unparsable piece of python code for a java developer -


i comming java world , have hard time understand following piece of code.

sortix=['a2', 'a4', 'a1', 'a3', 'a5'] citems=[sortix] print citems while len(citems)>0:     citems=[i[j:k] in citems j,k in ((0,len(i)/2), (len(i)/2,len(i))) if len(i)>1]      print citems

what line citems=[i[j:k] in citems j,k in ((0,len(i)/2), (len(i)/2,len(i))) if len(i)>1]? how write in java (or scala or groovy)?

edit

thx reblochon masque able understand this! if 1 interested, translated groovy statement this: 

citems = citems.findall { -> it.size() > 1}                .collectmany { -> [it.sublist(0, it.size().intdiv(2)), it.sublist(it.size().intdiv(2), it.size())] }

what line do?

citems = [i[j:k] in citems j, k in ((0, len(i) / 2), (len(i) / 2, len(i))) if len(i) > 1]

it partitions each inner lists contained citems 2 sublists of half size (containing each half of elements), except when sublist contains 1 element, ignored.
