Ruby has carved space for itself in web application development, but has limited popularity in in other domains. In comparison with Python, Ruby has fewer “old warts” and feels more internally consistent. In a similar manner, the community is more cohesive and is notably newcomer-friendly (newcomer experience is a higher priority and suggestions/help you get will be more consistent), compared to Python.
Don’t worry, although it’s good to learn, IMO it’s still on the wrong side of overused and overrated and could stand to be applied more selectively than it tends to be.
