Yeah, of course you can just print them. Or even look at statvfs.py. It's a whopping 15 lines: Constants for interpreting the results of os.statvfs() and os.fstatvfs(). # Indices for statvfs struct members in the tuple returned by # os.statvfs() and os.fstatvfs().

The first three I know, I need to know about the rest The following web page describes them: http://docs.python.org/library/statvfs.html but you already knew that much. So what are you really asking for? You can simply print them, they are integers: import statvfs statvfs.F_FLAG 8 But those values may be specific to a particular python implementation. No reason to assume they'd be the same across OS platforms, or between versions 2.5 and 2.6. The whole thing is deprecated, and is eliminated in 3.0 The term we used to use for these is magic numbers.
