Setting a variable to a parameter value inline when calling a function

In other languages, like Java, you can do something like this:

String path;
if (exists(path = "/some/path"))
    my_path = path;

the point being that path is being set as part of specifying a parameter to a method call. I know that this doesn't work in Python. It is something that I've always wished Python had.

Is there any way to accomplish this in Python? What I mean here by "accomplish" is to be able to write write both the call to exists and the assignment to path as a single statement with no prior supporting code being necessary.

I'll be OK with it if a way of doing this requires the use of an additional call to a function or method, including anything I might write myself. I spent a little time trying to come up with such a module, but failed to come up with anything that was less ugly than just doing the assignment before calling the function.

Where and how is this Laravel kernel constructor called? [closed]

I am learning Laravel and I am wondering where does this kernel constructor receives its arguments from.

What is not clear to me is where and how the Kernel class is instatiated and the arguments passed to the object calling the constructor.Something similar to; obj = new kernel(arg1,arg2) or, is the framework using some magic functions somewhere? Special gratitude to those who burn their eyeballs and brain cells on this trivia before it goes into a full blown menopause alias "MARKED AS DUPLICATE". To some of the itchy-finger keyboard warriors, a.k.a The mods,because I believe in th...
