usage = resource.getrusage(resource.RUSAGE_SELF)
print(f'CPU time: {usage.ru_utime:.2f} seconds')

Definition and Usage
The resource module provides tools for measuring and controlling system resources used by a program.
Use it to query resource usage (CPU time, memory), set resource limits, or monitor system resource consumption on Unix systems.
Note: This module is only available on Unix/Linux systems. It is not available on Windows.
