Customized command line parsing in Python | 156,873 | <p>I'm writing a shell for a project of mine, which by design parses commands that looks like this:</p>
<p>COMMAND_NAME ARG1="Long Value" ARG2=123 ARG3=me@me.com</p>
<p>My problem is that Python's command line parsing libraries (getopt and optparse) forces me to use '-' or '--' in front of the arguments. This behavio... | 7 | 2008-10-01T09:35:36Z | 1,760,133 | <p>What about optmatch (<a href="http://www.coderazzi.net/python/optmatch/index.htm" rel="nofollow">http://www.coderazzi.net/python/optmatch/index.htm</a>)? Is not standard, but takes a different approach to options parsing, and it supports any prefix:</p>
<p>OptionMatcher.setMode(optionPrefix='-')</p>

<p>Here's a little nice library should your version of Python need it code.google.com/p/argparse</p>
<p>Enjoy.</p>

.order_by() isn't working how it should / how I expect it to | 156,951 | <p>In my Django project I am using <code>Product.objects.all().order_by('order')</code> in a view, but it doesn't seem to be working properly.</p>
<p>This is it's output:</p>
Product Name
Sort

... | 1 | 2008-10-01T10:09:42Z | 157,023 | <p>Your saving loop is wrong. You save Product outside of the loop. It should be:</p>
<pre><code>if request.method == 'POST':
PostEntries = len(request.POST)
x = 1
while x < PostEntries:
p = Product.objects.get(pk=x)
p.order = int(request.POST.get(str(x),''))

Most pythonic way of counting matching elements in something iterable | 157,039 | <p>I have an iterable of entries on which I would like to gather some simple statistics, say the count of all numbers divisible by two and the count of all numbers divisible by three.</p>
