Hi list,
I use an iterator two times in a python code and I wantto reset it to the starting point before to reuse it.
In this way I hope to be more quick.
# first use of the iterator
iterator = layer.dataProvider().getFeatures()
for feature in iterator:
# operations
# than, a second time I have to use the operator, in a following part of the code:
for feature in iterator:
# other operations
But it doesn't start from the first feature!
I try with:
iterator.rewind()
between the two blocks, but it doesn't work.
Thanks.
