How to use a regexp here

[Cecil Westerhof]

I have a script that was running perfectly for some time. It uses:
    array = [elem for elem in output if 'CPU_TEMP' in elem]

But because output has changed, I have to check for CPU_TEMP at the beginning
of the line. What would be the best way to implement this?
