Unless your logger needs to be so flexible as to work in 3rd party apps, why can&amp;#x27;t it be just that simple?&lt;p&gt;Of all the ways this could have been done, it seems like they chose the most complicated.&lt;p&gt;Python&amp;#x27;s lambdas get a lot of grief, but&lt;p&gt;&lt;pre&gt;&lt;code&gt;    def my_logger():
        log1 = lambda msg: log(sys.stderr, msg)
        log2 = lambda msg: log1(filter_function(msg))
        return lambda msg: log2(other_filter_function(msg))
&lt;/code&gt;&lt;/pre&gt;
seems like an entirely sane and uncomplicated way build up a logging function that does what you want it to.  Sure, it&amp;#x27;s not going to be high-performing code (these are Python lambdas after all), but it&amp;#x27;s not like the article&amp;#x27;s version is going to take home any prizes in that department either.</text><parent_chain><item><author>ravenstine</author><text>Why even use a class in any of those cases?
