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

[Yoriz]

Show full run able code like mine was
the error

Error:
TypeError: 'in <string>' requires string as left operand, not list

shows that match was assigned as list instead of a string
to try and correct that you converted it into a string
the string ['0/7'] won't match 0/7/CPU0
as it shows in my code you quoted, match should be a string

match='0/7'

v is already a string and does not need converting.
