Hello, I need the cpu usage of a linux box, for which i capture the output of "top" using "popen". However, i am facing problems during string handling. The code snippet is:-
top = os.popen("top -n 1") rd = top.read().split("\n") splt = rd[2].split() # cpu = splt[2][:-4] # why ain't this working ??? cpu = splt[2] print "cpu usage: %s, %s" % (cpu, type(cpu)) the "print" statement prints, "cpu usage: 0.5%sy, <type 'str'>". i tried my best to get rid of the "%sy" after the "0.5", but couldn't succeed (even though the type of "cpu" is "string"). Also, one weird thing that was happening was that if i still "split" the cpu string (removed the last 4 characters), the output of the next print statement was wrong (specifically, the first 2 characters got chipped off). This output is totally unexpected, and wrong... Can anyone kindly help me in understanding what exactly is going on here. Thanks a lot! -- http://mail.python.org/mailman/listinfo/python-list
