用python获得正在的运行的windows进程的有几种方式:

方式一

通过 PyWin32包对Windows进行处理。
可以通过这个获取系统信息，但仅限于windows系统。

import win32com.client
wmi=win32com.client.GetObject('winmgmts:')
for p in wmi.InstancesOf('win32_process'):
    print p.Name, p.Properties_('ProcessId'), \
        int(p.Properties_('UserModeTime').Value)+int(p.Properties_('KernelModeTime').Value)
    children=wmi.ExecQuery('Select * from win32_process where ParentProcessId=%s' %p.Properties_('ProcessId'))
    for child in children:
        print '\t',child.Name,child.Properties_('ProcessId'), \
            int(child.Properties_('UserModeTime').Value)+int(child.Properties_('KernelModeTime').Value)

运行结果：

方式四:

此方法可以跨平台，不过需要在安装psutil包.

import os
import psutil
import time
 
logPath = r'some\path\proclogs'
if not os.path.exists(logPath):
    os.mkdir(logPath)
 
separator = "-" * 80
format = "%7s %7s %12s %12s %30s, %s"
format2 = "%7.4f %7.2f %12s %12s %30s, %s"
while 1:
  # psutil.get_process_list() 方法已经废弃，可以使用psutil.process_iter()迭代器

    procs = psutil.get_process_list()
    procs = sorted(procs, key=lambda proc: proc.name)
 
    logPath = r'some\path\proclogs\procLog%i.log' % int(time.time())
    f = open(logPath, 'w')
    f.write(separator + "\n")
    f.write(time.ctime() + "\n")
    f.write(format % ("%CPU", "%MEM", "VMS", "RSS", "NAME", "PATH"))
    f.write("\n")
 
    for proc in procs:
        cpu_percent = proc.get_cpu_percent()
        mem_percent = proc.get_memory_percent()
        rss, vms = proc.get_memory_info()
        rss = str(rss)
        vms = str(vms)
        name = proc.name
        path = proc.path
        f.write(format2 % (cpu_percent, mem_percent, vms, rss, name, path))
        f.write("\n\n")
    f.close()
    print "Finished log update!"
    time.sleep(300)
    print "writing new log data!"

以上实现一个类似top的工具。
