One week it’s a user name that includes a middle dot, the next it’s a CSV file with non‑breaking spaces, and the next it’s a

A deep dive into how Python passes arguments and mutability to prevent unexpected bugs

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

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
