python:根据进程名获取主窗口句柄

具体运行性能暂不考虑，作为一种思路保存。代码如下：

import time
import psutil
from win32 import win32gui
from win32 import win32api
from win32 import win32process
strCmd="cmd.exe"
#map类型，键值为进程ID,value为窗口句柄。
mID2Handle={}
def get_all_hwnd(hwnd,mouse):
  if win32gui.IsWindow(hwnd) and win32gui.IsWindowEnabled(hwnd) and win32gui.IsWindowVisible(hwnd):
    nID=win32process.GetWindowThreadProcessId(hwnd)
    #print(nID,win32gui.GetWindowText(hwnd))
    del nID[0]
    for abc in nID:
      try:
        pro=psutil.Process(abc).name()
      except psutil.NoSuchProcess:
        pass
      else:
        #print(abc,win32gui.GetWindowText(hwnd))
        if pro == strCmd:
          print("进程ID：",abc,"窗口句柄: ",hwnd,"标题: ",win32gui.GetWindowText(hwnd))
          mID2Handle[abc]=hwnd
win32gui.EnumWindows(get_all_hwnd, 0)
