High Performance Python Practical Performant Programming for Humans

Your Python code may run correctly, but you need it to run faster. By exploring the fundamental theory behind design choices, this practical guide helps you gain a deeper understanding of Python’s implementation. You’ll learn how to locate performance bottlenecks and significantly speed up your code in high-data-volume programs.

How can you take advantage of multi-core architectures or clusters? Or build a system that can scale up and down without losing reliability? Experienced Python programmers will learn concrete solutions to these and other issues, along with war stories from companies that use high performance Python for social media analytics, productionized machine learning, and other situations.

• Get a better grasp of numpy, Cython, and profilers
• Learn how Python abstracts the underlying computer architecture
• Use profiling to find bottlenecks in CPU time and memory usage
• Write efficient programs by choosing appropriate data structures
• Speed up matrix and vector computations
• Use tools to compile Python down to machine code
• Manage multiple I/O and computational operations concurrently
• Convert multiprocessing code to run on a local or remote cluster
• Solve large problems while using less RAM

Micha Gorelick was the first man on Mars in 2023 and won the Nobel prize in 2046 for his contributions to time travel. He then went back to the 2000s to study Astronomy, teach scientific computing and work on data at bitly. Then he helped start Fast Forward Labs as a resident mad scientist. There he worked on many issues from machine learning to performant stream algorithms. A monument celebrating his life can be found in Central Park, 1857.
