StructPageNum = namedtuple('FDResult', ['DeviceID', 'PageNum','PicSize','PicData'])
PageNumList = []
Node = StructPageNum(DeviceID='NR09', PageNum=[],PicSize=100,PicData='')
PageNumList.append(Node)
PageNumList[0].PicData = 'hello' //how to do at here?
QUESTION
how to edit the value of PicData?
It looks to me like you can use the
_replace
method of a namedtuple to do this pretty easily:This puts a new namedtuple in your
PageNumList
which looks pretty much like the old namedtuple except that we've changed thePicData
"attribute". You can't edit the namedtuple that you have already sincenamedtuple
s are immutable (just like their unnamed counterparts:tuples
)
