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.

Confusion between commands.Bot and discord.Client | Which one should I use?

Whenever you look at YouTube tutorials or code from this website there is a real variation. Some developers use client = discord.Client(intents=intents) while the others use bot = commands.Bot(command_prefix="something", intents=intents) . Now I know slightly about the difference but I get errors from different places from my code when I use either of them and its confusing. Especially since there has a few changes over the years in discord.py it is hard to find the real difference. I tried sticking to discord.Client then I found that there are more features in commands.Bot . Then I found errors when using commands.Bot . An example of this is: When I try to use commands.Bot client = commands.Bot(command_prefix=">",intents=intents) async def load(): for filename in os.listdir("./Cogs"): if filename.endswith(".py"): client.load_extension(f"Cogs.{filename[:-3]}") The above doesnt giveany response from my Cogs ...
