Is something like this possible in python scripts?
<dtml-in Catalog size=5>
<dtml-var title>
</dtml-in>
Not sure, what you want to achieve in detail....
The above DTML code generates a string containing of up to
   5 titles.

   In my answer below, I expect you do not want to generate
   a string but a list.

     l=[]
     r= context.Catalog()
     n= min(5,len(r))
     for i in range(n):
       l.append(r[i].title)
     return l

"dtml-in" tries hard not to call "len(r)" by using:

  try: r[4]
  except: n= len(r)
  else: n= 5

But I think, this is not relevant for catalog searches
(use it, if I should be wrong).
