    <p>I got a program running on my local machine which uses some files. I create the reference to the files by using: <code>os.path.join( tempfile.gettempdir(), 'filename.txt' )</code></p> <p>After that I'm running a program which accepts some parameters <code>--log-file filepath</code> where filepath is one of the files I just explained above.</p> <p>On my machine python creates backslashes for the paths but not double backslashes and the program complains because it's considered an escape character and should be a double backslash.</p> <p>Is there any standard way of making sure that I get a working path with double backslashes in python? I could use regex but I would prefer something similar to what <code>os.</code> provides. Maybe I'm missing something.</p> <p>I'm calling the program using <code>subprocess.Popen</code>:</p> <p><code>self._proc = subprocess.Popen( command.split( ' ' ) )</code></p> <p>where <code>command</code> is something like <code>pcix.exe --log-file file_path</code></p> <p>Also, running a test on my console shows that my python does not produce double backslash for paths:</p> <pre><code>&gt;&gt;&gt; print os.path.join(tempfile.gettempdir(), "test.txt") c:\users\manilo~1\appdata\local\temp\test.txt </code></pre> <p>Leaving out the print command produces the same path:</p> <pre><code>&gt;&gt;&gt; os.path.join(tempfile.gettempdir(), "test.txt") c:\users\manilo~1\appdata\local\temp\test.txt </code></pre> <p>Any idea why?</p> <p>P.S. The platform i'm running is <code>CPython</code></p>

    3. COWindows doesn't use double backslashes; Python string literals do. What you're printing isn't a string literal; it should be a perfectly reasonable Windows path. Leave off the `print` and you'll see it in string literal form with double backslashes.

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.
