Editing Class variable (section)

=== Python ===
<syntaxhighlight lang="python">
class Dog:
    vertebrate_group = 'mammals' # class variable

dog_1 = Dog
print(dog_1.vertebrate_group) # accessing the class variable
</syntaxhighlight>In the above Python code, it does not provide much information as there is only class variable in the Dog class that provide the vertebrate group of dog as mammals. In instance variable, you could customize your own object (in this case, dog_1) by having one or more [[instance variable]]s in the Dog class.
