python
import psutil

unallocated_space = get_unallocated_space(drive)
if unallocated_space is not None:
print(f"Unallocated space on {drive}: {unallocated_space / (1024**3)} GB")
else:
print(f"Drive {drive} not found or unallocated space information is not available.")


This code uses the `psutil` library to get disk partitions and their usage information. By specifying the desired drive letter or path, you can retrieve the unallocated space on that drive. The result is then displayed in gigabytes (GB).
