Deleting multiple elements from a list
497,426
<p>Is it possible to delete multiple elements from a list at the same time? If I want to delete elements at index 0 and 2, and try something like del somelist[0], followed by del somelist[2], the second statement will actually delete somelist[3].</p> <p>I suppose I could always delete the higher numbered elements firs...

How do Django model fields work?
500,650
<p>First of all,I'm not into web programming. I bumped into django and read a bit about models. I was intrigued by the following code ( from djangoproject.com ) :</p> <pre><code> class Person(models.Model): first_name = models.CharField(max_length=50) last_name = models.CharField(max_length=50) def __str_...

<p>Yes, first_name and last_name are class variables. They define fields that will be created in a database table. There is a Person table that has first_name and last_name columns, so it makes sense for them to be at Class level at this point.</p> <p>For more on models, see: <a href="http://docs.djangoproject.com/en/...

<p>The essence of your question is "how come these class variables (which I assign Field objects to) suddenly become instance variables (which I assign data to) in Django's ORM"? The answer to that is the magic of Python <a href="http://docs.python.org/reference/datamodel.html">metaclasses</a>.</p> <p>A metaclass all...

<p>Yes, I could recommend you to use spawning over apache/wsgi setup.</p> <p>Two reasons basically: 1) Memory usage (you'll save some MBs on spawning) 2) Dynamic code reloading (at no point of time, your user's will see a 404 or 500 page)</p> <p>This comes from experience, I am running <a href="http://tunesdiary.com"...

<p>You can also perform case insensitive searches using search/match without the IGNORECASE flag (tested in Python 2.7.3):</p> <pre><code>re.search(r'(?i)test', 'TeSt').group() ## returns 'TeSt' re.match(r'(?i)test', 'TeSt').group() ## returns 'TeSt' </code></pre>
