Insanely Low-Level A Gil Dabah Blog Archive for the ‘Python’ Category Newer Entries » Plugins’ Headache Sunday, June 10th, 2007 As I was writing a plugin, or to be more accurate, an extension module for Python in C/Win32; I had mysterious crashings here and there. Using a JIT I saw that the crash is in malloc/free so I looked at the stack and saw where’s the problem at (function scope). So far so good, piece of cake. Isolating the problematic code, yet I still didn’t fully understand why it

April 2009 by kay Building sets from set() and ANY When defining a regular expression there is a well known duality between a set of characters specified by enclosing characters or character ranges within square brackets `[…]` and defining the pattern of the complement set `[^…]` by preceding the caret symbol ^ . [0-9] — matches

profilehooks Decorators for profiling Python functions About Sometimes you want to profile just a single function in your Python program. The profilehooks module lets you do that very easily: #!/usr/bin/python from profilehooks import profile class SampleClass: @profile def silly_fibonacci_example(self, n): """Return the n-th Fibonacci number. This is a method rather rather than a function just to illustrate that you can use the 'profile' decorator on methods as well as global functions. Needless to say, th

# Characterizing Single-Statement Bugs in Popular Open-Source Python Projects Reviewed by Greg Wilson / 2022-03-11 Keywords: Bugs , Open Source , Python I spent most of an afternoon last week tracking down a bug caused by having two decorators stacked on a function in the wrong order. The fix was small, but the impact was not. Reading this paper has got me wondering how often this happens—how often it turns out that just one line in a program needs to change to make it right. Kamienski and colleagues se

Httpx vs Requests in Python. Performance and other Musings. Comparing the pypi requests vs httpx packages, who will fall on their face? Someone recently brought up the new kid on the block, the httpx python package for http work of course. I mean the pypi package requests has been the de-facto standard forever. Can it really be overthrown? Is this a classic case of “oh how the mighty have fallen”? I want to explore what the new httpx package has to offer, but mostly just …. which one is faster. That

The Architectural Foundation of Modern AI Pipelines Architecting enterprise Python AI integration pipelines requires a departure from the experimental

For example, how fast or slow is it to add an item to a list in Python? What about opening a file? Is that less than a millisecond? Is there something that makes that slower than you might have guessed? If you have a performance sensitive algorithm, which data structure should you use? How much memory does a floating point number use? What about a single character or the empty string? How fast is FastAPI compared to Django? I wanted to take a moment and write down performance numbers specifically focused o
