Only the **config.p**y and its test: **test_config.py** need to be reviewed. The rest differences are from old revision.
# Created a new config.py for [[ https://docs.dagster.io/tutorial/basics_solids#parametrizing-solids-with-config | parametrizing-solids-with-config ]]. Please review the config.py and its test: test_config.py
# The basics_solids.mdx and the two images haven't been modified according to the new config.py. Please expect the update in [Part2]
# The change in test_cli_invocations.py was modified to pass tests in previous version; however, it will be removed in [Part 2] because of duplicate.
