possible. It makes this information available via function APIs.
If called from the command line, it prints the platform
information concatenated as single string to stdout. The output

Returns a tuple of strings (lib,version) which default to the

Note that the function has intimate knowledge of how different
libc versions add symbols to the executable and thus is probably
only useable for executables compiled using gcc.

and return a tuple (version,csd,ptype) referring to version
number, CSD level and OS type (multi/single
processor).
As a hint: ptype returns 'Uniprocessor Free' on single
processor NT machines and 'Multiprocessor Free' on multi
processor machines. The 'Free' refers to the OS version being
free of debugging code. It could also state 'Checked' which
means the OS version uses debugging code, i.e. code that
checks arguments, ranges, etc. (Thomas Heller).
Note: this function only works if Mark Hammond's win32
package is installed and obviously only runs on Win32
compatible platforms.

binary) for various architecture information.
Returns a tuple (bits,linkage) which contains information about
the bit architecture and the linkage format used for the
executable. Both values are returned as strings.
Values that cannot be determined are returned as given by the
parameter presets. If bits is given as '', the sizeof(pointer)
(or sizeof(long) on Python version < 1.5.2) is used as
indicator for the supported pointer size.
The function relies on the system's "file" command to do the
actual work. This is available on most if not all Unix
platforms. On some non-Unix platforms where the "file" command
does not exist and the executable is set to the Python interpreter
binary defaults from _default_architecture are used.

s Returns a single string identifying the underlying platform
with as much useful information as possible (but no more :).
The output is intended to be human readable rather than
machine parseable. It may look different on different
platforms and this is intended.
If "aliased" is true, the function will use aliases for
various platforms that report system names which differ from
their common names, e.g. SunOS will be reported as
Solaris. The system_alias() function is used to implement
this.
Setting terse to true causes the function to return only the
absolute minimum information needed to identify the platform.
