You can get this info with
top -b -n 1
Then you can awk, grep or pythonize the output to get whatever you need

However, I do not recommend this method as it is both slow and heavy in 
resources usage. Furthermore, those CPU loads are instantaneous values 
that represent only 1 second (or any delay top uses to compute those 
numbers), and thus can be aberrant regarding what the CPU has during all 
the time it was not checked for; i.e. if your check_interval is 5 
minutes you should not take a random, 1 second long sample in a 5 min 
period but an average value computed over the 5 minutes.

Have a look check_snmp_load.pl and its *netsc *option for the -T 
argument (see http://www.manubulon.com/nagios/snmp_load.html)
This might be what you are looking for.
