&lt;dl class=&quot;function&quot;&gt;

&lt;dd&gt;&lt;p&gt;Queries the given executable (defaults to the Python interpreter binary) for
various architecture information.&lt;/p&gt;
&lt;p&gt;Returns a tuple &lt;tt class=&quot;docutils literal&quot;&gt;&lt;span class=&quot;pre&quot;&gt;(bits,&lt;/span&gt; &lt;span class=&quot;pre&quot;&gt;linkage)&lt;/span&gt;&lt;/tt&gt; which contain information about the bit
architecture and the linkage format used for the executable. Both values are
returned as strings.&lt;/p&gt;
&lt;p&gt;Values that cannot be determined are returned as given by the parameter presets.
If bits is given as &lt;tt class=&quot;docutils literal&quot;&gt;&lt;span class=&quot;pre&quot;&gt;''&lt;/span&gt;&lt;/tt&gt;, the &lt;tt class=&quot;xref c c-func docutils literal&quot;&gt;&lt;span class=&quot;pre&quot;&gt;sizeof(pointer)()&lt;/span&gt;&lt;/tt&gt; (or
&lt;tt class=&quot;xref c c-func docutils literal&quot;&gt;&lt;span class=&quot;pre&quot;&gt;sizeof(long)()&lt;/span&gt;&lt;/tt&gt; on Python version &amp;lt; 1.5.2) is used as indicator for the
supported pointer size.&lt;/p&gt;
&lt;p&gt;The function relies on the system&amp;#8217;s &lt;tt class=&quot;file docutils literal&quot;&gt;&lt;span class=&quot;pre&quot;&gt;file&lt;/span&gt;&lt;/tt&gt; command to do the actual work.
This is available on most if not all Unix  platforms and some non-Unix platforms
and then only if the executable points to the Python interpreter.  Reasonable
defaults are used when the above needs are not met.&lt;/p&gt;
&lt;div class=&quot;admonition note&quot;&gt;
&lt;p class=&quot;first admonition-title&quot;&gt;Note&lt;/p&gt;
&lt;p&gt;On Mac OS X (and perhaps other platforms), executable files may be
universal files containing multiple architectures.&lt;/p&gt;
&lt;p&gt;To get at the &amp;#8220;64-bitness&amp;#8221; of the current interpreter, it is more
reliable to query the &lt;a class=&quot;reference internal&quot; href=&quot;sys.html#sys.maxsize&quot; title=&quot;sys.maxsize&quot;&gt;&lt;tt class=&quot;xref py py-attr docutils literal&quot;&gt;&lt;span class=&quot;pre&quot;&gt;sys.maxsize&lt;/span&gt;&lt;/tt&gt;&lt;/a&gt; attribute:&lt;/p&gt;
&lt;div class=&quot;last highlight-python&quot;&gt;&lt;div class=&quot;highlight&quot;&gt;&lt;pre&gt;&lt;span class=&quot;n&quot;&gt;is_64bits&lt;/span&gt; &lt;span class=&quot;o&quot;&gt;=&lt;/span&gt; &lt;span class=&quot;n&quot;&gt;sys&lt;/span&gt;&lt;span class=&quot;o&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;n&quot;&gt;maxsize&lt;/span&gt; &lt;span class=&quot;o&quot;&gt;&amp;gt;&lt;/span&gt; &lt;span class=&quot;mi&quot;&gt;2&lt;/span&gt;&lt;span class=&quot;o&quot;&gt;**&lt;/span&gt;&lt;span class=&quot;mi&quot;&gt;32&lt;/span&gt;
&lt;/pre&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;/div&gt;
&lt;/dd&gt;&lt;/dl&gt;

&lt;dl class=&quot;function&quot;&gt;
&lt;dt id=&quot;platform.machine&quot;&gt;
&lt;tt class=&quot;descclassname&quot;&gt;platform.&lt;/tt&gt;&lt;tt class=&quot;descname&quot;&gt;machine&lt;/tt&gt;&lt;big&gt;(&lt;/big&gt;&lt;big&gt;)&lt;/big&gt;&lt;a class=&quot;headerlink&quot; href=&quot;#platform.machine&quot; title=&quot;Permalink to this definition&quot;&gt;¶&lt;/a&gt;&lt;/dt&gt;
&lt;dd&gt;&lt;p&gt;Returns the machine type, e.g. &lt;tt class=&quot;docutils literal&quot;&gt;&lt;span class=&quot;pre&quot;&gt;'i386'&lt;/span&gt;&lt;/tt&gt;. An empty string is returned if the
value cannot be determined.&lt;/p&gt;
&lt;/dd&gt;&lt;/dl&gt;

&lt;dl class=&quot;function&quot;&gt;
&lt;dt id=&quot;platform.node&quot;&gt;
&lt;tt class=&quot;descclassname&quot;&gt;platform.&lt;/tt&gt;&lt;tt class=&quot;descname&quot;&gt;node&lt;/tt&gt;&lt;big&gt;(&lt;/big&gt;&lt;big&gt;)&lt;/big&gt;&lt;a class=&quot;headerlink&quot; href=&quot;#platform.node&quot; title=&quot;Permalink to this definition&quot;&gt;¶&lt;/a&gt;&lt;/dt&gt;
&lt;dd&gt;&lt;p&gt;Returns the computer&amp;#8217;s network name (may not be fully qualified!). An empty
string is returned if the value cannot be determined.&lt;/p&gt;
&lt;/dd&gt;&lt;/dl&gt;

&lt;dl class=&quot;function&quot;&gt;
&lt;dt id=&quot;platform.platform&quot;&gt;
&lt;tt class=&quot;descclassname&quot;&gt;platform.&lt;/tt&gt;&lt;tt class=&quot;descname&quot;&gt;platform&lt;/tt&gt;&lt;big&gt;(&lt;/big&gt;&lt;em&gt;aliased=0&lt;/em&gt;, &lt;em&gt;terse=0&lt;/em&gt;&lt;big&gt;)&lt;/big&gt;&lt;a class=&quot;headerlink&quot; href=&quot;#platform.platform&quot; title=&quot;Permalink to this definition&quot;&gt;¶&lt;/a&gt;&lt;/dt&gt;
&lt;dd&gt;&lt;p&gt;Returns a single string identifying the underlying platform with as much useful
information as possible.&lt;/p&gt;
&lt;p&gt;The output is intended to be &lt;em&gt;human readable&lt;/em&gt; rather than machine parseable. It
may look different on different platforms and this is intended.&lt;/p&gt;
&lt;p&gt;If &lt;em&gt;aliased&lt;/em&gt; is true, the function will use aliases for various platforms that
report system names which differ from their common names, for example SunOS will
be reported as Solaris.  The &lt;a class=&quot;reference internal&quot; href=&quot;#platform.system_alias&quot; title=&quot;platform.system_alias&quot;&gt;&lt;tt class=&quot;xref py py-func docutils literal&quot;&gt;&lt;span class=&quot;pre&quot;&gt;system_alias()&lt;/span&gt;&lt;/tt&gt;&lt;/a&gt; function is used to implement
this.&lt;/p&gt;
&lt;p&gt;Setting &lt;em&gt;terse&lt;/em&gt; to true causes the function to return only the absolute minimum
information needed to identify the platform.&lt;/p&gt;
&lt;/dd&gt;&lt;/dl&gt;

&lt;dl class=&quot;function&quot;&gt;
&lt;dt id=&quot;platform.processor&quot;&gt;
&lt;tt class=&quot;descclassname&quot;&gt;platform.&lt;/tt&gt;&lt;tt class=&quot;descname&quot;&gt;processor&lt;/tt&gt;&lt;big&gt;(&lt;/big&gt;&lt;big&gt;)&lt;/big&gt;&lt;a class=&quot;headerlink&quot; href=&quot;#platform.processor&quot; title=&quot;Permalink to this definition&quot;&gt;¶&lt;/a&gt;&lt;/dt&gt;
&lt;dd&gt;&lt;p&gt;Returns the (real) processor name, e.g. &lt;tt class=&quot;docutils literal&quot;&gt;&lt;span class=&quot;pre&quot;&gt;'amdk6'&lt;/span&gt;&lt;/tt&gt;.&lt;/p&gt;
&lt;p&gt;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
&lt;a class=&quot;reference internal&quot; href=&quot;#platform.machine&quot; title=&quot;platform.machine&quot;&gt;&lt;tt class=&quot;xref py py-func docutils literal&quot;&gt;&lt;span class=&quot;pre&quot;&gt;machine()&lt;/span&gt;&lt;/tt&gt;&lt;/a&gt;.  NetBSD does this.&lt;/p&gt;
&lt;/dd&gt;&lt;/dl&gt;

&lt;dl class=&quot;function&quot;&gt;
&lt;dt id=&quot;platform.python_build&quot;&gt;
&lt;tt class=&quot;descclassname&quot;&gt;platform.&lt;/tt&gt;&lt;tt class=&quot;descname&quot;&gt;python_build&lt;/tt&gt;&lt;big&gt;(&lt;/big&gt;&lt;big&gt;)&lt;/big&gt;&lt;a class=&quot;headerlink&quot; href=&quot;#platform.python_build&quot; title=&quot;Permalink to this definition&quot;&gt;¶&lt;/a&gt;&lt;/dt&gt;
&lt;dd&gt;&lt;p&gt;Returns a tuple &lt;tt class=&quot;docutils literal&quot;&gt;&lt;span class=&quot;pre&quot;&gt;(buildno,&lt;/span&gt; &lt;span class=&quot;pre&quot;&gt;builddate)&lt;/span&gt;&lt;/tt&gt; stating the Python build number and
date as strings.&lt;/p&gt;
&lt;/dd&gt;&lt;/dl&gt;

&lt;dl class=&quot;function&quot;&gt;
&lt;dt id=&quot;platform.python_compiler&quot;&gt;

&lt;dd&gt;&lt;p&gt;Returns a string identifying the compiler used for compiling Python.&lt;/p&gt;
&lt;/dd&gt;&lt;/dl&gt;

&lt;dl class=&quot;function&quot;&gt;
&lt;dt id=&quot;platform.python_branch&quot;&gt;

&lt;dd&gt;&lt;p&gt;Returns a string identifying the Python implementation SCM branch.&lt;/p&gt;

&lt;dd&gt;&lt;p&gt;Returns a string identifying the Python implementation. Possible return values
are: &amp;#8216;CPython&amp;#8217;, &amp;#8216;IronPython&amp;#8217;, &amp;#8216;Jython&amp;#8217;, &amp;#8216;PyPy&amp;#8217;.&lt;/p&gt;

&lt;p&gt;Note that unlike the Python &lt;tt class=&quot;docutils literal&quot;&gt;&lt;span class=&quot;pre&quot;&gt;sys.version&lt;/span&gt;&lt;/tt&gt;, the returned value will always

&lt;p&gt;As a hint: &lt;em&gt;ptype&lt;/em&gt; is &lt;tt class=&quot;docutils literal&quot;&gt;&lt;span class=&quot;pre&quot;&gt;'Uniprocessor&lt;/span&gt; &lt;span class=&quot;pre&quot;&gt;Free'&lt;/span&gt;&lt;/tt&gt; on single processor NT machines

to the OS version being free of debugging code. It could also state &lt;em&gt;&amp;#8216;Checked&amp;#8217;&lt;/em&gt;

ranges, etc.&lt;/p&gt;

&lt;dd&gt;&lt;p&gt;This is an old version of the functionality now provided by

&lt;p&gt;The only difference between the two is that &lt;tt class=&quot;docutils literal&quot;&gt;&lt;span class=&quot;pre&quot;&gt;dist()&lt;/span&gt;&lt;/tt&gt; always

&lt;dd&gt;&lt;p&gt;Tries to determine the name of the Linux OS distribution name.&lt;/p&gt;
&lt;p&gt;&lt;tt class=&quot;docutils literal&quot;&gt;&lt;span class=&quot;pre&quot;&gt;supported_dists&lt;/span&gt;&lt;/tt&gt; 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.&lt;/p&gt;
&lt;p&gt;If &lt;tt class=&quot;docutils literal&quot;&gt;&lt;span class=&quot;pre&quot;&gt;full_distribution_name&lt;/span&gt;&lt;/tt&gt; is true (default), the full distribution read
from the OS is returned. Otherwise the short name taken from
&lt;tt class=&quot;docutils literal&quot;&gt;&lt;span class=&quot;pre&quot;&gt;supported_dists&lt;/span&gt;&lt;/tt&gt; is used.&lt;/p&gt;
&lt;p&gt;Returns a tuple &lt;tt class=&quot;docutils literal&quot;&gt;&lt;span class=&quot;pre&quot;&gt;(distname,version,id)&lt;/span&gt;&lt;/tt&gt; which defaults to the args given as
parameters.  &lt;tt class=&quot;docutils literal&quot;&gt;&lt;span class=&quot;pre&quot;&gt;id&lt;/span&gt;&lt;/tt&gt; is the item in parentheses after the version number.  It
is usually the version codename.&lt;/p&gt;
&lt;p class=&quot;versionadded&quot;&gt;
&lt;span class=&quot;versionmodified&quot;&gt;New in version 2.6.&lt;/span&gt;&lt;/p&gt;

&lt;span class=&quot;pre&quot;&gt;version)&lt;/span&gt;&lt;/tt&gt; which default to the given parameters in case the lookup fails.&lt;/p&gt;
&lt;p&gt;Note that this function has intimate knowledge of how different libc versions
add symbols to the executable is probably only usable for executables compiled
using &lt;strong class=&quot;program&quot;&gt;gcc&lt;/strong&gt;.&lt;/p&gt;
