检查Python中是否存在Windows服务

我用python编写了一个与Windows服务交互的程序。但是，在执行此操作之前，我需要检查服务是否已安装

我正在使用以下代码来获取服务。但如果它不存在，我会收到错误

win32serviceutil.QueryServiceStatus('myservice')

这是错误：

Traceback (most recent call last):
  File "win32serviceutil.pyc", line 835, in SvcRun
  File "main.py", line 54, in SvcDoRun
  File "main.py", line 103, in main
  File "main.py", line 57, in start_service
  File "main.pyc", line 495, in QueryServiceStatus
  File "main.pyc", line 80, in SmartOpenService
error: (1060, 'GetServiceKeyName', 'The specified service does not exist as an installed service')

有什么方法可以检查它吗？

除了试块之外，它似乎是最简单的解决方案：

try: 
    win32serviceutil.QueryServiceStatus('myservice')
except:
    print "Windows service NOT installed"
else:
    print "Windows service installed"

可通过以下方式完成：

代码如下：

from __future__ import print_function
import psutil

def get_service(name):
    service = None
    try:
        service = psutil.win_service_get(name)
        service = service.as_dict()
    except Exception as ex:
        # raise psutil.NoSuchProcess if no service with such name exists
        print(str(ex))

    return service

service = get_service('LanmanServer')

if service:
    print("Service found: ", service)
else:
    print("Service not found")

if service and service['status'] == 'running':
    print("Service is running")
else: 
    print("Service is not running")

@据我所知，达夫马特的回答非常优雅，而且很像蟒蛇，它回答了你的问题。如果你不这么认为，也许你应该重新制定你的问题，更具体地告诉你在寻找什么。
