PowerQuery Guide to Pandas
A Comparative Approach to Learn Pandas
About the Book
PowerQuery Guide to Pandas is designed to make readers familiar with the syntax and core concepts of Python language and the Pandas library by relating readers to familiar concepts in PowerQuery for Excel and PowerBI. With this book, I'll provide a comparative approach to learning Pandas and hopefully serve as good introduction to the Python language.
Learn the following concepts and topics in this book
* Data Types
* Input and Output
* Control Structures
* Structured Data Records
* Data Wrangling
* Dealing with Missing Data
* Grouping Data
* Combining Data
* ... and much more!
PowerQuery is great tool and should be part of every accountant's toolbox. However, Python is more mature and has wider reach in data analytics, processing, and automation. Level up your skills by learning Python and Pandas with the help of this book!
Today's business environment is becoming more and more data-driven. Stay relevant.
