[`url_for`][1] takes an `_external` keyword argument that will return an absolute (rather than relative) URL.  I believe you will need to set a `SERVER_NAME` config key with your root domain to make it work correctly.

In my app, I use a `UITableView` 
My problem is that I want to remove the last border of the last cell in `UITableView`.

How to remove the last border of the last cell in UITableView?

I am trying to prevent an AlertDialog box from closing when pressing the back button in Android. I have followed both of the popular methods [in this thread][1], and with System.out.println I can see that in both cases the code executes. However, the back button *still* closes the dialog box.

What could I be doing wrong? Ultimately I&#39;m trying to prevent the back button closing a dialog box - it is a disclaimer that is displayed the first time the app is run and I don&#39;t want the user to have any option but to press the &quot;Accept&quot; button in order for the app to continue.

When I call `url_for(&#39;index&#39;)` it will generate `&#39;/&#39;` but there are times where I&#39;d like it to generate `&#39;domain.tld/&#39;` instead. I can&#39;t find in the documentation where I would specify this. Do I just need to do `&#39;domain.tld/%s&#39; % url_for(&#39;index&#39;)`?

Where do I define the domain to be used by url_for() in Flask?

<p>When I call <code>url_for('index')</code> it will generate <code>'/'</code> but there are times where I'd like it to generate <code>'domain.tld/'</code> instead.

I understand that sets in Python are unordered, but I&#39;m curious about the &#39;order&#39; they&#39;re displayed in, as it seems to be consistent. They seem to be out-of-order in the same way every time:

    &gt;&gt;&gt; set_1 = set([5, 2, 7, 2, 1, 88])
    &gt;&gt;&gt; set_2 = set([5, 2, 7, 2, 1, 88])
    &gt;&gt;&gt; set_1
    set([88, 1, 2, 5, 7])
    &gt;&gt;&gt; set_2
    set([88, 1, 2, 5, 7])

...and another example:

    &gt;&gt;&gt; set_3 = set(&#39;abracadabra&#39;)
    &gt;&gt;&gt; set_4 = set(&#39;abracadabra&#39;)
    &gt;&gt;&gt; set_3
    set([&#39;a&#39;, &#39;r&#39;, &#39;b&#39;, &#39;c&#39;, &#39;d&#39;])
    &gt;&gt;&gt;&gt; set_4
    set([&#39;a&#39;, &#39;r&#39;, &#39;b&#39;, &#39;c&#39;, &#39;d&#39;])

I&#39;m just curious why this would be. Any help?

I have a model something like this:

```python
class Task(models.Model):
    progress = models.PositiveIntegerField()
    estimated_days = models.PositiveIntegerField()
```

Now I would like to do a calculation `Sum(progress * estimated_days)` on the database level. Using Django Aggregation I can have the sum for each field but not the summation of multiplication of fields.

The index that I have in the dataframe (with 30 rows) is of the form:

    Int64Index([171, 174,173, 172, 199..............
            ....175, 200])

The index is not strictly increasing because the data frame is the output of a sort().
I want to have add a column which is the series:
    
    [1, 2, 3, 4, 5......................., 30]

How should I go about doing that?

Since Python&#39;s `string` can&#39;t be changed, I was wondering how to concatenate a string more efficiently?

I can write like it:

```py
s += stringfromelsewhere
```

or like this:

```py
s = []

s.append(somestring)
    
# later
    
s = &#39;&#39;.join(s)
```

While writing this question, I found a good article talking about the topic.

http://www.skymind.com/~ocrow/python_string/

But it&#39;s in Python 2.x., so the question would be did something change in Python 3?

Which is the preferred way to concatenate a string in Python?

I&#39;m just starting to learn Flask, and I am trying to create a form which will allow a **POST** method.

Here&#39;s my method:

    @app.route(&#39;/template&#39;, methods=[&#39;GET&#39;, &#39;POST&#39;])
    def template():
        if request.method == &#39;POST&#39;:
            return(&quot;Hello&quot;)
        return render_template(&#39;index.html&#39;)

And my `index.html`:

&lt;!-- language: lang-html --&gt;

    &lt;html&gt;

    &lt;head&gt;
      &lt;title&gt; Title &lt;/title&gt;
    &lt;/head&gt;

    &lt;body&gt;
      Enter Python to execute:
      &lt;form action=&quot;/&quot; method=&quot;post&quot;&gt;
        &lt;input type=&quot;text&quot; name=&quot;expression&quot; /&gt;
        &lt;input type=&quot;submit&quot; value=&quot;Execute&quot; /&gt;
      &lt;/form&gt;
    &lt;/body&gt;

    &lt;/html&gt;

Loading the form (rendering it when it receives **GET**) works fine. When I click on the **submit** button however, I get a `POST 405 error Method Not Allowed`.

Why isn&#39;t it displaying **&quot;Hello&quot;**?

I am trying to build a small site with the server push functionality on Flask micro-web framework, but I did not know if there is a framework to work with directly. 

I used [Juggernaut][1], but it seems to be not working with [redis-py][2] in current version, and Juggernaut has been deprecated recently.

Does anyone has a suggestion with my case?
