I recognize the value of expertise in a language. I recognize that I have touched so many different languages that any "expertise" that I might have possessed at some point has probably passed as I've missed out on new features, etc. I guess I would just expect you to be really knowledgeable and efficient in python!
So I don't think it's an issue, if that's been your job. My job exposes me to a lot of different technologies: many programming languages and endless different software that might be supporting a web application (databases, webservers, firewalls, etc.). I consider my value to be looking at problem and being able to spot 10 different possible points of failure in a system in my mind and order them by priority based on likelihood and ease of troubleshooting. And this is something that I think is only gained through experience and that's what separates me from someone who just started.
Yeah. I wouldn't even say that I'm amazing at Python, not really! Much of my time these days isn't spent writing code. But, I can still get things done quickly. I wouldn't say I'm a superstar, though.
