Dive Deeper into "Everything's an Object" in Python and Ruby

It has been claimed that Python, like Ruby, embraces the philosophy that "everything's an object." But is this truly the case?

Python's Perspective: All Objects Carry Attributes and Methods

According to DiveIntoPython.net, everything in Python exists as an object. Objects possess attributes (like properties) and methods (similar to functions). This includes functions' doc attribute, which provides the function's defined documentation. Furthermore, modules like sys contain attributes (e.g., path).

Ruby's View: Objects Defined Broadly

Ruby aligns with this object-oriented concept, as evidenced by its official documentation: "Everything is an object." However, Ruby defines objects more expansively. Not all objects necessarily possess attributes or methods. Moreover, not every object can be inherited from.

Comparing Python and Ruby: Similarities and Differences

Despite their shared commitment to the "everything's an object" concept, Python and Ruby interpret it differently. Python adheres to a looser definition, while Ruby allows for greater flexibility in object instantiation.

For instance, in Ruby, a number like 5 can participate in object-like operations, such as y = 5.plus 6. In Python, such syntax is not supported. This distinction highlights the subtle differences in their implementations of the object-oriented paradigm.
