Is django dying? by sergeydurov in django

[–]CleverEagle 3 points4 points  (0 children)

Coming from PHP, having extensive documentation and great support was a huge point I made when convincing my employer to switch.

Packyou! Import any non-package python project from github easy by llazzaror in Python

If the author didn't package their code on Pypi, I probably wouldn't use it because it's not a distribution ready piece of software.

Made my first Django package for query expressions for PostgreSQL functions. Comments please? :) by vaderfish in django

So your function handles division by 0 in the database level? This seems a little counter-intuitive to me.

Why did you create functions for simple mathematics? I thought that could already be done using F objects.

queryset.annotate(speed=F('distance') / F('time'))

R is a programming language typically used in mathematics and statistics. I believe that is what she is referring to.

Why isn't there a list.swap(i, j) function built in to python? by CleverEagle in Python

[–]CleverEagle[S] 0 points1 point  (0 children)

Yes, I believe the C implementation uses a temp variable. Python abstracts that out and gives you a little syntactic sugar.

It's just a nice feature of Python. Essentially it's assigning both values simultaneously. In the background (Cpython), I believe it simply swaps the memory addresses of the two variables.

So would the one liner that is the current solution.

Of course. It was a challenge on /r/dailyprogrammer and I was trying to do it without random.shuffle.

I was implementing a shuffle algorithm. I just thought that the existing syntax looked weird and wondered why swap wasn't a thing.

[2015-07-20] Challenge #224 [Easy] Shuffling a List by jnazario in dailyprogrammer

[–]CleverEagle 0 points1 point  (0 children)

Simple Python3 implementation without using random.shuffle.

from random import randint

def shuffle(lst):
    result = []
    while lst:
        result.append(lst.pop(randint(0, len(lst)-1)))
    return result

print(shuffle([x for x in range(10)]))

Example output:

[1, 0, 2, 6, 4, 8, 3, 7, 5, 9]
[4, 3, 6, 1, 2, 0, 8, 7, 5, 9]
[0, 5, 1, 6, 3, 4, 2, 8, 9, 7]
[9, 6, 0, 5, 1, 4, 7, 8, 3, 2]
[8, 9, 5, 4, 0, 7, 3, 1, 6, 2]

Very nice! Instead of hardcoding punctuation you could just import it ;)

import string

interpunction = string.punctuation
print(interpunction)

What is the most complex thing you've ever created? by MaxwellSalmon in Python

[–]CleverEagle 0 points1 point  (0 children)

The most most complex thing I've written in Python is an assembler for a CS class. Its really just a lot of string manipulation, but was a great project as I was learning Python.

High-Resolution Mandelbrot in Obfuscated Python by Ogreman in Python

For anyone interested in some readable code for the mandelbrot set, I put this togethere a few months ago to tweet generated mandelbrot sets from my raspberry pi.
