Using Objects 573
After you define a class, you can create an object from that class by declaring
a variable as a new class type. In Perl, you create an object by creating a
constructor method commonly called new, such as
Book VI
Chapter 3
my $variablename = classname->new();
In Python, create an object like this:
objectname = new classname();
Perl and Python
To use inheritance in Perl, use the @ISA variable inside a new class, such as
package newobject;
use class2inheritfrom;
@ISA = qw(class2inheritfrom);
To use inheritance in Python, identify the class to inherit from when you
create a new class, such as
class ClassName (class2inheritfrom):
Data
Data
def methodname (self):

To inherit from multiple classes in Python, define additional classes, separated
by a comma, such as
class ClassName (class2inheritfrom, anotherclass):
Data
