Data Analysis with Python

By: David Taieb

Overview of this book

Data Analysis with Python offers a modern approach to data analysis so that you can work with the latest and most powerful Python tools, AI techniques, and open source libraries. Industry expert David Taieb shows you how to bridge data science with the power of programming and algorithms in Python. You'll be working with complex algorithms, and cutting-edge AI in your data analysis. Learn how to analyze data with hands-on examples using Python-based tools and Jupyter Notebook. You'll find the right balance of theory and practice, with extensive code files that you can integrate right into your own data projects. Explore the power of this approach to data analysis by then working with it across key industry case studies. Four fascinating and full projects connect you to the most critical data analysis challenges you’re likely to meet in today. The first of these is an image recognition application with TensorFlow – embracing the importance today of AI in your data analysis. The second industry project analyses social media trends, exploring big data issues and AI approaches to natural language processing. The third case study is a financial portfolio analysis application that engages you with time series analysis - pivotal to many data science applications today. The fourth industry use case dives you into graph algorithms and the power of programming in modern data science. You'll wrap up with a thoughtful look at the future of data science and how it will harness the power of algorithms and artificial intelligence.

Statistical exploration of time series


For the sample application, we'll use stock historical financial data provided by the Quandl data platform financial APIs (https://www.quandl.com/tools/api) and the quandl Python library (https://www.quandl.com/tools/python).

To get started, we need to install the quandl library by running the following command in its own cell:

!pip install quandl

Note

Note: As always, don't forget to restart the kernel after the installation is complete.

Access to the Quandl data is free but limited to 50 calls a day, but you can bypass this limit by creating a free account and get an API key:

  1. Go to https://www.quandl.com and create a new account by clicking on the SIGN UP button on the top right.

  2. Fill up the form in three steps of the sign-up wizard. (I chose Personal, but depending on your situation, you may want to choose Business or Academic.)

  3. At the end of the process, you should receive an email confirmation with a link to activate the account.

  4. Once the account is...
