Is this a safe thing to do?

[Phil Schmidt]

The following example works fine (Python 2.3), but is it always safe
to modify a list that is being iterated in a loop, regardless of the
actual contents of the list x? If not, what's a better (safe) way to
do it?

Thanks!


>>> x=[{'f':9},{'f':1},{1:3,'f':9},{'f':3}]
>>> for t in x:
	if t['f'] == 9:
		x.remove(t)

		
>>> x
[{'f': 1}, {'f': 3}]
