    <p>I have an output (a long one!) from some function, which looks in this way:</p> <pre><code>[[(0.0, 1.0, 2.0), (1.0, 2.0, 0.0), (2.0, 1.0, 0.0)], [(1.6324986294474886e-06, 1.000000272083105, 1.9999992744450537), (1.0, 1.9999985559929883, 9.626713411705526e-07), (1.9999957124111243, 1.000000714598146, 9.527975279416402e-07)], ......................, [(0.00016488526381860965, 1.0000274825531668, 1.9999267116402146), (0.9999999810184469, 1.9998541492231847, 9.723903843230245e-05), (1.9995669148822666, 1.000072183688789, 9.62532545797885e-05)]] </code></pre> <p>I don't like the structure of the output, but it is very convenient to use it in the function, which returns it.</p> <p>But i need to format the output to look this way:</p> <pre><code>0.0 1.0 2.0 A 1.0 2.0 0.0 B 2.0 1.0 0.0 C 1.6324986294474886e-06 1.000000272083105 1.9999992744450537 A 1.0 1.9999985559929883 9.626713411705526e-07 B 1.9999957124111243 1.000000714598146 9.527975279416402e-07 C </code></pre> <p>I have this code:</p> <pre><code>obj = 'A', 'B', 'C' for n in results(): for z in range(len(results()[0])): k = n[z], obj[z] print '\t'.join(map(str, k)) </code></pre> <p>('results' is the name of the function, which returns the big list)</p> <p>It gives me this:</p> <pre><code>(0.0, 1.0, 2.0) A (1.0, 2.0, 0.0) B (2.0, 1.0, 0.0) C (1.6324986294474886e-06, 1.000000272083105, 1.9999992744450537) A (1.0, 1.9999985559929883, 9.626713411705526e-07) B (1.9999957124111243, 1.000000714598146, 9.527975279416402e-07) C </code></pre> <p>I can get this, if I don't add the letter (A, B or C) in the end of the line with this code, so, I thought, maybe to add it somehow differently?</p> <p>Anyway, hoping for your help! Thanks in advance!</p> <p>An unexpected problem... I really want to write the output into a .csv file, so instead of print I use (for now I've chosen the option of using list and appending the letter, as it is more clear to me)</p> <pre><code>with open('table.csv', 'wb') as f: writer = csv.writer(f) for n in results(): for z in range(len(res[0])): k = list(n[z]) k.append(obj[z]) writer.writerows ('\t'.join(map(str, k))) </code></pre> <p>And it doesn't actually work properly, I only get this: </p> <pre><code>0 . 0 1 . 0 2 . 0 A . . . </code></pre> <p>Why do I get so strange formatting, but not what I get with print? It is quite shocking to me...</p>

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.
