    <p>I have a rather large string that I want to write to a python file object. Currently, when I try to write this string only the LAST row gets written to the file. I've tested to ensure that the variable holding the large string is infact <code>&lt;type 'str'&gt;</code>. Here is the sample content:</p> <pre><code>"0008788014065251","Rush Running - Bentonville","1030643167","5,788.00","11.55","5.77" "0008788014065271","Rush Running - Fayetteville","1030643159","1,577.00","3.16","1.58" "0008788014108297","Snow Ball Express","2423373737","11.00","0.04","0.02" "0008788014108354","Snow Ball Express","2423378892","1,421.00","5.69","2.84" "0008788014108374","Snow Ball Express","2423378959","59.00","0.24","0.12" "0008788014110860","Sound Master","2423477231","135.00","0.54","0.27" "0008788014074301","The Baby's Room","1030669816","6,912.00","13.82","6.91" "0008788014110760","The Reserve","2423470822","715.00","2.86","1.43" "0008788014077339","Tool Town LLC","1171354079","438.00","0.88","0.44" </code></pre> <p>I want to write this to a file but everytime I do a <code>file.write()</code> I get only the last row. I'm using this simple file open and write procedure:</p> <pre><code>#link is a url to a csv file export = urllib2.urlopen( link ) content = export.read() with open("somefile.csv", "w") as file: try: file.write( content ) except Exception, e: raise e </code></pre> <p>I read that I should be iterating over <code>content</code> with a <code>for</code> loop; but, since <code>content</code> is a string and not a list/tuple, the <code>for</code> loop will explode to each letter and write the letter on a separate row.</p> <p>Any ideas how to write this type of content to a file?</p>

    1. COCan you just `print len(content)` just to verify? Can you tell us the result?

    2. COWhat do you get if you examine `content` using `repr`? Have you checked for carriage returns or other escape characters?

    3. COWhat you could do is first split by newline, and then split by comma, in order to get the list structure which is easily writable (so from string to one level list to two level list). EDIT: Actually, I think you would only have to split by newline.

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.
