Often in a loop in a template it's handy to know what's next up, previously up, if this is the first or last item in the sequence, etc. These can be awkward to manage in a normal Python loop, but using the looper you can get a better sense of the context. Use like:: >>> for loop, item in looper(['a', 'b', 'c']): ... print("%s %s" % (loop.number, item)) ... if not loop.last: ... print('---') 1 a --- 2 b --- 3 c tlooperiÿÿÿÿNcBs)eZdZd„Zd„Zd„ZRS(s¤ Helper for looping (particularly in templates) Use this like:: for loop, item in looper(seq): if loop.first: ... cCs ||_dS(N(tseq(tselfR((s;/usr/local/lib/python2.7/dist-packages/paste/util/looper.pyt__init__%scCs t|jƒS(N(t looper_iterR(R((s;/usr/local/lib/python2.7/dist-packages/paste/util/looper.pyt__iter__(scCsd|jj|jfS(Ns <%s for %r>(t __class__t__name__R(R((s;/usr/local/lib/python2.7/dist-packages/paste/util/looper.pyt__repr__+s(Rt __module__t__doc__RRR(((s;/usr/local/lib/python2.7/dist-packages/paste/util/looper.pyRs   RcBs)eZd„Zd„Zd„ZeZRS(cCst|ƒ|_d|_dS(Ni(tlistRtpos(RR((s;/usr/local/lib/python2.7/dist-packages/paste/util/looper.pyR1scCs|S(N((R((s;/usr/local/lib/python2.7/dist-packages/paste/util/looper.pyR5scCsY|jt|jƒkr!t‚nt|j|jƒ|j|jf}|jd7_|S(Ni(R tlenRt StopIterationtloop_pos(Rtresult((s;/usr/local/lib/python2.7/dist-packages/paste/util/looper.pytnext8s  %(RR RRRt__next__(((s;/usr/local/lib/python2.7/dist-packages/paste/util/looper.pyR/s   RcBs eZd„Zd„Zd„ZeeƒZd„ZeeƒZd„ZeeƒZd„ZeeƒZd„Z ee ƒZ d„Z ee ƒZ d„Z ee ƒZ d „Z ee ƒZ d „Z ee ƒZ d „ZeeƒZdd „Zdd „Zd„ZRS(cCs||_||_dS(N(RR (RRR ((s;/usr/local/lib/python2.7/dist-packages/paste/util/looper.pyRBs cCsd|j|j|jfS(Ns(RR (R((s;/usr/local/lib/python2.7/dist-packages/paste/util/looper.pyRFscCs|jS(N(R (R((s;/usr/local/lib/python2.7/dist-packages/paste/util/looper.pytindexJscCs |jdS(Ni(R (R((s;/usr/local/lib/python2.7/dist-packages/paste/util/looper.pytnumberNscCs|j|jS(N(RR (R((s;/usr/local/lib/python2.7/dist-packages/paste/util/looper.pytitemRscCs/y|j|jdSWntk r*dSXdS(Ni(RR t IndexErrortNone(R((s;/usr/local/lib/python2.7/dist-packages/paste/util/looper.pyRVs cCs%|jdkrdS|j|jdS(Nii(R RR(R((s;/usr/local/lib/python2.7/dist-packages/paste/util/looper.pytprevious]scCs |jd S(Ni(R (R((s;/usr/local/lib/python2.7/dist-packages/paste/util/looper.pytoddcscCs |jdS(Ni(R (R((s;/usr/local/lib/python2.7/dist-packages/paste/util/looper.pytevengscCs |jdkS(Ni(R (R((s;/usr/local/lib/python2.7/dist-packages/paste/util/looper.pytfirstkscCs|jt|jƒdkS(Ni(R R R(R((s;/usr/local/lib/python2.7/dist-packages/paste/util/looper.pytlastoscCs t|jƒS(N(R R(R((s;/usr/local/lib/python2.7/dist-packages/paste/util/looper.pytlengthsscCs&|jr tS|j|j|j|ƒS(s Returns true if this item is the start of a new group, where groups mean that some attribute has changed.
