Question

python 实现字典嵌套字典

interface_all = dict
...(porttype是一个列表['port1','port2'])
for i in range(len(porttype)):
interface_all[str(porttype[i])]['status']='up'
KeyError: 'port1'
请问应该怎么修改？

Answer 1

from collections import defaultdict

interface_all = defaultdict(dict)
for port in porttype:
interface_all[port]['status'] = 'up'

Answer 2

你要先将绑定为一个空字典，然后才可以循环往这个空字典里面写入键和值。

interface_all={}

porttype=['port1','port2']

for i in range(len(porttype)):

interface_all[str(porttype[i])]={}

interface_all[str(porttype[i])]['status']='up'

print(interface_all)
