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：

方式二：
import win32pdh, string, win32api
def procids():
#each instance is a process, you can have multiple processes w/same name
junk, instances = win32pdh.EnumObjectItems(None,None,'process', win32pdh.PERF_DETAIL_WIZARD)
proc_ids=[]
proc_dict={} for instance in instances: if instance in proc_dict:
proc_dict[instance] = proc_dict[instance] + 1
else:
proc_dict[instance]=0
for instance, max_instances in proc_dict.items(): for inum in xrange(max_instances+1):
hq = win32pdh.OpenQuery() # initializes the query handle
path = win32pdh.MakeCounterPath( (None,'process',instance, None, inum,'ID Process') )
counter_handle=win32pdh.AddCounter(hq, path)
win32pdh.CollectQueryData(hq) #collects data for the counter
type, val = win32pdh.GetFormattedCounterValue(counter_handle, win32pdh.PDH_FMT_LONG)
proc_ids.append((instance,str(val)))
win32pdh.CloseQuery(hq)
proc_ids.sort() return proc_ids
print procids()运行结果：

进程名，进程Id元组的列表
方式三：

通过交互模式，使用WMI取得进程：

此方法可以跨平台，不过需要在安装psutil包.
import osimport psutilimport time
logPath = r'some\path\proclogs'if not os.path.exists(logPath):
os.mkdir(logPath)
separator = "-" * 80format = "%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。
