如何使用python取统计每个用户的进程数

os.system() 调用系统命令
popen() 调用系统命令 将结果存入文件对象

import os
fobj = os.popen('ps -aux')
count = {}
with fobj as f:
    for i in f.readlines():
       # print(i.split(' '))
        if i.split(' ')[0]in count:
            count[i.split(' ')[0]] += 1
        else:
            count[i.split(' ')[0]] = 1
if 'USER'in count:
    del count['USER']

print(count)
