient data pipelines. Starting with the essential statistical and data analysis fundamentals using Python, you’ll perform complex data analysis and modeling, data manipulation, data cleaning, and data visualization using easy-to-follow examples. You’ll then understand how to conduct time series analysis and signal processing using ARMA models. As you advance, you’ll get to grips with smart processing and data analytics using machine learning algorithms such as regression, classification, Principal Component Analysis (PCA), and clustering. In the concluding chapters, you’ll work on real-world examples to analyze textual and image data using natural language processing (NLP) and image analytics techniques, respectively. Finally, the book will demonstrate parallel computing using Dask. By the end of this data analysis book, you’ll be equipped with the skills you need to prepare data for analysis and create meaningful data visualizations for forecasting values from data.

Reading and writing data from Redis

Redis is an open-source NoSQL database. It is a key-value database, in-memory, extremely fast, and highly available. It can also be employed as a cache or act as a message broker. In-memory means it uses RAM for the storage of data and handles bigger-sized data using virtual memory. Redis offers a cache service or permanent storage. Redis supports a variety of data structures, such as string, set, list, bitmap, geospatial indexes, and hyperlogs. Redis can deal with geospatial, streaming, and time-series data. It is offered with cloud services such as AWS and Google Cloud.

We can read and write data in Python from Redis using the Redis connector. For this connectivity purpose, we need to install Redis and the Redis connector. You can download Redis from the following link: Redis is a pure Python Redis client library that can be installed using pip:

pip install redis
