Just another hack can be like this   I have Array of strings which I need to concatenate  So I added that array into dictionary and then used it inside for loop which worked      set dict1     e            for i in list1       if dict1 update   e  dict1 e     i     i         endif       endfor       set layer string   dict1  e

My bad  in trying to simplify it  I went too far  actually stuffs is a record of all kinds of info  I just want the id in it    stuffs     123  first  last    456  first  last     I want my sting to be   my sting    123  456    My original code should have looked like this      set my string            for stuff in stuffs       set my string   my string   stuff id             endfor     Thinking about it  stuffs is probably a dictionary  but you get the gist   Yes I found the join filter  and was going to approach it like this       set my string             for stuff in stuffs        do my string append stuff id         endfor        my string join            But the append doesn t work without importing the extensions to do it  and reading that documentation gave me a headache  It doesn t explicitly say where to import it from or even where you would put the import statement  so I figured finding a way to concat would be the lesser of the two evils

If you can t just use filter join but need to perform some operations on the array s entry      for entry in array    User    entry attribute1    has id    entry attribute2       if not loop last        endif       endfor

You can use   if you know all the values are strings  Jinja also provides the   operator  which will ensure all values are converted to string first      set my string   my string   stuff
