dictionaries TypeError: unhashable type:set

I am attempting to split a string and then take a keyword from that string and find it in a dictionary. I would then want to call out that part of the dictionary, but i run into this error -

TypeError: unhashable type:set

- on the last line: 

solutions = {'display': 'take it to a specialist to get fixed','screen':'test'}
problems = ['display','screen','cracked','broken','clear']``
words = ()
query = input("What is the problem? ")
query_split = query.split()
words = query_split
keyword = set(words) & set(problems)
print(keyword)
print (solutions[keyword])

I'm not sure that any of the other answerers are trying to understand what you're doing.

Try this. I'm not sure what you plan on for problems, but this will at least run and hopefully get you in the right direction:

solutions = {'display': 'take it to a specialist to get fixed','screen':'test'}
problems = ['display','screen','cracked','broken','clear']
query = raw_input("What is the problem? ")
for word in query.split():
    print(word)
    print(solutions.get(word))

Notice the change of input to raw_input and accessing the keys of the dictionary as str types rather than a set.

When you do keyword = set(words) & set(problems), keyword becomes a set. You probably want to set keyword to an element from that set using the pop function.

i.e.

keyword = keyword.pop()
