Yes, but you have to OR them together:

```python
x = re.findall(pattern=r&#39;CAT.+?END&#39;, string=&#39;Cat \n eND&#39;, flags=re.I | re.DOTALL)
```

You can&#39;t put the flags within a tuple. Use the pipe character (OR operand) within your flags: 

    x = re.findall(r&#39;CAT.+?END&#39;,&#39;Cat \n eND&#39;,flags=re.I | re.DOTALL)

&gt;Is there a way to use more than one flag ?

It wasn&#39;t mentioned, but you can use [**inline `(?...)` modifiers**](http://www.rexegg.com/regex-disambiguation.html#modifiers) as well.

    x = re.findall(r&#39;(?si)CAT.+?END&#39;, &#39;Cat \n eND&#39;)

I used IntelliJ for &quot;Inspect Code&quot;, and one of its results is:

What does it mean, how can I fix it?

it whole class is like this:

    package com.xxxxxxxxxxx.app.xxxx;
    
    public class HeartBeat
    {
        private static final Logger LOG = LoggerFactory.getLogger( HeartBeat.class );
        private final File heartBeatFile;
    
    
        public HeartBeat( File heartBeatFile )
        {
            this.heartBeatFile = heartBeatFile;
        }
    
    
        public void beat()
        {
            try
            {
                FileUtils.writeStringToFile( heartBeatFile, String.valueOf( System.currentTimeMillis() ) );
            }
            catch( IOException e )
            {
                LOG.error( &quot;Error while writing heart beat log&quot;, e );
            }
        }
    }

I am using carbon but trying to get the first day of the month so I can run a report from the beginning of the month till the current day.

        $date = [
            &#39;start&#39; =&gt; new \Carbon\Carbon(&#39;last month&#39;),
            &#39;end&#39; =&gt; new \Carbon\Carbon(&#39;today&#39;)
        ];

The above code will show todays date back to same date in the previous month. But I want to get from the 1st to now.

Is there an easy way to do this like I am above? Cant find anything in the docs.

I am using python 2.7 in Ubuntu 14.04. I installed scikit-learn, numpy and matplotlib with these commands: 

    sudo apt-get install build-essential python-dev python-numpy \
    python-numpy-dev python-scipy libatlas-dev g++ python-matplotlib \
    ipython
But when I import these packages:

    
    from sklearn.cross_validation import train_test_split

It returns me this error:

    ImportError: No module named sklearn.cross_validation

It seems there are already quite some questions here about relative import in python 3, but after going through many of them I still didn&#39;t find the answer for my issue. 
so here is the question. 

I have a package shown below

    package/
       __init__.py
       A/
          __init__.py
          foo.py
       test_A/
          __init__.py
          test.py

and I have a single line in test.py:

    from ..A import foo

now, I am in the folder of `package`, and I run 

    python -m test_A.test

I got message

    &quot;ValueError: attempted relative import beyond top-level package&quot;

but if I am in the parent folder of `package`, e.g., I run:

    cd ..
    python -m package.test_A.test

everything is fine. 

**Now my question is:** 
when I am in the folder of `package`, and I run the module inside the test_A sub-package as `test_A.test`, based on my understanding, `..A` goes up only one level, which is still within the `package` folder, why it gives message saying `beyond top-level package`. What is exactly the reason that causes this error message?

I have a string that is to be sent over a network. I need to check the total bytes it is represented in.

`sys.getsizeof(string_name)` returns extra bytes. For example for `sys.getsizeof(&quot;a&quot;)` returns 22 , while one character is only represented in 1 byte in python. Is there some other method to find this ?

I want to store my users location using longitude and latitude, at the moment this comes from Google Maps, but I will be using GeoDango and some point to work out distances between to points also. 

However, my first confusion is which field in Django I should be using to store the longitude and latitude values? The information I&#39;m getting is conflicting. 


The official documentation uses a ``FloatField``
https://docs.djangoproject.com/en/dev/ref/contrib/gis/tutorial/#geographic-models

    lon = models.FloatField()
    lat = models.FloatField()

Where almost every answer on stackoverflow shows a ``DecimalField``

    long = models.DecimalField(max_digits=8, decimal_places=3)
    lat = models.DecimalField(max_digits=8, decimal_places=3)

So what should I be using?

How can I make [`@functools.lru_cache`][1] decorator ignore some of the function arguments with regard to caching key?

For example, I have a function that looks like this:

    def find_object(db_handle, query):
        # (omitted code)
        return result

If I apply `lru_cache` decorator just like that, `db_handle` will be included in the cache key. As a result, if I try to call the function with the same `query`, but different `db_handle`, it will be executed again, which I&#39;d like to avoid. I want `lru_cache` to consider `query` argument only.

Why this code prints `AAC` instead of expected ``A$`C``?

    console.log(&#39;ABC&#39;.replace(&#39;B&#39;, &#39;$`&#39;));

    AAC

And how to make it give the expected result?

What is the regular expression to search for `word` string that is not followed by the `@` symbol?

For example:

    mywordLLD         OK
    myword.dff        OK
    myword@ld         Exclude



Find &#39;word&#39; not followed by a certain character

I have a challenging problem to solve. I&#39;m working on a script which takes a regex as an input. This script then finds all matches for this regex in a document and wraps each match in its own &amp;lt;span&amp;gt; element. The hard part is that the text is a formatted html document, so my script needs to navigate through the DOM and apply the regex across multiple text nodes at once, while figuring out where it has to split text nodes if needed.

For example, with a regex that captures full sentences starting with a capital letter and ending with a period, this document:

    &lt;p&gt;
      &lt;b&gt;HTML&lt;/b&gt; is a language used to make &lt;b&gt;websites.&lt;/b&gt;
      It was developed by &lt;i&gt;CERN&lt;/i&gt; employees in the early 90s.
    &lt;p&gt;

Would be turned into this:

    &lt;p&gt;
      &lt;span&gt;&lt;b&gt;HTML&lt;/b&gt; is a language used to make &lt;b&gt;websites.&lt;/b&gt;&lt;/span&gt;
      &lt;span&gt;It was developed by &lt;i&gt;CERN&lt;/i&gt; employees in the early 90s.&lt;/span&gt;
    &lt;p&gt;

The script then returns the list of all created spans.

I already have some code which finds all the text nodes and stores them in a list along with their position across the whole document and their depth. You don&#39;t really need to understand that code to help me and its recursive structure can be a bit confusing. T**he first part I&#39;m not sure how to do is figure out which elements should be included within the span.**

    function SmartNode(node, depth, start) {
      this.node = node;
      this.depth = depth;
      this.start = start;
    }


    function findTextNodes(node, depth, start) {
      var list = [];
      var start = start || 0;
      depth = (typeof depth !== &quot;undefined&quot; ? depth : -1);
    
      if(node.nodeType === Node.TEXT_NODE) {
        list.push(new SmartNode(node, depth, start));
      } else {
        for(var i=0; i &lt; node.childNodes.length; ++i) {
          list = list.concat(findTextNodes(node.childNodes[i], depth+1, start));
          if(list.length) start += list[list.length-1].node.nodeValue.length;
        }
      }
    
      return list;
    }

I figure I&#39;ll make a string out of all the document, run the regex through it and use the list to find which nodes correspond to witch regex matches and then split the text nodes accordingly.

But an issue arrives when I have a document like this:

    &lt;p&gt;
      This program is &lt;a href=&quot;beta.html&quot;&gt;not stable yet. Do not use this in production yet.&lt;/a&gt;
    &lt;/p&gt;

There&#39;s a sentence which starts outside of the `&lt;a&gt;` tag but ends inside it. Now I don&#39;t want the script to split that link in two tags. In a more complex document, it could ruin the page if it did. The code could either wrap two sentences together:

    &lt;p&gt;
      &lt;span&gt;This program is &lt;a href=&quot;beta.html&quot;&gt;not stable yet. Do not use this in production yet.&lt;/a&gt;&lt;/span&gt;
    &lt;/p&gt;

Or just wrap each part in its own element:

    &lt;p&gt;
      &lt;span&gt;This program is &lt;/span&gt;
      &lt;a href=&quot;beta.html&quot;&gt;
        &lt;span&gt;not stable yet.&lt;/span&gt;
        &lt;span&gt;Do not use this in production yet.&lt;/span&gt;
      &lt;/a&gt;
    &lt;/p&gt;

There could be a parameter to specify what it should do. I&#39;m just not sure **how to figure out when an impossible cut is about to happen**, and how to recover from it.

**Another issue comes when I have whitespace inside a child element like this**:

    &lt;p&gt;This is a &lt;b&gt;sentence. &lt;/b&gt;&lt;/p&gt;

Technically, the regex match would end right after the period, before the end of the `&lt;b&gt;` tag. However, it would be much better to consider the space as part of the match and wrap it like this:

    &lt;p&gt;&lt;span&gt;This is a &lt;b&gt;sentence. &lt;/b&gt;&lt;/span&gt;&lt;/p&gt;

Than this:

    &lt;p&gt;&lt;span&gt;This is a &lt;/span&gt;&lt;b&gt;&lt;span&gt;sentence.&lt;/span&gt; &lt;/b&gt;&lt;/p&gt;

But that&#39;s a minor issue. After all, I could just allow extra white-space to be included within the regex.


I know this might sound like a &quot;do it for me&quot; question and its not the kind of quick question we see on SO on a daily basis, but I&#39;ve been stuck on this for a while and it&#39;s for an open-source library I&#39;m working on. Solving this problem is the last obstacle. If you think another SE site is best suited for this question, redirect me please.

In Atom, If I activate regex mode on the search-and-replace tool, it can find newlines as `\n`, but when I try to replace them, they&#39;re still there.

I want to replace dots in `&quot;2014.06.09&quot;` to `&quot;2014-06-09&quot;`. I am using *gsub()* function for it. If 

    x &lt;-  &quot;2014.06.09&quot;
    gsub(&#39;2&#39;, &#39;-&#39; ,x)
    # [1] &quot;-014.06.09&quot;

But when I try 

    gsub(&#39;.&#39;, &#39;-&#39;, x)
    # [1] &quot;----------&quot;

instead of `&quot;2014-06-09&quot;`.

    class(x)
    # &quot;character&quot;

Can some suggest me a way to get this right and also why it is not working for `&#39;.&#39;` (dot)
