This sounds like sour grapes. Python is a general-purpose language. Languages like Awk and Perl and Bash are clearly domain-specific, but Python is a pretty normal procedural language (with OO bolted on). The fact that it is dynamic and high-level does not mean it is unsuited for applications or the back-end. People use high-level dynamic languages for servers all the time, like Groovy or Ruby or, hell, even Node.js.

What about Python makes it unsuitable for those purposes other than its performance?
