Data science happens in code. The ability to write reproducible, robust, scaleable code is key to a data science project's success--and is absolutely essential for those working with production code. This practical book bridges the gap between data science and software engineering, clearly explaining how to apply the best practices from software engineering to data science. Examples are provided in Python, drawn from popular packages such as NumPy and pandas. If you want to write better data science code, this guide covers the essential topics you need (and that are often missing from introductory data science or coding classes), including how to: Understand data structures and object-oriented programming Clearly and skillfully document your code Package and share your code Integrate data science code with a larger codebase Write APIs Create secure code Apply best practices to common tasks such as testing, error handling, and logging Work more effectively with software engineers Write more efficient, maintainable, and robust code in Python Put your data science projects into production And more

Zoe Grey is between jobs, between boyfriends, and between crises. Things seem to be looking up. Until all she's looking at is trouble. Before she knows it, witnessing a brutal stabbing leads to a dead guy in her living room and a target on her back. Then she lands herself smack in the middle of Detective Ellmann's homicide investigation, becoming the only suspect. Now Zoe must stay ahead of those who want her dead and chase down her answers while working around Ellmann. As her determination to find justice for an innocent victim drives her on, she can feel the heat from the bullets flying in her direction. No stranger to trouble, Zoe just might find herself in over her head this time.

Bond enforcement agent Zoe Grey has seventy-two hours to find the elusive fugitive Danielle Dillon before the bond company is out fifteen grand. She's the last-ditch effort, and everyone knows it's a long shot. Ellmann is investigating the murder of a Fort Collins socialite which corresponds to a cross-country string of art thefts and soon draws the attention of the FBI. Zoe begins to suspect that her case is somehow connected to Ellmann's. And the deeper she digs, the deadlier things become. Can she get herself out of trouble and find Danille Dillon before the clock runs out?

When Sadie Salois asks Zoe Grey to investigate a strange coworker, Zoe hesitates. She's a bounty hunter, not a private investigator. But Zoe takes the job, certain it will be simple matter to put Sadie's worries to rest. Almost immediately Zoe discovers the woman she's investigating has no past, and that she's somehow connected to a missing high school teacher. As Zoe continues her investigation, she finds things are not what they seem. The case is much bigger than a woman using an assumed identity, and it is quickly spiraling out of control. As Zoe puts her skills to use finding a woman she's not sure is still alive, she realizes Sadie's coworker isn't strange; she's dangerous. And far more than one life is at stake.
