psutil

psutil enables Python developers to programmatically access comprehensive system and process information through a clean, cross-platform API. The library provides detailed metrics about system resources such as CPU load, memory allocation, disk usage, network activity, and battery status. It also offers extensive process management capabilities including process enumeration, termination, and detailed process attribute retrieval. By abstracting away platform differences, psutil allows developers to write system monitoring code that works consistently across different operating systems, making it an essential tool for system administrators and application developers alike.
