Use the strings [join-method](https://docs.python.org/3/library/stdtypes.html#str.join).

    print(&#39; &#39;.join([&#39;word1&#39;, &#39;word2&#39;, &#39;word3&#39;]))

You can join any iterable (not only the `list` used here) and of course you can use any string (not only `&#39; &#39;`) as the delimiter.


If you want a random order like you said in your question use [shuffle](http://docs.python.org/library/random.html#random.shuffle).

In the comment there was the question why Python throws an error if you do `&quot;glue&quot;.join([&quot;startString&quot;, 123, &quot;endString&quot;])`. `join` operates on an iterable of strings. There is no implicit type conversion in Python.

But of course there is a solution. Just do the conversion yourself.

`&quot;glue&quot;.join(map(str, [&quot;startString&quot;,123,&quot;endString&quot;]))`

Okay I&#39;ve just found a function that does what I wanted to do;

I read in a file with words in a format like: 
`Jack/Jill/my/kill/name/bucket`

I then split it up using the `split()` method and once I had the word into an list, I concatenated the words with this method: 

    concatenatedString = &#39; - &#39;.join(myWordList)
    # ie: delimeter.join(list)

I am getting an ORA-01000 SQL exception. So I have some queries related to it.

1. Are maximum open cursors exactly related to number of JDBC connections, or are they also related to the statement and resultset objects we have created for a single connection ? (We are using pool of connections)
2. Is there a way to configure the number of statement/resultset objects in the database (like connections) ?
3. Is it advisable to use instance variable statement/resultset object instead of method local statement/resultset object in a single threaded environment ?
4. Does executing a prepared statement in a loop cause this issue ? (Of course, I could have used sqlBatch) Note: pStmt is closed once loop is over.

        { //method try starts  
          String sql = &quot;INSERT into TblName (col1, col2) VALUES(?, ?)&quot;;
          pStmt = obj.getConnection().prepareStatement(sql);
          pStmt.setLong(1, subscriberID);
          for (String language : additionalLangs) {
            pStmt.setInt(2, Integer.parseInt(language));
            pStmt.execute();
          }
        } //method/try ends

        { //finally starts
           pStmt.close()
        } //finally ends 

5. What will happen if conn.createStatement() and conn.prepareStatement(sql) are called multiple times on single connection object ?

&lt;B&gt;Edit1: &lt;/B&gt;
6. Will the use of Weak/Soft reference statement object help in preventing the leakage ? 

&lt;B&gt;Edit2: &lt;/B&gt;
 1. Is there any way, I can find all the missing &quot;statement.close()&quot;s in my project ? I understand it is not a memory leak. But I need to find a statement reference (where close() is not performed) eligible for garbage collection ? Any tool available ? Or do I have to analyze it manually ?

Please help me understand it.

In Chrome for Mac, one can &quot;overscroll&quot; a page (for lack of a better word), as shown in the screenshot below, to see &quot;what&#39;s behind&quot;, similar to the iPad or iPhone.

I&#39;ve noticed that some pages have it disabled, like gmail and the &quot;new tab&quot; page.

How can I disable &quot;overscrolling&quot;? Are there other ways in which I can control &quot;overscrolling&quot;?

This question started out with me not understanding why I couldn&#39;t pass variables to a symfony2 global helper function (service), but thanks to people brighter than I, I realized my error was about trying to use the security_context from within a class that didn&#39;t have it injected so...

This is the final result, the code that works. I found no better way of making this helpful to the comunity.

This is how you can get the user and other data from security_context from within a global function or helper function in symfony2.

I have the following class and function:

    &lt;?php
    namespace BizTV\CommonBundle\Helper;
    
    use Symfony\Component\DependencyInjection\ContainerInterface as Container;
    
    class globalHelper {    
    
    private $container;
    
    public function __construct(Container $container) {
        $this-&gt;container = $container;
    }   

        //This is a helper function that checks the permission on a single container
        public function hasAccess($container)
        {
            $user = $this-&gt;container-&gt;get(&#39;security.context&#39;)-&gt;getToken()-&gt;getUser();
            
            //do my stuff
        }     
    }

...defined as a service (in app/config/config.yml) like this...

    #Registering my global helper functions            
    services:
      biztv.helper.globalHelper:
        class: BizTV\CommonBundle\Helper\globalHelper
        arguments: [&#39;@service_container&#39;]

Now, in my controller I call on this function like this...

    public function createAction($id) {
        
        //do some stuff, transform $id into $entity of my type...

        //Check if that container is within the company, and if user has access to it.
        $helper = $this-&gt;get(&#39;biztv.helper.globalHelper&#39;);
        $access = $helper-&gt;hasAccess($entity);

I&#39;ve read the [global installation documentation][1] for Composer, but it&#39;s for *nix systems only:

&lt;!-- language-all: lang-none --&gt;


    curl -s https://getcomposer.org/installer | php
    sudo mv composer.phar /usr/local/bin/composer

I would be such happy doing the same on Windows, that&#39;s the OS of my development machine. I would be able to run

    composer update

From an arbitrary folder where `composer.json` exists. Interpreter `php.exe` is already in `PATH` variable.

Any clue?

I want to create a single executable from my Python project.  A user should be able to download and run it without needing Python installed.  If I were just distributing a package, I could use pip, wheel, and PyPI to build and distribute it, but this requires that the user has Python and knows how to install packages.  What can I use to build a self-contained executable from a Python project?

I have a Python pandas DataFrame `rpt`:

    rpt
    &lt;class &#39;pandas.core.frame.DataFrame&#39;&gt;
    MultiIndex: 47518 entries, (&#39;000002&#39;, &#39;20120331&#39;) to (&#39;603366&#39;, &#39;20091231&#39;)
    Data columns:
    STK_ID                    47518  non-null values
    STK_Name                  47518  non-null values
    RPT_Date                  47518  non-null values
    sales                     47518  non-null values

I can filter the rows whose stock id is `&#39;600809&#39;` like this: `rpt[rpt[&#39;STK_ID&#39;] == &#39;600809&#39;]`

    &lt;class &#39;pandas.core.frame.DataFrame&#39;&gt;
    MultiIndex: 25 entries, (&#39;600809&#39;, &#39;20120331&#39;) to (&#39;600809&#39;, &#39;20060331&#39;)
    Data columns:
    STK_ID                    25  non-null values
    STK_Name                  25  non-null values
    RPT_Date                  25  non-null values
    sales                     25  non-null values


and I want to get all the rows of some stocks together, such as `[&#39;600809&#39;,&#39;600141&#39;,&#39;600329&#39;]`. That means I want a syntax like this: 

    stk_list = [&#39;600809&#39;,&#39;600141&#39;,&#39;600329&#39;]
    
    rst = rpt[rpt[&#39;STK_ID&#39;] in stk_list] # this does not works in pandas 

Since pandas not accept above command, how to achieve the target?

I&#39;m using [strptime](http://docs.python.org/library/datetime.html#datetime.datetime.strptime) to convert a date string into a `datetime`. According to the linked page, formatting like this should work:

    &gt;&gt;&gt; # Using datetime.strptime()
    &gt;&gt;&gt; dt = datetime.strptime(&quot;21/11/06 16:30&quot;, &quot;%d/%m/%y %H:%M&quot;)

My code is:

    import datetime
    dtDate = datetime.strptime(sDate,&quot;%m/%d/%Y&quot;)

where `sDate = &quot;07/27/2012&quot;`. (I understand, from the same page, that `%Y` is *&quot;Year with century as a decimal number.&quot;*)

I have tried putting the actual value of sDate into the code:

    dtDate = datetime.strptime(&quot;07/27/2012&quot;,&quot;%m/%d/%Y&quot;)

but this does not work. The error I get is:

&gt; AttributeError: &#39;module&#39; object has no attribute &#39;strptime&#39;

What am I doing wrong?

Why is datetime.strptime not working in this simple example?

I&#39;m a novice at PHP and I need a quick solution to the following problem but can&#39;t seem to come up with one:

I have a multi-dimensional array like so

    Array
    (
        [0] =&gt; Array
            (
                [blogTags_id] =&gt; 1
                [tag_name] =&gt; google
                [inserted_on] =&gt; 2013-05-22 09:51:34
                [inserted_by] =&gt; 2
            )
    
        [1] =&gt; Array
            (
                [blogTags_id] =&gt; 2
                [tag_name] =&gt; technology
                [inserted_on] =&gt; 2013-05-22 09:51:34
                [inserted_by] =&gt; 2
            )
    )

I want to use the `implode()` to somehow return a comma-separated string containing values of `tag_name` key like so. 

    google, technology

Is it possible to achieve this effect with the said function? If not then please suggest an alternate solution.
