Question

python根据进程pid获取进程cpu等信息时出错

p.cpu_percent(interval=0.1)这个函数有延时么,每次调用的时候特别慢

Answer 1

import psutilimport reimport sysdef processinfo(x):
                    p = 如喊答psutil.get_process_list()
                    渗举for r in p:
                        aa = str(r)
                        f = re.compile(x,re.I)
                        if f.search(aa):
                    渣慧#        print aa.split('pid=')[1].split(',')[0]  
                             print aa.split('pid=')processinfo(sys.argv[1])
