Believe it or not a recruiter can do a very good job filling technical positions without a strong understanding of the technology. All you need to know to get started is how to spot a qualified person, and the hiring manager can help with that.
They seem to want to extrapolate Python expertise to cover everything that uses Python, but it doesn't work like that. I'd love to talk to a recruiter who understands this.
"Why do you need REALLY need a Python developer? Is it because you have problems that a great software engineer without Python knowledge can't solve? If so, give me a couple examples of things you need that only a Python whiz could do, and I will make sure applicants can do that. If we can't attract the right applicants, I will ask you will need to dedicate more time to recruiting or refine your expectations."
I may come to you with a Django job, but I will be prepared to tell you why the hiring manager doesn't need Django experience at all.
