Question

I’m new to Python so my question may seem easy to some but then again I’m stuck on my own so I need your help! This is the code that i am having trouble with:

def identify_language(sequence, **common_words):
    result = {}
    for i in common_words:            
        result[i] = 0
    for i in func_op(sequence.lower()):
        for j in common_words:
            if i in common_words[j]:
                result[j] += 1
    return sort(result[0][0])

...

dictionary = {'cro':list_cro, 'eng':list_cro}
language = identify_language('I had a little lamb. It was called Billy.', **dictionary)

I am trying to identify language based on samples which are in list_cro and list_eng (and hopefully others). I am getting KeyError: 0. Additionally, sort and func_op are working fine i tested then separately. What may be the problem?

Also, if i change order of arguments in function (putting list as a first argument and string as second) i am getting syntax error.
Thanks for listening!

Answer 1

At the end of the function, result should look like this: {'cro': X, 'eng': Y}, where X and Y are numbers. I don’t know what your dictionaries are, so I can’t guess what the numbers are. Evaluating result['eng'] will produce a number, as will result['cro'], but there is no 0 key in this dictionary.

Further, the second indexing operation will also give you issues. result['eng'][0] will give you an error because result['eng'] is a number, and you can’t index into a number.

What do you expect the output of this function to look like? Where is sort defined and what is it supposed to do?
