Since wrapper function accepts all arguments (*args and **kwargs), the @log decorator can be extended to capture all the parameters passed to the decorated function. We can do this by just iterating over args and kwargs and joining them to form string message to log. @@ -135,7 +135,7 @@ This basic logging decorator looks good and already does what we originally set However in real projects, the logger can itself be abstracted away into its own class that initializes a logger based on certain configuration (such as push log to a cloud sink). In this case its useless to log into console by creating our own logger in the @log decorator. We need a way to pass an existing logger into our decorator at runtime. To do this we can extend the @log decorator to accept logger as an argument.
