[perl-python] 20050120 find functions in modules

P: n/a
# -*- coding: utf-8 -*-
# Python

# 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__)

# see
# http://python.org/doc/2.3.4/tut/node8.html

----------------
# 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.
