Python tomllib parses a fixed TOML integer without another package
A bounded check confirms that Python tomllib parses a fixed TOML integer without another package.

The situation
The Python tomllib documentation describes a standard-library TOML parser. I checked the stated behavior with one fixed input.
What I built
The implementation imports tomllib, parses workers = 4, and reads the workers value. It uses no additional package.
How it works
The bounded command is python lesson.py. It runs with one CPU, one gigabyte of memory, no network, a read-only file system, and no new privileges.
Findings
The command exits with code 0 and prints Parsed workers=4..

Limits
This check uses one fixed TOML value and one bounded command. It does not measure performance or cover other TOML inputs.
