I breathe python but have a passing knowledge of Lisp (CL specifically). The one thing I've found is true is the deep extensibility of lisp means every dev is capable of rolling their own thing, thus, just the way things are done in lisp varies from hacker to hacker. Python on the other hand enshrines the idea of having "one way to do it" as part of its values. This is what makes Python pretty uniform across most devs from what I've seen. That seems opposite to the CL way in value and in practice.
