返回列表函數python

Question

我是python的新手，我正在下面的q嘗試此代碼。Objects1返回列表

我怎樣才能做到這一點？

它返回以下錯誤

文件“ / home / paulo / Desktop / testepy2 / objectMIB.py”，第53行返回SyntaxError：函數外部返回“ return”

謝謝

               MibObject('MY-MIB', 'testCount', mib.getTestCount),MibObject('MY-MIB', 'testGet', mib.getTestGet), MibObject('MY-MIB', 'testSet', mib.getTestSet) ]

    print objects1
    return

嵌套在“ ListObejtc ”中的代碼顯示在方法中是正常的，如下所示：

class ListObejtc ():
    def __init__(self):
        pass

    def doObjects(self):
        mib = objectMIB.Mib()
        objects1 = [MibObject('MY-MIB', 'testDescription', mib.getTestDescription),
               MibObject('MY-MIB', 'testCount', mib.getTestCount),MibObject('MY-MIB', 'testGet', mib.getTestGet), MibObject('MY-MIB', 'testSet', mib.getTestSet) ]

        print objects1
        return objects1 

之所以會出現SyntaxError是因為return與類上下文中的內容相同，在那兒沒有意義。
