System Information Tool
This utility gathers and displays detailed information about the system hardware and operating system. It demonstrates how to use the standard platform module for OS details and the powerful third-party psutil library for hardware utilization stats.
Modules Used:
- platform: To retrieve operating system and processor information.
psutil: To retrieve CPU, memory, and disk usage statistics.
Installation
You will need to install psutil:
pip install psutilThe Code
Save this as sysinfo.py.

Scale bytes to its proper format
e.g:

"""

for unit in ["", "K", "M", "G", "T", "P"]:

return f"{bytes:.2f}{unit}{suffix}"
