Error 'object has no attribute' when iterating thru a dictionary

[mrapple2020]

Update:
if I do
match = '0/7/CPU0' #match is the 'interface' variable.
Then I get a match now. Ding. Maybe I need to extract the /CPU0 info from the list of CPU value....

Output:

Interface:0/7/CPU0 CPU list:['0/7/CPU0', '1/0/CPU0', '1/2/CPU0']
[0]
Interface:0/7/CPU0 CPU list:['0/7/CPU0', '1/0/CPU0', '1/2/CPU0']
[0]
exit...

Hello, I tried both suggestions and it is not triggering a match. Any other options?

#match is the 'interface' variable. I tried both '0/7' and ['0/7']. It does not find a match.
match='[0/7]' 
    if match:
               for k, v in arch_dic.items():
                   print (f'Interface:{match}   CPU list:{v}')
                   if match in v:

                       #print('Interface {match} is in {v};  PSE2...')
                       print([index for index, value in enumerate(v) if match in value])

#Result of the print above is this. As we can see, there is an interface '0/7' which should cause a match against the CPU list. It is not working. Any ideas?
Interface:['0/5'] CPU list:['0/7/CPU0', '1/0/CPU0', '1/2/CPU0']
Interface:['0/7'] CPU list:['0/7/CPU0', '1/0/CPU0', '1/2/CPU0']
exit...
