    <p>Hi all I am probably missing something obvious</p> <p>Creating list of lists (in C++ notation "vector\\>"), then trying to sort inner lists ("records") using some of the fields as a sort keys. And it would not work. Tryed two different version: with "lambda" and with "itemgetter". There is no error or warning. What am I doing wrong?</p> <p>//<strong><em>*</em>*</strong> my code: start</p> <p>class fwReport:</p> <pre><code>def __init__(self): #each field from firewall log file, 17 all together self.fieldnames = ("date", "time", "action", "protocol", \ "src-ip", "dst-ip", "src-port", "dst-port" \ "size", "tcpflags", "tcpsyn", "tcpack", \ "tcpwin", "icmptype", "icmpcode", "info", "path") self._fields = {} self.mx = list() self.dst_ip = collections.Counter() self.src_ip = collections.Counter() def openfn(self): try: with open(fn) as f: data = f.read() except IOError as err: raise AssertionError("Can't open %s for reading: %s" % (fn, err)) return #make a matrix out of data, smth. like list&lt;list&lt;field&gt;&gt; #skip first 5 lines (file header) for fields in data.split("\n")[5:25]: temp = fields.split(" ")[:6] #take first 7 fields self.src_ip[temp[4]] += 1 #count source IP self.dst_ip[temp[5]] += 1 #count destination IP self.mx.append(temp) #build list of lists #sorted(self.mx, key=itemgetter(5)) #----&gt; does not work sorted(self.mx, key=lambda fields: fields[5]) #--------&gt; does not work for i in range(len(self.mx)): print(i, " ", self.mx[i][5]) #print(self.dst_ip.most_common(16)) #print(self.src_ip.most_common(16)) print(self.mx[:5][:]) #print(len(self.dst_ip)) </code></pre> <h1><em><strong></em>**<em>*</em>**<em>*</em>**<em>*</em></strong></h1> <p>def main():</p> <pre><code>mx = [["a", "b", "c"], ["a", "c", "b"], ["b", "a", "c"]] mx = sorted(mx, key=lambda v: v[1]) for i in range(len(mx)): print(i, " ", mx[i], " ", mx[i], end="\n") </code></pre> <p>0 ['b', 'a', 'c'] ['b', 'a', 'c']</p> <p>1 ['a', 'b', 'c'] ['a', 'b', 'c']</p> <p>2 ['a', 'c', 'b'] ['a', 'c', 'b']</p> <h1><em><strong></em>****</strong></h1> <p>Working fine.</p> <p>@Ned Batchelder - thanks</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.
