简化if - if阶梯 - python

Question

我需要将这些代码行简化为小于4的if.不知道我怎么能做到这一点:

    for response in response_json:
        for appliance in response['versanms.ApplianceStatusResult']['appliances']:
            temp_item = OrderedDict()
            if 'name' in appliance:
                temp_item['name'] = appliance['name']
            if 'type' in appliance:
                temp_item['type'] = appliance['type']
            if 'ping-status' in appliance:
                temp_item['ping-status'] = appliance['ping-status']
            if 'sync-status' in appliance:
                temp_item['sync-status'] = appliance['sync-status']
            if 'services-status' in appliance:
                temp_item['services-status'] = appliance['services-status']
            if 'orgs' in appliance:
                temp_item['orgs'] = appliance['orgs']
            if 'ownerOrg' in appliance:
                temp_item['ownerOrg'] = appliance['ownerOrg']
            if 'softwareVersion' in appliance:
                temp_item['softwareVersion'] = appliance['softwareVersion']
            if 'ipAddress' in appliance:
                temp_item['ipAddress'] = appliance['ipAddress']
            if appliance is not None:
                appliance_list.insert(0, temp_item)
return {'appliance': appliance_list}

需要删除if's,因为我们的代码验证工具不喜欢超过4,如果在一个方法中:(

谢谢

替换所有这些:

if 'name' in appliance:
    temp_item['name'] = appliance['name']
if 'type' in appliance:
    temp_item['type'] = appliance['type']
if 'ping-status' in appliance:
    temp_item['ping-status'] = appliance['ping-status']
if 'sync-status' in appliance:
    temp_item['sync-status'] = appliance['sync-status']
if 'services-status' in appliance:
    temp_item['services-status'] = appliance['services-status']
if 'orgs' in appliance:
    temp_item['orgs'] = appliance['orgs']
if 'ownerOrg' in appliance:
    temp_item['ownerOrg'] = appliance['ownerOrg']
if 'softwareVersion' in appliance:
    temp_item['softwareVersion'] = appliance['softwareVersion']
if 'ipAddress' in appliance:
    temp_item['ipAddress'] = appliance['ipAddress']

循环:

for x in ['name', 'type', 'ping-status', 'sync-status',
          'services-status', 'orgs', 'ownerOrg',
          'softwareVersion', 'ipAddress']:
    if x in appliance:
        temp_item[x] = appliance[x]
