The particular format for `strptime`:

    datetime.datetime.strptime(string_date, &quot;%Y-%m-%d %H:%M:%S.%f&quot;)
    #&gt;&gt;&gt; datetime.datetime(2013, 9, 28, 20, 30, 55, 782000)

You should use [`datetime.datetime.strptime`][0]:


    import datetime

    dt = datetime.datetime.strptime(string_date, fmt)

`fmt` will need to be the appropriate format for your string. You&#39;ll find the [reference on how to build your format here][1].

I am using Xcode 5&#39;s Asset Catalog, and I would like to use my `LaunchImage` as the background image of my home view (a pretty common practice to make the transition from &#39;loading&#39; to &#39;loaded&#39; look smooth).

I would like to use the same entry in the Asset Catalog to save space and not have to replicate the image in two different Image Sets.

However, calling:

    UIImage *image = [UIImage imageNamed:@&quot;LaunchImage&quot;]; //returns nil

In ipython Notebook, first create a pandas Series object, then by calling the instance method .hist(), the browser displays the figure. 

I am wondering how to save this figure to a file (I mean not by right click and save as, but the commands needed in the script).

I have two vectors of data and I&#39;ve put them into `pyplot.scatter()`. Now I&#39;d like to over plot a linear fit to these data. How would I do this? I&#39;ve tried using `scikitlearn` and `np.polyfit()`.

I have a request URI and a token. If I use:

    curl -s &quot;&lt;MY_URI&gt;&quot; -H &quot;Authorization: TOK:&lt;MY_TOKEN&gt;&quot;

etc., I get a 200 and view the corresponding JSON data.
So, I installed requests and when I attempt to access this resource I get a 403 probably because I do not know the correct syntax to pass that token. Can anyone help me figure it out?
This is what I have:

    import sys,socket
    import requests

    r = requests.get(&#39;&lt;MY_URI&gt;&#39;,&#39;&lt;MY_TOKEN&gt;&#39;)
    r. status_code

I already tried:

    r = requests.get(&#39;&lt;MY_URI&gt;&#39;,auth=(&#39;&lt;MY_TOKEN&gt;&#39;))
    r = requests.get(&#39;&lt;MY_URI&gt;&#39;,auth=(&#39;TOK&#39;,&#39;&lt;MY_TOKEN&gt;&#39;))
    r = requests.get(&#39;&lt;MY_URI&gt;&#39;,headers=(&#39;Authorization: TOK:&lt;MY_TOKEN&gt;&#39;))

But none of these work.

I am on ubuntu 13.04, bash, python2.7.4

**The interpreter doesn&#39;t see variables I set.**

Here is an example:

    $ echo $A
    5
    $ python -c &#39;import os; print os.getenv( &quot;A&quot; )&#39;
    None
    $ python -c &#39;import os; print os.environ[ &quot;A&quot; ]&#39;
    Traceback (most recent call last):
      File &quot;&lt;string&gt;&quot;, line 1, in &lt;module&gt;
      File &quot;/usr/lib/python2.7/UserDict.py&quot;, line 23, in __getitem__
        raise KeyError(key)
    KeyError: &#39;A&#39;

But everything works fine with the `PATH` variable:

    $ echo $PATH 
    /usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games
    $ python -c &#39;import os; print os.getenv(&quot;PATH&quot;)&#39;
    /usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

And it notices changes in `PATH`:

    $ PATH=&quot;/home/alex/tests/:$PATH&quot;
    $ echo $PATH 
    /home/alex/tests/:/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games
    $ python -c &#39;import os; print os.getenv(&quot;PATH&quot;)&#39;
    /home/alex/tests/:/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

What could be wrong?

PS  the problem comes when using `$PYTHONPATH`:

    $ python -c &#39;import os; print os.getenv(&quot;PYTHONPATH&quot;)&#39;
    None


python - os.getenv and os.environ don&#39;t see environment variables of my bash shell

How can I get the current date in MS-SQL Server 2008 R2?

The format of the column in my database is `DATETIME` and dates are stored in the following format:

    +++++++++++++ Vrdate ++++++++++
    |                             |
    |   2012-11-18 00:00:00.000   |
    |   2012-11-19 00:00:00.000   |
    |   2013-11-18 00:00:00.000   |
    |   2012-12-01 00:00:00.000   |
    |   2010-10-09 00:00:00.000   |
    |   2012-11-11 00:00:00.000   |
    |                             |
    +++++++++++++++++++++++++++++++

I searched but wasn&#39;t able to find the way to get the date in this format (i.e. which has the time associated with it in `00:00:00.00`). I found `GETDATE()` function but that provides the current time along with the date as well, what I want is get the date in the following format: `CurrentDate 00:00:00.00`

How may I get this?

Getting the current date in SQL Server?

Is there a value or command like DATETIME that I can use in a manual query to insert the current date and time? 

    INSERT INTO servers (

    ) VALUES(

The quoted DATETIME value at the end is where I want to add the current date and time.

How to get current date &amp; time in MySQL?

I&#39;m receiving a date string from an API, and it is formatted as `yyyy-mm-dd`.

I am currently using a regex to validate the string format, which works ok, but I can see some cases where it could be a correct format according to the string but actually an invalid date. i.e. `2013-13-01`, for example.

Is there a better way in PHP to take a string such as `2013-13-01` and tell if it is a valid date or not for the format `yyyy-mm-dd`?



Correctly determine if date string is a valid date in that format

I am trying to convert `DateTime` format to `yyyy-MM-dd` format and store it to `DateTime` object. But it gives me the System `DateTime` format that is `MM/dd/yyyy`.  
I am using following code to convert.  

    string dateTime = DateTime.Now.ToString();
    string createddate = Convert.ToDateTime(dateTime).ToString(&quot;yyyy-MM-dd h:mm tt&quot;);         
    DateTime dt = DateTime.ParseExact(createddate, &quot;yyyy-MM-dd h:mm tt&quot;,CultureInfo.InvariantCulture);
    
            
but non of the above line converts into the specified format.  
Can any one help to solve this.

I am getting the DateTime from one application and passing this object to other application and That application is storing that date into MySql&#39;s DateTime field which is in the format &quot;yyyy-MM-dd&quot;.  
This is why I have posted this question.  

Project 1 has class from that I am getting the date.
and the processor class which is the middle ware of the application it processes the DateTime format to convert in specific format. And passes to the Other project which consumes the DateTime and stores that in the MySql field.
