It's a jack of all trades but a master of none. Nothing wrong with that until there is. Then you end up with two languages. This works fine for a while. Until you need 3... Next thing you know half your code was rewritten in other languages and cleaned up. Start realizing ya could have started your projects using different tools.

Not pooping on python it's... Fine. But I am not of the opinion that it's a great choice for all projects because technically "it can" do "anything".
