6.29.5.1 StreamHandler
</A>
The
<tt class=
"class">StreamHandler
</tt> class sends logging output to streams such as
<var>sys.stdout
</var>,
<var>sys.stderr
</var> or any file-like object (or, more
precisely, any object which supports
<tt class=
"method">write()
</tt> and
<tt class=
"method">flush()
</tt>
<dl><dt><table cellpadding=
"0" cellspacing=
"0"><tr valign=
"baseline">
<td><nobr><b><span class=
"typelabel">class
</span> <tt id='l2h-
2507' xml:id='l2h-
2507'
class=
"class">StreamHandler
</tt></b>(
</nobr></td>
<td><var></var><big>[
</big><var>strm
</var><big>]
</big><var></var>)
</td></tr></table></dt>
Returns a new instance of the
<tt class=
"class">StreamHandler
</tt> class. If
<var>strm
</var> is
specified, the instance will use it for logging output; otherwise,
<var>sys.stderr
</var> will be used.
<dl><dt><table cellpadding=
"0" cellspacing=
"0"><tr valign=
"baseline">
<td><nobr><b><tt id='l2h-

2508'
class=
"method">emit
</tt></b>(
</nobr></td>
<td><var>record
</var>)
</td></tr></table></dt>
If a formatter is specified, it is used to format the record.
The record is then written to the stream with a trailing newline.
If exception information is present, it is formatted using
<tt class=
"function">traceback.print_exception()
</tt> and appended to the stream.
<dl><dt><table cellpadding=
"0" cellspacing=
"0"><tr valign=

class=
"method">flush
</tt></b>(
</nobr></td>
<td><var></var>)
</td></tr></table></dt>
Flushes the stream by calling its
<tt class=
"method">flush()
</tt> method. Note that
the
<tt class=
"method">close()
</tt> method is inherited from
<tt class=
"class">Handler
</tt> and
so does nothing, so an explicit
<tt class=
"method">flush()
</tt> call may be needed
