Fastest way to get system uptime in Python in Linux

Question

I\'m looking for a fast and lightweight way to read system uptime from a Python script. Is there a way to call the sysinfo Linux system call from Python?

Answer 1

Adding an UP TO DATE answer.

This may not be the fastest way. But this is should be the replacement for psutil.boot_time() since I couldn't find boot_time in latest versions of linux psutil lib.

Dependancy:

pip3 install uptime

Usage:

>>> from uptime import uptime
>>> uptime()
49170.129999999997
