    <pre><code>bb = {} ss = {} for i in range(5): # i are the different days for row in ps: # ps = different dataframes a=row[i:i+1] DE = a['Daily_Error'][0] Date = a.index[0] Identifier = (a.columns[0],a.columns[1]) if DE &gt; 1 : if format(Identifier) in ss: ss[format(Identifier)].append([np.log(Price1)]) else: ss[format(Identifier)]=[np.log(Price1)] print 'YES', format(Date) if xy &lt; -0.006: print 'STOP' ss.clear() bb.clear() bb = {} ss = {} break </code></pre> <p>I would like to break the inner loop when xy&lt;-0.006 and continue with the outer loop [i+1]. Additionally, I would like to delete the dictionary bb, ss and fill them during the next loop. However, this is not working. How can I circumvent the problem without rewriting the whole code or using another data structure?</p> <p>FYI: the break works when I just use:</p> <pre><code> if xy &lt; -0.006: print 'STOP' break </code></pre> <p>Considering the first 4 Days I get:</p> <pre><code>YES 2005-09-19 00:00:00 0 YES 2005-09-19 00:00:00 0 YES 2005-09-19 00:00:00 0 YES 2005-09-20 00:00:00 STOP YES 2005-09-21 00:00:00 0 YES 2005-09-19 00:00:00 0 YES 2005-09-19 00:00:00 0 YES 2005-09-22 00:00:00 YES 2005-09-20 00:00:00 STOP YES 2005-09-23 00:00:00 0 YES 2005-09-19 00:00:00 0 YES 2005-09-19 00:00:00 0 </code></pre> <p>Why does the iteration start at 2005-09-19 again?</p> <p>EDIT2: Narrowed down the issue! The issue is indeed that code-block: </p> <pre><code> if DE &gt; 1 : </code></pre> <p>But why does the code start at iteration zero if I break the inner loop? and it only happens after I delete bb and ss... I do not understand it , sorry!</p>

    1. COThe `break` stmt always exits only the inner loop. Also the `bb` and `ss` are cleared correctly. What is exactly not working for you in this piece of code?

    3. COWe don't know the data, the params you use there...It is impossible to tell what is wrong there. Try to narrow down the problem and the question.

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.
