* Improve starred expressions (deepspeedai#696)

* Improve starred expressions

`deepspeed/profiling/flops_profiler/profiler.py` uses starred expressions
that are no longer valid with [PEP 617][1]. The new Python parser is in 3.9,
and this change allows DeepSpeed to run with the newest Python version. I have
not checked all locations that has this issue. However, this change allows me
to run simple examples.

* Match style for "Improve starred expressions", although readability suffers

The style guide might need to be updated for this new use case of expressions.
Python [Issue 40631][1] includes more discussion on the change.
