6.6 The <tt class=keyword>print</tt> statement 
</H1>
<a name="l2h-603"></a>

<P>
<dl><dd><pre class=verbatim>
print_stmt:     "print" [ expression ("," expression)* [","] ]
</pre></dl>

<P>
<tt class=keyword>print</tt> evaluates each expression in turn and writes the
resulting object to standard output (see below).  If an object is not
a string, it is first converted to a string using the rules for string 
conversions.  The (resulting or original) string is then written.  A
space is written before each object is (converted and) written, unless 
the output system believes it is positioned at the beginning of a
line.  This is the case (1) when no characters have yet been written
to standard output, (2) when the last character written to standard
output is "<tt class=character>&#92;n</tt>", or (3) when the last write operation on
standard output was not a <tt class=keyword>print</tt> statement.  (In some cases
it may be functional to write an empty string to standard output for
this reason.)
<a name="l2h-604"></a>
<a name="l2h-605"></a>

<P>
A "<tt class=character>&#92;n</tt>" character is written at the end, unless the
<tt class=keyword>print</tt> statement ends with a comma.  This is the only action
if the statement contains just the keyword <tt class=keyword>print</tt>.
<a name="l2h-606"></a>
<a name="l2h-607"></a>

<P>
Standard output is defined as the file object named <tt>stdout</tt>in the built-in module <tt class=module>sys</tt>.  If no such object exists, or if
it does not have a <tt class=method>write()</tt> method, a <tt class=exception>RuntimeError</tt>
exception is raised.
