Simple newbie question

[Angelo Secchi]

Hi, 
I'm trying to remove lines with zeros from a list "lista".
The code i'm using is the following:

for line in lista:
	if sum(line == 0) > 0:
	lista.remove(line)


The problem is that the loop stops at the first line with zeros and it
doesn't remove the other lines with zeros (at least if I do not re-run
the loop). Probably I do not understand how the loop works.

Any help ?

Thanks,
