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
format is useable as part of a filename.

(which defaults to the Python interpreter) is linked against.
Returns a tuple of strings (lib,version) which default to the
given parameters in case the lookup fails.
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.
The file is read and scanned in chunks of chunksize bytes.

The function first looks for a distribution release file in
/etc and then reverts to _dist_try_harder() in case no
suitable files are found.
supported_dists may be given to define the set of Linux
distributions to look for. It defaults to a list of currently
supported Linux distributions identified by their release file
name.
If full_distribution_name is true (default), the full
distribution read from the OS is returned. Otherwise the short
name taken from supported_dists is used.
Returns a tuple (distname,version,id) which default to the
args given as parameters.

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.

An empty string is returned if the value cannot be
determined. Note that many platforms do not provide this
information or simply return the same value as for machine(),
e.g. NetBSD does this.

} n | | | | | | | f } | t | <| S( s Returns a parsed version of Python's sys.version as tuple
(name, version, branch, revision, buildno, builddate, compiler)
referring to the Python implementation name, version, branch,
revision, build number, build date/time as string and the compiler
identification string.
Note that unlike the Python sys.version, the returned value
for the Python version will always include the patchlevel (it
defaults to '.0').
The function returns empty strings for tuple entries that
cannot be determined.
sys_version may be given to parse an alternative version
string, e.g. if the version was read from a different Python
interpreter.

S(
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.
