reformat python scripts with yapf3

We can add yapf3 formatting check of python scripts to the pipeline CI check, similarly to clang-format, with this config:

yapf3 --style='{based_on_style: google; column_limit: 160; use_tabs: True; dedent_closing_brackets: True; indent_width = 8; continuation_indent_width = 8 }' -i FileName.py

I think that these arguments are quite consistent with our clang formatting settings.
