Question: I'm trying to combine input from a user as part of a regex search. Since I only want the user-provided pattern to be searched in particular lines, I want to combine (i.e., concatenate) the pattern provided with a pattern. What's the best way to do this in python?

Here is my code, which at the moment, doesn't work because an addition operator doesn't seem to be supported by re:

```
import re

q1=re.compile(r'^Organism.*')
q2=re.compile(r'(moth)')
q3=re.compile(r'.*</td>')

s="Organism: moth </td>"

test=re.search(q1+q2+q3,s).group(1)

print "test", test

```

Answer: 
Solved. 

```
$(defaultOptions.removeButton).click(function(){
           $(defaultOptions.copyToLocation).children().last().remove();
       });

```
You can try to explode each of the clonedNode's id in $(defaultOptions.copyToLocation), and grab it by the higher number, than you'll now the last one!

Or simply remove the last children of that, like

```
$(defaultOptions.copyToLocation).children().last().remove();

```
