Is there a Python equivalent to Perl's Data::Dumper for inspecting data structures?

Question

Is there a Python module that can be used in the same way as Perl\'s Data::Dumper module?

Edit: Sorry, I should have been clearer. I was mainly afte

I too have been using Data::Dumper for quite some time and have gotten used to its way of displaying nicely formatted complex data structures. pprint as mentioned above does a pretty decent job, but I didn't quite like its formatting style. That plus pprint doesn't allow you to inspect objects like Data::Dumper does:

Searched on the net and came across these:

https://gist.github.com/1071857#file_dumper.pyamazon

>>> y = { 1: [1,2,3], 2: [{'a':1},{'b':2}]}

>>> pp = pprint.PrettyPrinter(indent = 4)
>>> pp.pprint(y)
{   1: [1, 2, 3], 2: [{   'a': 1}, {   'b': 2}]}

>>> print(Dumper.dump(y)) # Dumper is the python module in the above link

{
    1: [
        1 
        2 
        3
    ] 
    2: [
        {
            'a': 1
        } 
        {
            'b': 2
        }
    ]
}

>>> print(Dumper.dump(pp))

instance::pprint.PrettyPrinter
    __dict__ :: {
        '_depth': None 
        '_stream': file:: > 
        '_width': 80 
        '_indent_per_level': 4
    }

Also worth checking is http://salmon-protocol.googlecode.com/svn-history/r24/trunk/salmon-playground/dumper.py It has its own style and seems useful too.
