unworthy and namedtuple or a class could solve the problem.
Thanks for all your kind explanation. Let us close this conversation.

you can return multiple values from a function using a tuple?

Dear Python community,
I am a heavy python user in numerical simulation.
In python 3.8, we will have a new syntax `:=` that could assign values to
variables as part of larger expression like,
```
if (n:=len(a)) > 10:
```
On the other hand, I also think that it would be useful if `:=`
