If you want to speed up some existing Python code, writing a compiled extension in Rust can be an excellent choice: In many situations, Rust code can run much faster than Python. Rust prevents most of the memory-management bugs that often occur in C, C++, and Cython code. There is a growing ecosystem of third-party Rust packages available, and unlike C and C++ it also has a built-in package manager and build system. However, if you just want to prototype […]

Do you want to optimize the performance of your Python program to make it run faster or consume less memory? Before diving into any performance tuning, you should strongly consider using a technique called software profiling. It may help you answer whether optimizing the code is necessary and, if so, which parts of the code you should focus on. Sometimes, the return on investment in performance optimizations just isn’t worth the effort. If you only run your code once or […]

The final release of Python 3.12 is scheduled for October 2023, which is growing closer. In the meantime, you can download and install its preview version to get a sneak peek at the upcoming features. One of the biggest changes announced is support for the Linux perf profiler, which is a powerful performance profiling tool. To fully benefit from using the perf profiler in Python 3.12, you should have a fairly good understanding of how the underlying hardware and the […]

With many businesses turning to Python’s powerful data science ecosystem to analyze their data, understanding how to avoid introducing bias into datasets is absolutely vital. If you’ve studied some statistics, then you’re probably familiar with terms like reporting bias, selection bias, and sampling bias. There’s another type of bias that plays an important role when you’re dealing with numeric data: rounding bias. Understanding how rounding works in Python can help you avoid biasing your dataset. This is an important skill. […]
