Using Objects
Creating a Python dictionary
A dictionary contains values and keys assigned to each value. To create, use
curly brackets like this:
dictionaryname = {key1:value1, key2:value2, key3:value3}
To retrieve a value using its key, use the get command like this:
Variable = dictionary.name.get(key)
Using Objects
Both Perl and Python are true object-oriented programming languages
(unlike C++), so you have no choice but to create and use objects in your
programs. To create an object, you must define a class. In Perl, a typical
class definition looks like this:
package className;
sub new {
my $objectname = {
Data;
Data;
};
bless $objectname, $className;
return $objectname;
sub methodname{
Commands;
Commands;
};
In Python, a class looks like this:
class ClassName:
Data
Data
def methodname (self):
Commands
Commands
Commands
A class lists properties (data) along with one or more methods, which contain
code for manipulating an object in some way.
