mysql utilities from stored proc or script?

[Damon Theis]

Sounds simple, I just can figure it out or find the right docs.
I am trying to automate/save a mysqldbcopy command with params to rerun at will or on schedule to update my test environment with the latest production data.
Manually from the workbench utilities shell, I can run
mysqldbcopy \ --source=root:password@localhost:3306 \
--destination=root:password@localhost:3306
production:testing
--drop-first

how the heck do I save this or invoke it from a stored proc in the db or from a .py script file in workbench?
And what are the back slashes for?
Thank you for your help.
