程序开始处的Python函数调用

Question

我是python的新手，并且相信对此有一个简单的答案，但似乎无法弄清楚。在此程序的开头是否可以进行函数调用。如您所见，我正在运行代码，然后要求再次运行它，这是它现在执行函数调用的位置。这按原样工作，但我希望摆脱while循环和函数之外的所有内容，以便清理代码。谢谢。

import subprocess

import re

print ("This will print any service that is stopped or unknown \n")

#servers

server = str(input("Enter server to query(IP Address): "))

server_list = server.split(",")

server_count = len(server_list)

#services

service = str(input("Enter service to query: "))

service_list = service.split(",")

service_count = len(service_list)

#server loop

for a in range(len(server_list)):

  server_net_use = 'net use'+r' \\'+server_list[a]+r'\ipc$ /user:Administrator itv'

  server_disconnect = 'net use'+r' \\'+server_list[a]+r'\ipc$ /d'

  server_sc = r'\\'+server_list[a]

  subprocess.check_output(server_net_use, universal_newlines=True)

#service loop

  for i in range(len(service_list)):

    x = subprocess.check_output(['sc', server_sc, 'query', service_list[i]], universal_newlines=True)

    y = re.sub('\s+',' ',x)

    if 'FAILED' in y:

      print ('\n'+server_list[a]+' - '+service_list[i]+' - Unknown Service!')

    elif 'STOPPED' in y:

      print ('\n'+server_list[a]+' - '+service_list[i]+' - '+y.split(" ")[10])

def repeat():

  #servers

  server = str(input("Enter server to query(IP Address): "))

  server_list = server.split(",")

  server_count = len(server_list)

  #services

  service = str(input("Enter service to query: "))

  service_list = service.split(",")

  service_count = len(service_list)

#server loop

  for a in range(len(server_list)):

    server_net_use = 'net use'+r' \\'+server_list[a]+r'\ipc$ /user:Administrator itv'

    server_disconnect = 'net use'+r' \\'+server_list[a]+r'\ipc$ /d'

    server_sc = r'\\'+server_list[a]

    subprocess.check_output(server_net_use, universal_newlines=True)

这是这样的：import subprocessimport redef server_checker():    print ("This will print any service that is stopped or unknown \n")    #servers    server = str(input("Enter server to query(IP Address): "))    server_list = server.split(",")    server_count = len(server_list)    #services    service = str(input("Enter service to query: "))    service_list = service.split(",")    service_count = len(service_list)    #server loop    for a in range(len(server_list)):        server_net_use = 'net use'+r' \\'+server_list[a]+r'\ipc$ /user:Administrator itv'        server_disconnect = 'net use'+r' \\'+server_list[a]+r'\ipc$ /d'        server_sc = r'\\'+server_list[a]        subprocess.check_output(server_net_use, universal_newlines=True)    #service loop    for i in range(len(service_list)):      x = subprocess.check_output(['sc', server_sc, 'query', service_list[i]], universal_newlines=True)      y = re.sub('\s+',' ',x)      if 'FAILED' in y:        print ('\n'+server_list[a]+' - '+service_list[i]+' - Unknown Service!\n')      elif 'STOPPED' in y:        print ('\n'+server_list[a]+' - '+service_list[i]+' - '+y.split(" ")[10]+'\n')if __name__ == "__main__":           server_checker()    while(True):        answer = str(input("Do you want to query another service? y/n: "))        if answer.lower() in ["yes","y","letsgo"]:          subprocess.check_output(server_disconnect, universal_newlines=True)          print ("\n")          server_checker()        elif answer.lower() in ["no","n,","nowayhosay"]:          subprocess.check_output(server_disconnect, universal_newlines=True)          break;        else:          print ('Enter y/n')
