copied!<p>If I type the following at the python.exe command prompt...</p> <pre><code>>>>help('modules') </code></pre> <p>...I get a list of available modules as expected.</p> <p>However when I type the same thing in the IDLE environment (idle.pyw), it throws an error:</p> <pre><code>Traceback (most recent call last): File "<pyshell#1>", line 1, in <module> help('modules') File "C:\Python27\ArcGIS10.1\lib\site.py", line 467, in __call__ return pydoc.help(*args, **kwds) File "C:\Python27\ArcGIS10.1\lib\pydoc.py", line 1727, in __call__ self.help(request) File "C:\Python27\ArcGIS10.1\lib\pydoc.py", line 1766, in help elif request == 'modules': self.listmodules() File "C:\Python27\ArcGIS10.1\lib\pydoc.py", line 1887, in listmodules ModuleScanner().run(callback, onerror=onerror) File "C:\Python27\ArcGIS10.1\lib\pydoc.py", line 1938, in run for importer, modname, ispkg in pkgutil.walk_packages(onerror=onerror): File "C:\Python27\ArcGIS10.1\lib\pkgutil.py", line 105, in walk_packages for importer, name, ispkg in iter_modules(path, prefix): File "C:\Python27\ArcGIS10.1\lib\pkgutil.py", line 147, in iter_modules for name, ispkg in iter_importer_modules(i, prefix): File "C:\Python27\ArcGIS10.1\lib\pkgutil.py", line 211, in iter_modules for fn in os.listdir(path): WindowsError: [Error 5] Access is denied: 'C:\\WINDOWS\\system32\\Msdtc/*.*' </code></pre> <p>Why does Windows say "Access is denied" to IDLE but not the command line? I have tried using "Run as Administrator" on IDLE without success. Do I need to reconfigure IDLE in some way?</p> <p>For information:</p> <p>My installation of Python 2.7.2 (32-bit version running on a Windows 7 64-bit machine) came bundled with ArcGIS 10.1, which uses Python as a scripting language and certain numerical operations (via Numpy). Could this have something to do with the differing behaviour in the prompt and IDLE?</p> <p>The root Python directory is: <code>C:\Python27\ArcGIS10.1\</code>.</p> <p>IDLE is installed at <code>C:\Python27\ArcGIS10.1\Lib\idlelib\idle.pyw</code>.</p> <p>The Python command prompt is installed at: <code>C:\Python27\ArcGIS10.1\python.exe</code>.</p>
