Allow arbitrary single Python commands or blocks of Python code to be run. By default Python commands will not be run as a safeguard for your system. Make sure you trust the source of the ParmEd command before turning this option on.

Error Handling:

These options control how ParmEd handles various errors and warnings that appear occur during the course of Action execution
Prevent scripts from running past unrecognized input and actions that end with an error. In interactive mode, actions with unrecognized inputs and failed actions prevent any changes from being made to the topology, but does not quit the interpreter. This is the default behavior.
Scripts ignore unrecognized input and simply skip over failed actions, executing the rest of the script. Unrecognized input in the interactive interpreter emits a non-fatal warning.
