list updating

[clodemil]

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. So the idea
is to make it automatic using accessory variables x and y and extract
elements thereof.

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]]
# [[P systolic,P diastolic,Pulse rate]]
temps=[1,18,24,28,49,87,101,108,113,116,122,133,156,161,166,170,180] #
Hours
Sys=[172,181,146,191,171,157,180,142,169,162,167,166,145,163,192,184,151]
Dia=[91,88,88,85,92,93,84,77,80,76,104,81,78,98,90,85,77]
Pulse=[57,58,56,59,50,55,48,60,45,59,73,53,59,58,50,60,77]
control=[len(temps),len(Sys),len(Dia),len(Pulse)] #all should be equal

x=[[185,82,57]] #new value to be appended to mesures
y=185 #new value to be appended to temps

mesures=mesures+x #appending new value
temps=temps + [y] #appending new value
Sys=Sys + [x[0][0]] #appending new value
Dia + [x[0][1]] #appending new value
Pulse + [x[0][2]] #appending new value
print control
print(mesures)
print temps
print Sys

JOY: It works

DISAPPOINTMENT: It works ONLY if I call the lists on their own and NOT
if they are called inside another cell:
they then appear in the original unappended form:

for i,j in enumerate(temps):
for k,l in enumerate(mesures):
for m,n in enumerate(heuresF):
if m==k:
if i==k:
print "Mesure n°",i,l,n

What am I doing wrong ?

TIA.

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)

Jim,

Thank you, that was what I needed: now I can use one single list of 5-
tuples and update only once!

Claude.
