I’m in the same boat sailing from Bash Basin to Python Peninsula. I had to use a series of xrandr and wmctrl commands piped through grep for my inaugural project (still on-going sigh). Your solution would be:
$ sensors | grep Core
Core 0: +47.0°C (high = +100.0°C, crit = +100.0°C)
Core 1: +49.0°C (high = +100.0°C, crit = +100.0°C)
Core 2: +45.0°C (high = +100.0°C, crit = +100.0°C)
Core 3: +47.0°C (high = +100.0°C, crit = +100.0°C)
$ sensors.py
49
51
47
48
Here’s your script:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import os
list_cores = os.popen("sensors | grep Core").read().splitlines()
for l in list_cores:
# Core 0: +47.0°C (high = +100.0°C, crit = +100.0°C) <---- sample
# ^ ^
# | |
# | +---- 2md split on decimal take [0] element (b list)
# +------- 1st aplit on plus sign take [1] element (a list)
a = l.split("+")
b = a[1].split(".")
c = b[0]
print (c)
Mark as executable before running: chmod a+x sensors.py
Happy to answer any questions :)
