#FDResult(DeviceID='NR0951115', PageNum=[2,3,4,5])]
bla = [FDResult(DeviceID='NR0951115', PageNum=[1])] #how to declare bla as FDResult array and blank data inside,Length of bla should equal 0
bla.append(FDResult(DeviceID='NR0951112', PageNum=[2]))
print(len(bla))
bla[0].PageNum.append(16)
如何在Python中声明结构数组?
FD结果数组和里面的空白数据,bla的长度应该等于0
回答
FDResult = namedtuple('FDResult', ['DeviceID', 'PageNum'])
#bla = [FDResult(DeviceID='NR0951113', PageNum=[1,2,3,4]),
#FDResult(DeviceID='NR0951114', PageNum=[17,28,63,64]),
#FDResult(DeviceID='NR0951115', PageNum=[2,3,4,5])]
NodeList = []
Node = FDResult(DeviceID='NR0951113', PageNum=[1,2,3,4])
NodeList.append(Node)
print(len(NodeList))
NodeList[0].PageNum.append(16)
最佳答案
您可以像这样创建 namedtuple 数组。
from collections import namedtuple
MyStruct = namedtuple('MyStruct', 'Mark nPackLen nFlag nGisIp nPort sData sEnd')
NodeList = []
Node = MyStruct(None, '', '', '', '', -1, 0)
for id in range(4):
NodeList.append(Node)
