• Build a strong data science foundation with the best data science tools available in Python
• Add value to yourself, your organization, and society by extracting actionable insights from raw data

Book Description

Practical Data Science with Python teaches you core data science concepts, with real-world and realistic examples, and strengthens your grip on the basic as well as advanced principles of data preparation and storage, statistics, probability theory, machine learning, and Python programming, helping you build a solid foundation to gain proficiency in data science.

The book starts with an overview of basic Python skills and then introduces foundational data science techniques, followed by a thorough explanation of the Python code needed to execute the techniques. You'll understand the code by working through the examples. The code has been broken down into small chunks (a few lines or a function at a time) to enable thorough discussion.

As you progress, you will learn how to perform data analysis while exploring the functionalities of key data science Python packages, including pandas, SciPy, and scikit-learn. Finally, the book covers ethics and privacy concerns in data science and suggests resources for improving data science skills, as well as ways to stay up to date on new data science developments.

By the end of the book, you should be able to comfortably use Python for basic data science projects and should have the skills to execute the data science process on any data source.

What you will learn

• Use Python data science packages effectively
• Clean and prepare data for data science work, including feature engineering and feature selection
• Data modeling, including classic statistical models (such as t-tests), and essential machine learning algorithms, such as random forests and boosted models
• Evaluate model performance
• Compare and understand different machine learning methods
• Interact with Excel spreadsheets through Python
• Create automated data science reports through Python
• Get to grips with text analytics techniques

Who this book is for

The book is intended for beginners, including students starting or about to start a data science, analytics, or related program (e.g. Bachelor's, Master's, bootcamp, online courses), recent college graduates who want to learn new skills to set them apart in the job market, professionals who want to learn hands-on data science techniques in Python, and those who want to shift their career to data science.

The book requires basic familiarity with Python. A "getting started with Python" section has been included to get complete novices up to speed.
