Question

我正在使用python 2.7和windows。我想找出进程名称时活动的进程ID列表。

import time
import win32pdh
def GetProcessID( name ) :
    object = "Process"
    items, instances = win32pdh.EnumObjectItems( None, None, object,
                                                 win32pdh.PERF_DETAIL_WIZARD )
    val = None
    if name in instances :
        hq = win32pdh.OpenQuery()
        hcs = [ ]
        item = "ID Process"
        path = win32pdh.MakeCounterPath( ( None, object, name, None, 0, item ) )
        hcs.append( win32pdh.AddCounter( hq, path ) )
        win32pdh.CollectQueryData( hq )
        time.sleep( 0.01 )
        win32pdh.CollectQueryData( hq )

        for hc in hcs:
            type, val = win32pdh.GetFormattedCounterValue( hc, win32pdh.PDH_FMT_LONG )
            win32pdh.RemoveCounter( hc )
        win32pdh.CloseQuery( hq )
        return val
hh=GetProcessID("python")

在上面的代码中，即使两个python进程正在运行，我也只获得了一个进程ID。我的查询如何使用python进程激活所有进程ID

Answer 1

您可以使用psutil获取此信息：

import psutil

NoNameAccesses = []
for p in psutil.process_iter():
   try: 
      if p.name.startswith('python'):
          print (p.name, p.pid)
   except psutil._error.AccessDenied:
       # Handle where the user does not have permission to get the name 
       NoNameAccesses.append(p.pid)

if len(NoNameAccesses) > 0:
    print ("Warning: You don't have access to he following processes:")
    print (NoNameAccesses)

您可以尝试调用“tasklist”并处理输出。
