I am trying to create a dictionary from a txt file "PortList.txt" with information in similar format to below, but keep getting the error "TypeError: unhashable type: 'list'"

TCP 0 Reserved

TCP 1 Port Service Multiplexer

TCP 2 Management Utility

The Key will be the "TCP" and "0" while the value is "Reserved"

My opening code is:

portDictionary = {}
with open('PortList.txt', 'r') as infile:
    for nextLine in infile:   
        lineList = nextLine.split()
        keys = [lineList[0], lineList[1]]
        values = [lineList[2]] 
        #this won't cover all of the words for the value, but for the test it's just for the first word
        portDictionary[keys] = values

You are not posting the part of your code generating the error. – jordanm Apr 04 '17 at 00:34

If by `The Key will be the "TCP" and "0"` you mean `['TCP', '0']`, you can't do that. As the error says, you can't use a list as a key. You can use a tuple, though. – TigerhawkT3 Apr 04 '17 at 00:35

Your edit reveals that you are doing exactly what I thought you were. – TigerhawkT3 Apr 04 '17 at 00:38
Briefly: change the outer square brackets into parentheses when you create `keys`. – TigerhawkT3 Apr 04 '17 at 00:40
when I do that I get "IndexError: list index out of range" for the `keys` – Donnelly Apr 04 '17 at 00:53
Don't try to split blank lines. – TigerhawkT3 Apr 04 '17 at 01:00
