[BugFix] Remove unnecessary eval() calls in script_parser.py (#7403)

* [BugFix] Remove unnecessary eval() calls in script_parser.py

Replace eval() with direct dict access and slice() construction.
Follows the same pattern as #7390 which removed eval() from utils.py.
No behavior change - all replacements are equivalent to the eval'd
expressions.

* style: format script_parser with black
