Python TypeError: unhashable type: 'list' reading a CSV

Question

I'm trying to learn python to implement a user agent transformation script in our analytics database. I imported the user_agents lib to do the conversion and show me the user data. When executing this script in python reading a csv file that I extracted containing the user_agents (the csv has only one column) it returns this error:

TypeError: nailshable type: 'list'

Here is the script I am using:

import csv
from user_agents import parse

with open ('UserAgent.csv', 'r') as csv_file:
    csv_reader = csv.reader (csv_file)
    for line in csv_reader:
        print (parse (line))

Answer 1

The parse method takes a string as an argument. However, in your code, each line is a list and not a string, you can try this:

with open('UserAgent.csv', 'r') as csv_file:
    csv_reader = csv.reader(csv_file)
    for line in csv_reader:
        print( parse(' '.join(line)) )
