    <p>I'm stuck on a particular point on something, I'm hoping you guys could perhaps suggest a better method.</p> <p>For each line of file I'm reading I want to get the nth word of the line, store this and print them on a single line.</p> <p>I have the following code:</p> <pre><code>import os p = './output.txt' word_line = ' ' myfile = open(p, 'r') for words in myfile.readlines()[1:]: # I remove the first line because I don't want it current_word = words.strip().split(' ')[4] word_line += current_word print word_line myfile.close() </code></pre> <p>The file it reads looks like this:</p> <pre><code>1 abc-abc.abc (1235456) [AS100] bla 123 etc 2 abc-abc.abc (1235456) [AS10] bla 123 etc 3 abc-abc.abc (1235456) [AS1] bla 123 etc 4 abc-abc.abc (1235456) [AS56] bla 123 etc 5 abc-abc.abc (1235456) [AS8] bla 123 etc 6 abc-abc.abc (1235456) [AS200] bla 123 etc etc </code></pre> <p>My current code outputs the following:</p> <pre><code>[AS100][AS10][AS1][AS56][AS8][AS200] </code></pre> <p>Only problem is, it is not always fixed as the 4th value of the line, as sometimes it appears as 5th, etc or not at all.</p> <p>I'm currently trying out:</p> <pre><code>if re.match("[AS", words): f_word = re.match(".*[(.*)",words) </code></pre> <p>This isn't working out, I'm trying to see if in the current line it finds an open "[" If it does to display the content of it before the closing "]. Move on to the new line and keep on doing this.</p> <p>Eventually have the following desired output:</p> <pre><code>AS100 AS10 AS1 AS56 AS8 AS200 </code></pre> <p>I could really use some advise on this. Thanks</p> <p>EDIT:</p> <pre><code>m = re.search(r'\[AS(.*?)]', words) if m: f_word += ' ' + m.group(1) </code></pre> <p>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.
