python - Python：将列表分配给函数

问题描述

有没有办法根据变量 env 分配一个列表并将结果传递给函数？我正在传递一个名为 env 的变量，例如，它可以是 UPE、DEV、PRD。根据结果​​，我想将列表分别分配给下面的函数。最好的方法是什么？

UPE=['SERVER1','SERVER2','SERVER3','SERVER4']
DEV=['ServerA','ServerB']
PRD=['SERVER1','SERVER2','SERVER3','SERVER4']

if os.path.isfile('/myfile/' + configFile):

  config_parser = ConfigParser()
  config_parser.read('/myfile/' + configFile)

if actions == "start":
    startOVD('start',UPE[3]) //I want pass the result of env setup variable
    #ans = raw_input("Would you like to start OVD, MSAS,OAG : y | n : ")
    if env == 'UPE':
        startMSAS('start',UPE[0])
        startOAG('start',UPE[1])
    startOHS('start',UPE[2])
    for section_name in sorted(config_parser.sections(), reverse=True):
        adminURL = config_parser.get(section_name, 'ADMIN_URL')
        adminUsername = config_parser.get(section_name, 'ADMIN_USER')
        adminPassword = config_parser.get(section_name, 'ADMIN_PASS')
        adminHost = config_parser.get(section_name, 'NM_HOST')
        domainName = config_parser.get(section_name, 'DOMAIN_NAME')
        domainDir = config_parser.get(section_name, 'DOMAIN_DIR')
        admPort = adminURL[-4:]

        printHeader('Initiating Starting Sequence')
        startAdmin('start', adminHost, domainDir, domainName, admPort)
        showServerStatus('start', adminUsername, adminPassword, adminURL)


if actions == "stop":
    for section_name in (config_parser.sections()):
        adminURL = config_parser.get(section_name, 'ADMIN_URL')
        adminUsername = config_parser.get(section_name, 'ADMIN_USER')
        adminPassword = config_parser.get(section_name, 'ADMIN_PASS')
        adminHost = config_parser.get(section_name, 'NM_HOST')
        domainName = config_parser.get(section_name, 'DOMAIN_NAME')
        domainDir = config_parser.get(section_name, 'DOMAIN_DIR')
        admPort = adminURL[-4:]

        printHeader('Initiating Stopping Sequence')
        showServerStatus('stop', adminUsername, adminPassword, adminURL)
        stopAdmin(adminHost, domainDir, domainName, admPort)

    if env == 'UPE':
        stopMSAS('stop',UPE[0])
        stopOAG('stop',UPE[1])
    stopOHS('stop',UPE[2])
    stopOVD('stop',UPE[3])

解决方案

我会通过设置回调列表来组织它。

from functools import partial

start_funcs = [partial(startOVD 'start',UPE[3])
if env == 'UPE':
    start_funcs.extend([partial(startMSAS, 'start', UPE[0]),
                       partial(startOAG, 'start', UPE[1])])
start_funcs.append(partial(startOHS, 'start', UPE[2]))

env为具有不同值的情况添加类似的逻辑。最后，您只需迭代start_funcs并按顺序调用每个函数。

if actions == "start":
    for f in start_funcs:
        f()

    # ...
