As another answer mentions, Mac OS in the documentation means pre-OS X. In classic Mac OS, <code>stat</code> was emulated, whereas Python <code>stat</code> actually means <code>stat</code> on OS X. Therefore, you don't get the type and creator with os.stat. The corresponding low-level call is <code>getattrlist</code>, but this isn't wrapped by Python (nor should you really use it). You can see exactly what is returned by <code>stat</code> by printing it: <pre><code>>>> import os >>> s = os.stat('foo') >>> s posix.stat_result(st_mode=33152, st_ino=18294505, st_dev=16777218L, st_nlink=1, st_uid=501, st_gid=501, st_size=0, st_atime=1379052292, st_mtime=1379052292, st_ctime=1379052308) </code></pre> Let's set a type and creator on <code>foo</code> to test with: <pre><code>% SetFile -t 'TYPE' -c 'CREA' foo </code></pre> The easy answer in Python 2.x is <code>MacOS.GetCreatorAndType</code>. However, it's gone in 3.x and the underlying mechanisms it uses are deprecated. If your goal is just to get something done for yourself, then by all means use it. <pre><code>>>> import MacOS >>> MacOS.GetCreatorAndType('foo') ('CREA', 'TYPE') </code></pre> A more future-proof mechanism would be to use PyObjC, which works on Python 3.x and does not use deprecated OS X API: <pre><code>>>> from Foundation import NSFileManager, NSFileHFSCreatorCode, NSFileHFSTypeCode >>> attributes = NSFileManager.defaultManager().attributesOfItemAtPath_error_('foo', None)[0] >>> attributes[NSFileHFSTypeCode] 1415139397L >>> attributes[NSFileHFSCreatorCode] 1129465153L </code></pre> These come out as integers because PyObjC has no mapping for four-character codes (nor does it have the appropriate metadata to understand what it's getting). Here's a quick mapping function to retrieve a four-character string: <pre><code>>>> def decode(f): return ''.join(chr(f >> i * 8 & 0xff) for i in xrange(3,-1,-1)) ... >>> decode(attributes[NSFileHFSCreatorCode]) 'CREA' >>> decode(attributes[NSFileHFSTypeCode]) 'TYPE' </code></pre> (Replace <code>xrange</code> with <code>range</code> above if you're using Python 3.) Note that in general, types/creators are not used very much in OS X; their functions have been superseded by file extensions, UTIs, MIME types, per-user and per-document application bindings.

1. COThanks for the comprehensive answer. The background to this project is to convert files from a PPC application running on OS X 10.6. The files *do* actually have Creator and Type codes, and that is how I will identify the files I need to convert as I path.walk() them. Since this will be running on 10.6, and therefore under Python 2, MacOS.GetCreatorAndType() will be fine. Thanks for the pointer.

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.
