That's works:<br>
<br>
bin =['2598.95165', '2541.220308', '221068.0401', 'end',
'4834.581952',<br>

....<br>
'2668.934414', '418.666014', '5216.392132', '760.894589',
'8072.957639',<br>
'346.5905371', 'end']<br>
<br>
avg = []<br>
sp = ",".join(bin).split(',end')<br>
for part in sp:<br>
vals = part.split(',')<br>
sum_ = 0<br>
for v in vals:<br>
if v:<br>
sum_ += float(v)<br>
else:<br>
continue<br>
avg.append(sum_ / len(vals))<br>
<br>
print avg<br>
<br>

OOps, that's works but the result is false.<br>
<br>
There is a final comma in "part" which causes a supernumerary
element (empty) in vals.<br>
<br>
Correction:<br>
<br>
averages = []<br>
items = []<br>
for item in bin:<br>
def get_average(vals):<br>
return sum(vals) / len(vals)<br>
try:<br>
items.append(float(item))<br>
except ValueError:<br>
averages.append(get_average(items))<br>
items = []<br>
<br>
print averages<br>
<br>
This assume the last element of bin is always "end".<br>
