    <p>That way works fine, but I'd do it slightly differently, using <code>list</code> instead of <code>set</code> so we can order the words correctly (<code>set</code> will output words in alphabetical order, not quite what we want):</p> <p><strong>File: q_15125575.py</strong></p> <pre><code>#-*- encoding: utf8 -*- from collections import defaultdict INPUT = """you have requested a debate on this subject in the course of the next few days , during this part-session . {##} sus señorías han solicitado un debate sobre el tema para los próximos días , en el curso de este período de sesiones . {##} 0-0 0-1 1-2 2-3 3-4 4-5 5-6 6-7 7-8 8-9 12-10 13-11 14-11 15-12 16-13 17-14 9-15 10-16 11-17 18-18 17-19 19-21 20-22""" if __name__ == "__main__": english, spanish, trans = INPUT.split(" {##} ") eng_words = english.split(' ') spa_words = spanish.split(' ') transtable = defaultdict(list) for e, s in [i.split('-') for i in trans.split(' ')]: transtable[eng_words[int(e)]].append(spa_words[int(s)]) print(transtable['course']) print(transtable['you']) print(" ".join(transtable['course'])) print(" ".join(transtable['you'])) </code></pre> <p><strong>Output:</strong><br> ['curso']<br> ['sus', 'se\xc3\xb1or\xc3\xadas']<br> curso<br> sus señorías</p> <p>It's slightly longer code as I'm using the actual words instead of the indexes - but this allows you to directly lookup from <code>transtable</code></p> <p><strong>However</strong>, both your method and my method both fail on the same issue: Repeating words.<br> <code>print(" ".join(transtable['this'])</code><br> gives:<br> <code>el este</code><br> It's at least in the order that the words appear though, so it's workable. Want the first occurrence of <code>'this'</code> translated?<br> <code>transtable['this'][0]</code> would give you the first word.</p> <p>And using your code: </p> <pre><code>tt = defaultdict(set) for e, s in [i.split('-') for i in trans.split(' ')]: tt[int(e)].add(int(s)) query = 'this' for i in tt[eng_words.index(query)]: print i </code></pre> <p>Gives:<br> <code>7</code></p> <p>Your code will only print the index of the <em>first</em> occurrence of a word.</p>

    2. COYour code in the question as is won't even work though, it has quite a few errors. You're adding strings to tt{} (`tt[s].add(t)` would give `tt['0'] = '1'` for example). Then when you get the index, you're grabbing it from the raw string `eng`, not the split words. This index is a number, not string, so it will always return nothing. If you change it to be `tt[int(s)].add(int(t))`, the next problem is that it would fail because `spanish.split(" ")` is expecting an integer, not a set. And lastly, (assuming `eng` is the split words), `eng.index(query)` will still only return the first result.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
