I think you want something like

`Settings | Editor | General | Smart Keys` -&gt; `Surround selection on typing quote or brace`

PyCharm 4.0 has the option to `Surround With...`, by selecting your code snippet and [pressing][1] 

&lt;kbd&gt;ctrl&lt;/kbd&gt; + &lt;kbd&gt;alt&lt;/kbd&gt; + &lt;kbd&gt;T&lt;/kbd&gt;

or on Mac: &lt;kbd&gt;⌥&lt;/kbd&gt; + &lt;kbd&gt;⌘&lt;/kbd&gt; + &lt;kbd&gt;T&lt;/kbd&gt;

Option 1 should provide you with the functionality you are looking for:

So I have this app called Dripper that I put out about a month ago and then an update a couple days ago. The update added push notifications and a few little tweaks. I tested it with the sandbox-apn using the development profile and things worked great. Then I switched things to the production-apn and pushed it to test-flight, again things worked perfectly. Once I put update on the market and ran it I noticed I wasn’t getting any new push registrations on the server. I looked at the console logs for the device and found this:

&gt;Dec  4 17:55:15 Ina-touch-it coffco[1210] &lt;Warning&gt;: Registering for remote notifications&lt;br/&gt;

I have `users` table in my MySql database. This table has `id`, `name` and `age` fields.

How can I delete some record by `id`?

Now I use the following code:

    user = User.query.get(id)
    db.session.delete(user)
    db.session.commit()

But I don&#39;t want to make any query before delete operation. Is there any way to do this? I know, I can use `db.engine.execute(&quot;delete from users where id=...&quot;)`, but I would like to use `delete()` method.

How to iterate over arguments

&gt; **TL;DR**: I need a way to decode a QR-code from an image file using (preferable pure) Python.

I&#39;ve got a jpg file with a QR-code which I want to decode using Python. I&#39;ve found a couple libraries which claim to do this:

**PyQRCode** ([website here][1]) which supposedly can decode qr codes from images by simply providing a path like this:

    import sys, qrcode
    d = qrcode.Decoder()
    if d.decode(&#39;out.png&#39;):
        print &#39;result: &#39; + d.result
    else:
        print &#39;error: &#39; + d.error

So I simply installed it using `sudo pip install pyqrcode`. The thing I find strange about the example code above however, is that it only imports `qrcode` (and not `pyqrcode` though) Since I think `qrcode` refers to [this library][2] which can only *generate* qr-code images it kind of confused me. So I tried the code above with both `pyqrcode` and `qrcode`, but both fail at the second line saying `AttributeError: &#39;module&#39; object has no attribute &#39;Decoder&#39;`. Furthermore, [the website][1] refers to Ubuntu 8.10 (which came out more than 6 years ago) and I can&#39;t find a public (git or other) repository of it to check the latest commit. So I moved on to the next library:


**ZBar** ([website here][3]) claims to be `&quot;an open source software suite for reading bar codes from various sources, such as image files.&quot;` So I tried installing it on Mac OSX running `sudo pip install zbar`. This fails with `error: command &#39;cc&#39; failed with exit status 1`. I tried to suggestions in the answers to [this SO question][4], but I can&#39;t seem to solve it. So I decided to move on again:

**QRTools**, which according to [this blogpost][5] can decode images easily by using the following code:

    from qrtools import QR
    myCode = QR(filename=u&quot;/home/psutton/Documents/Python/qrcodes/qrcode.png&quot;)
    if myCode.decode():
      print myCode.data
      print myCode.data_type
      print myCode.data_to_string()

So I tried installing it using `sudo pip install qrtools`, which can&#39;t find anything. I also tried it with `python-qrtools`, `qr-tools`, `python-qrtools` and a couple more combinations, but unfortunately to no avail. I suppose it refers to [this repo][6] which says it is based on ZBar (see above). Although I want to run my code on Heroku (and thus prefer a pure Python solution) I successfully installed it on a Linux box (with `sudo apt-get install python-qrtools`) and tried running it:

    from qrtools import QR
    c = QR(filename=&#39;/home/kramer65/qrcode.jpg&#39;)
    c.data  # prints u&#39;NULL&#39;
    c.data_type  # prints u&#39;text&#39;
    c.data_to_string()  # prints &#39;\xef\xbb\xbfNULL&#39; where I expect an int (being `1234567890`)


Although this seems to decode it, It doesn&#39;t seem to do it correctly. It furthermore needs ZBar and is thus not pure Python. So I decided to find yet another library.

**PyXing** ([website here][7]) is supposedly a Python port of the popular Java [ZXing library][8], but the initial and only commit is 6 years old and the project has no readme or documentation whatsoever.

For the rest I found a couple qr-**en**coders (not **de**coders) and some API endpoints which can decode for you. Since I don&#39;t like this service to be dependent on other API endpoints I would want to keep the decoding local though.

So to conclude; would anybody know how I can decode QR-codes from images in (preferable pure) Python? All tips are welcome!

I am getting a `ValueError: cannot reindex from a duplicate axis` when I am trying to set an index to a certain value. I tried to reproduce this with a simple example, but I could not do it.

Here is my session inside of `ipdb` trace. I have a DataFrame with string index, and integer columns, float values. However when I try to create `sum` index for sum of all columns I am getting `ValueError: cannot reindex from a duplicate axis` error. I created a small DataFrame with the same characteristics, but was not able to reproduce the problem, what could I be missing?

I don&#39;t really understand what `ValueError: cannot reindex from a duplicate axis`means, what does this error message mean? Maybe this will help me diagnose the problem, and this is most answerable part of my question.

What does `ValueError: cannot reindex from a duplicate axis` mean?

Can someone point me to a link or provide an explanation of the benefits of indexing in pandas? I routinely deal with tables and join them based on columns, and this joining/merging process seems to re-index things anyway, so it&#39;s a bit cumbersome to apply index criteria considering I don&#39;t think I need to.

Any thoughts on best-practices around indexing?

I&#39;m working with Rails and PostgreSQL and have a basic one-to-many relationship going on, one `Auction` has many `Bid`s. However when I try and delete an auction (that has bids present) I get the following error: 

&gt; ERROR: update or delete on table &quot;auctions&quot; violates foreign key
&gt; constraint &quot;fk_rails_43e9021cbf&quot; on table &quot;bids&quot;. DETAIL: Key(id)=(1)
&gt; is still referenced from table &quot;bids&quot;.

Deleting auctions with no bids gives no error.

The part that confuses me is that inside my `Auction` model, I have:

    has_many :bids, dependent: :destroy

![Error Screen Shot (better_error gem)][1]

Since I have a dependent destroy clause, why am I still getting this error?

For a plugin for Sublime Text I was required to install a composer package globally.

In order to do this I had to run the following command:

    composer global require &quot;asm89/twig-lint&quot; &quot;@stable&quot;

The installation started running and a few seconds later the package was installed. Voila! Well, not really.

Step two was to add some lines to my Sublime Text configuration file:

    {
        &quot;user&quot;: {
            &quot;paths&quot;: {
                &quot;windows&quot;: [&quot;C:\\Users\\yourname\\.composer\\vendor\\bin&quot;]
            },
        }
    }

However, the plugin is not working. So I decided to check the path. And it appears there is no `.composer` directory in my profile directory. It isn&#39;t in my `php` directory either. And I can&#39;t find it anywhere.

I would like to know if there&#39;s a way to locate this directory and would appreciate any suggestions that can help me get this plugin to work.

I&#39;m getting the following errors in Pycharm.
&gt;Error: Django is not importable in this environment


It used to work well but I moved the project and virtualenv to other directory and the error appeared. It&#39;s weird because if I run the project ignoring the configuration settings warning that I get, works fine. 

The problem is that now, Pycharm is not finding the project interperter.

The command that Pycharm is running is:
 
    /Users/plorenzo/../gestorSchools/venv/bin/python3.4 /Users/plorenzo/../gestorSchools/schoolsManager/manage.py runserver 8000

The virtualenv is activated.

My $PATH is:

and my $PYTHONPATH:

    /Library/Frameworks/Python.framework/Versions/3.4/bin/python3.4


I spent a few days trying to find the solution but I couldn&#39;t find it.


Pycharm error Django is not importable in this environment

I have been using PyCharm for a bit so I am not an expert. 

How I normally ran my programs was with the terminal like so:

`program.py -t input1 -t1 input2`

I was wondering how can I debug this? 

For other programs I wrote, I did not have any arguments so debugging was simply setting break points and pressing debug.

I&#39;ve got Pycharm 4 running on my Linux (Ubuntu 14.04) machine.  In addition to the system python, I&#39;ve also got Anaconda installed.  Getting the two to play nicely together seems to be a bit of a problem... PyCharm provides some interesting integration for `virtualenv`s and `pip`, but the Anaconda Python distribution seems to prefer using its own `conda` tool for both activities.

Is there a relatively simple/painless way to be able to use `conda` in conjunction with PyCharm?  Not just as an alternative interpreter i.e. point PyCharm at the Anaconda Python binary for a project interpreter, but to be able to create, source/activate and deactivate virtual envs, add/remove packages in those virtual envs, etc. 

Or am I going to have to choose between using Anaconda (and having a more recent and up-to-date python than may come with the system), and being able to use PyCharm&#39;s features to their fullest extent?
