equivalent to Java's toString()?

[Gabriel Cooper]

What is the python equivalent to java's toString()?

When debugging I want to be able to basically be able to do this:

    print MyObjectInstance

or
    print str(MyObjectInstance)

and have it print out formatted output along the lines of:

    Object properties: Red=0 Yellow=0 Blue=255

currently I get something like this:

    <Some Object at 0xff32ffca3>

In java it would look like this:

class SomeClass {
    [...]
    String toString() {
       return new String("Object properties: Red=" + red + " Yellow: " + 
yellow + " Blue: " + blue);
    }
}
