you might try using the zip command. If you use the * operator with zip it will unpack the elements into the individual variables Sys, Dia, Pulse =zip(*mesures) mesures.append([181,88,58]) Sys[-1],Dia[-1],Pulse[-1]
of course you can use zip to go the other way too: mesures = zip(Sys, Dia, Pulse) On Sat, Mar 26, 2011 at 5:32 AM, clodemil <ollie...@scarlet.be> wrote: > Hi All, > > Measurements are taken for blood pressure and entered as 3-tuples: > [P_systolic,P_diastolic,Pulse_rate] and put in a list > > mesures=[[172,91,57],[181,88,58],[146,88,56],[191,85,59],[171,92,50], > [157,93,55],[180,84,48],[142,77,60],[169,80,45],[162,76,59], > [167,104,73],[166,81,53],[145,78,59],[163,98,58],[192,90,50], > [184,85,60],[151,77,56]] > > Various elements or the whole tuple are then used for diverse > calculations and yet again output in lists. > A new measurement entails updating ALL lists individually.
