I don't agree at all that it's stupid (and I'm someone who'd generally pick Python over Ruby). Fragmentation sucks. Really bad fragmentation sucks more. Python's fragmentation is pretty bad.
It's funny reading this from the Zen of Python "There should be one-- and preferably only one --obvious way to do it." [1] while seeing that there are nearly two independent language/ecosystems with the name Python (namely version 2/3).
