A data analyst has successfully created a Delta table named sales, which is extensively used by the entire data analysis team for various reporting and analytical tasks. Seeking to maintain the integrity and cleanliness of this data, they have requested assistance from the data engineering team to implement a suite of thorough data validation tests. Notably, while the data analyst team primarily leverages SQL for their operations, the data engineering team prefers using Python within the PySpark framework for their testing procedures. Considering this context, which command should the data engineering team utilize to access the sales Delta table in PySpark?
