Can a decorator of an instance method access the class?
...s in a very simple way. The doc states that __set_name__ is "called at the time the owning class owner is created".
Here is an example:
class class_decorator:
def __init__(self, fn):
self.fn = fn
def __set_name__(self, owner, name):
# do something with owner, i.e.

Declaring variables inside loops, good practice or bad practice?
...value between each loop. In such case, you may need to initialize it every time. You can also create a larger block, encompassing the loop, whose sole purpose is to declare variables which must retain their value from one loop to another. This typically includes the loop counter itself.

...ing your source code, whether you know it or not.
Attackers control the runtime memory of the Flash interpreter, so that anyone who knows how to use a programmable debugger can alter any variable (including the current score) at any time, or alter the program itself.
The simplest possible attack a...
C: differences between char pointer and array [duplicate]
...ubtle difference. Essentially, the former:
char amessage[] = "now is the time";
Defines an array whose members live in the current scope's stack space, whereas:
char *pmessage = "now is the time";
Defines a pointer that lives in the current scope's stack space, but that references memory else...
Find nearest value in numpy array
...rray then the bisection code (given below) performs the fastest. ~100-1000 times faster for large arrays, and ~2-100 times faster for small arrays. It does not require numpy either.
If you have an unsorted array then if array is large, one should consider first using an O(n logn) sort and then bise...
Are there any worse sorting algorithms than Bogosort (a.k.a Monkey Sort)? [closed]
My co-workers took me back in time to my University days with a discussion of sorting algorithms this morning. We reminisced about our favorites like StupidSort , and one of us was sure we had seen a sort algorithm that was O(n!) . That got me started looking around for the "worst" sorting algor...
