如何获取Raspberry Pi B温度作为Python3变量？

Question

Is there any way to get the temperature of a Raspberry Pi, specifically the B model as a Python3 variable.

The current OS is Raspbian.

I do not have the onboard Sensor on my RPi, but according to this thread , you require this line: /opt/vc/bin/vcgencmd measure_temp

Keep in mind that this doesn't provide a float (as I had previously thought). However, you can use the subprocess module to acquire the data and format/strip it from there:

import subprocess
temp = subprocess.check_output(["/opt/vc/bin/vcgencmd measure_temp | cut -c6-9"], shell=True)[:-1]

I have read that using subprocess.Popen() is a better approach - failed to find out why though (perhaps someone else can elaborate on this?).

It would look something like this:

tmp = subprocess.Popen(["/opt/vc/bin/vcgencmd", "measure_temp"], stdout=subprocess.PIPE)

You can read up more on the subprocess module here .

Edit : I've updated the code; I recently found a pyscript returning the temperature of the RPi.
