    re.compile(&quot;Sent from my (iPhone|iPod)&quot;)

    re.compile(&quot;Sent from my (?:iPhone|iPod)&quot;)

If you need to capture matches, remove the `?:`.

Fyi, your regex didn&#39;t work because you are testing for one character out of i,P,h,o,n,e or one character out of i,P,o,d..



What&#39;s the simplest one-liner to get the last commit date for a bunch of files in a Git repository (i.e., for each file, the date of the last commit that changed that file)?

The context for this is that I&#39;m using other Bash commands to find a long list of files matching some criteria, and I&#39;d like to just pipe this list into a Git command to get the last commit date for each file.

Im sorry to ask this question again. I have searched and found endles repeats of it both on stackoverflow and also on general google search. Unfortunatly I just cant get my system sorted.

I have the following:

    C:\Python27\Lib\site-packages\wx-2.8-msw-unicode

this folder contains the wx folder and also wx &amp; wxPython folders which each contain the 
`_init_.py` files

When I import wx I get the error message `&quot;no module named wx&quot;`

What do I need to do in order to get Python to find the relevant files to allow me to &quot;import wx&quot; succesfully


Python ImportError: No module named wx

I have a model

    class ItemPrice( models.Model ):
         price = models.DecimalField ( max_digits = 8, decimal_places=2 )
         ....

I tried this to calculate the sum of `price` in this queryset:

    items = ItemPrice.objects.all().annotate(Sum(&#39;price&#39;))

what&#39;s wrong in this query? or is there any other way to calculate the Sum of `price` column? 

I know this can be done by using for loop on queryset but i need an elegant solution.

Thanks!

Django: Calculate the Sum of the column values through query

Let&#39;s say I have the following models

    class Photo(models.Model):
        tags = models.ManyToManyField(Tag)

    class Tag(models.Model):
        name = models.CharField(max_length=50)

In a view I have a list with active filters called *categories*.
I want to filter Photo objects which have all tags present in *categories*. 

I tried:

    Photo.objects.filter(tags__name__in=categories)
But this matches *any* item in categories, not *all* items.

So if categories would be [&#39;holiday&#39;, &#39;summer&#39;] I want Photo&#39;s with both a holiday and summer tag.

Can this be achieved?

I have four strings and any of them can be empty. I need to join them into one string with spaces between them. If I use:

    new_string = string1 + &#39; &#39; + string2 + &#39; &#39; + string3 + &#39; &#39; + string4

The result is a blank space on the beginning of the new string if `string1` is empty. Also, I have three blank spaces if `string2` and `string3` are empty. 

How can I easily join them without blank spaces when I don&#39;t need them?

Is there a way to URL decode a string in Python 3

to take something like this 

    id%253D184ff84d27c3613d%26quality%3Dmedium

and decode it twice to get

    id=184ff84d27c3613d&amp;quality=medium

I have a character string and what to extract the information inside of multiple parentheses.  Currently I can extract the information from the last parenthesis with the code below.  How would I do it so it extracts multiple parentheses and returns as a vector? 

    j &lt;- &quot;What kind of cheese isn&#39;t your cheese? (wonder) Nacho cheese! (groan) (Laugh)&quot;                                                          
    sub(&quot;\\).*&quot;, &quot;&quot;, sub(&quot;.*\\(&quot;, &quot;&quot;, j)) 

Current output is:

    [1] &quot;Laugh&quot;

Desired output is:

    [1] &quot;wonder&quot; &quot;groan&quot;  &quot;Laugh&quot;

How do I search in an array with preg_match?

Example:

        $items[] = $match[1];
    } else {
        //Ups! not found!
    }

I&#39;m using this pattern to check the validation of a phone number 

    ^[0-9\-\+]{9,15}$

It&#39;s works for `0771234567` and `+0771234567`,
but I want it to works for `077-1234567` and `+077-1234567` and +077-1-23-45-67 and +077-123-45-6-7

What should I change in the pattern?

I am working with a regex to match file contents:

    &gt; (get-content $_) -match $somePattern
    the line of text that matches the pattern

this returns true, a match, however my $matches variable remains null. 

    &gt; $matches -eq $null
    True

Shouldn&#39;t $matches have the match groups in it?

Powershell: match operator returns true but $matches is null

I need to convert string like &quot;/[\w\s]+/&quot; to regular expression.

    &quot;/[\w\s]+/&quot; =&gt; /[\w\s]+/

I tried using different `Regexp` methods like:

`Regexp.new(&quot;/[\w\s]+/&quot;) =&gt; /\/[w ]+\//`, similarly `Regexp.compile` and `Regexp.escape`. But none of them returns as I expected.

Further more I tried removing backslashes:

`Regexp.new(&quot;[\w\s]+&quot;) =&gt; /[w ]+/ ` But not have a luck.

Then I tried to do it simple:

    str = &quot;[\w\s]+&quot;
    =&gt; &quot;[w ]+&quot;

It escapes. Now how could string remains as it is and convert to a regexp object?
