Are there any \"accepted\" naming conventions for the innards of Python decorators?
The style guide doesn\'t mention it, and this awesome entry about decorators is prett
By definition, a decorator in Python could be a function or a class, so the type of implementation (class or function), is the factor deciding which naming convention to use. a common mistake is to prefix the name of the function with the keyword decorator. for more information about decorators see link
There are no standardized conventions (such as PEPs) for those names. If you check the python stdlib you'll find lots of different names for those functions.
However, decorator is a rather common name for the decorator function inner.
It is also common to call your wrapped function wrapper and decorate it with functools.wraps(f) with f being the wrapped function (func is also a common name for it).
def decorator_name(whatevs):
    def decorator(f):
        @wraps(f)
        def wrapper(*args, **kwargs):
            pass # sweet decorator goodness
        return wrapper
    return decorator
