    <p>I am attempting to automate the specification of a sub-directory which one of my scripts requires. The idea is to have the script search the C: drive for a folder of a specific name. In my mind, this begs for a recursive search function. The plan is to check all sub-directories, if none are the desired directory, begin searching the sub-directories of the current sub-directories</p> <p>While researching how to do this, I came across <a href="https://stackoverflow.com/questions/973473/getting-a-list-of-all-subdirectories-in-the-current-directory">this question</a> and started using <code>os.walk(dir).next()[1]</code> to list directories. This had limited success. As the script searched through directories, it would essentially give up and break after, giving the <code>StopIteration</code> error. Sample output is below searching for a sub-directory within <code>TEST1</code>.</p> <pre><code>C:\Python27&gt;test.py curDir: C:\Python27 ['DLLs', 'Doc', 'include', 'Lib', 'libs', 'pyinstaller-2.0', 'Scripts', 'tcl', 'TEST1', 'Tools'] curDir: DLLs [] curDir: Doc [] curDir: include [] curDir: Lib ['bsddb', 'compiler', 'ctypes', 'curses', 'distutils', 'email', 'encodings', 'hotshot', 'idlelib', 'importlib', 'json', 'lib-tk', 'lib2to3', 'logging', 'msilib', 'multiprocessing', 'pydoc_data', 'site-packages', 'sqlite3', 'test', 'unittest', 'wsgiref', 'xml'] curDir: bsddb Traceback (most recent call last): File "C:\Python27\test.py", line 24, in &lt;module&gt; if __name__ == "__main__": main() File "C:\Python27\test.py", line 21, in main path = searcher(os.getcwd()) File "C:\Python27\test.py", line 17, in searcher path = searcher(entry) File "C:\Python27\test.py", line 17, in searcher path = searcher(entry) File "C:\Python27\test.py", line 6, in searcher dirList = os.walk(dir).next()[1] StopIteration </code></pre> <p><code>curDir</code> is the the current directory that is being searched and the next line of output is the list of subdirectories. Once the program finds a directory with no sub-directories, it kicks back up one level and goes to the next directory.</p> <p>I can provide my code if required, but didn't want to initially post it to avoid an even bigger wall of text. </p> <p>My question is: why does the script give up after searching a few folders? Thanks in advance for your help!</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.
