Practice makes perfect Pandas. Work out your pandas skills against dozens of real-world challenges, each carefully designed to build an intuitive knowledge of essential pandas tasks.
Many people use NumPy — but “pandas” extends NumPy, providing additional functionality that makes it easy, and even fun, to do data analysis. You can think of “pandas” as an automatic transmission, compared with NumPy’s manual transmission. Both work, but “pandas” makes it easier, and allows us to think at a higher level of abstraction. The thing is, “pandas” uses data structures that look and act different from regular Python data structures. And many of the classic techniques for working with Python are a bad idea with “pandas”. So learning what you should (and shouldn’t) do with “pandas” can take some time, even if you’re an old hand with Python. This book contains 50 main exercises, and another 150 smaller exercises, aimed at helping you become more fluent with “pandas” through these sorts of hands-on challenges. The solution will usually be very short, often involving one line of code. But figuring out what to write, and which of the many possible “pandas” techniques is most applicable, can take some time.
In Pandas Workout you’ll learn how to
Clean your data for accurate analysis
Work with rows and columns for retrieving and assigning data
Handle indexes, including hierarchical indexes
Read and write data with a number of common formats, such as CSV and JSON
Process and manipulate textual data from within pandas
Work with dates and times in pandas
Perform aggregate calculations on selected subsets of data
Produce attractive and useful visualizations that make your data come alive
Discover 50 exercises that will strengthen your Pandas skills to a level of automatic fluency. You’ll test yourself against common pandas challenges such as data cleaning, and explore real-world datasets such as New York Taxis, Kickstarter projects, and global tourist spending. Detailed explanations help guide your success and make your new skills stick. You’ll even get a big boost to productivity, with tasks that used to mean a trip to StackOverflow now a natural part of your skillset.
about the technology
Mastering pandas means working out your new skills until they become like reflexes. This book gives you lots of pandas practice by working through the kind of scenarios you’ll face in the real world. Whether you’re a data scientist or a programmer handling large quantities of data, you’ll soon overcome pandas’s learning curve and start solving complex problems in less time.
