    <p>I have a program that writes a list to a file. The list is a list of pipe delimited lines and the lines should be written to the file like this:</p> <pre><code>123|GSV|Weather_Mean|hello|joe|43.45 122|GEV|temp_Mean|hello|joe|23.45 124|GSI|Weather_Mean|hello|Mike|47.45 </code></pre> <p>BUT it wrote them line this ahhhh:</p> <pre><code>123|GSV|Weather_Mean|hello|joe|43.45122|GEV|temp_Mean|hello|joe|23.45124|GSI|Weather_Mean|hello|Mike|47.45 </code></pre> <p>This program wrote all the lines into like one line without any line breaks.. This hurts me a lot and I gotta figure-out how to reverse this but anyway, where is my program wrong here? I thought write lines should write lines down the file rather than just write everything to one line..</p> <pre><code>fr = open(sys.argv[1], 'r') # source file fw = open(sys.argv[2]+"/masked_"+sys.argv[1], 'w') # Target Directory Location for line in fr: line = line.strip() if line == "": continue columns = line.strip().split('|') if columns[0].find("@") &gt; 1: looking_for = columns[0] # this is what we need to search else: looking_for = "Dummy@dummy.com" if looking_for in d: # by default, iterating over a dictionary will return keys new_line = d[looking_for]+'|'+'|'.join(columns[1:]) line_list.append(new_line) else: new_idx = str(len(d)+1) d[looking_for] = new_idx kv = open(sys.argv[3], 'a') kv.write(looking_for+" "+new_idx+'\n') kv.close() new_line = d[looking_for]+'|'+'|'.join(columns[1:]) line_list.append(new_line) fw.writelines(line_list) </code></pre>

    1. COIt seems like you are not appending `"\n"` anywhere in your `line_list`.

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.
