© # once a module is loaded
© # import mymodule
© # one can find all the names it
© # export with dir()
©
© import sys
© print dir(sys)
©
© # without argument it gives the names
© # you've defined
© print dir()
©
© # to find a list of built-in names
© # import the module __builtin__
© # and use dir on it.
© import __builtin__
© print dir(__builtin__ )

© ----------------
© # in Perl, Perl experts can achieve
© # similar functionality by, for example:
©
© use Data::Dumper ('Dumper');
© print Dumper \%Data::Dumper: :;
©
© # it has to do with understanding the inner
© # mechanisms of Perl's module system.
