How to access accessors in python Class

I am trying to access the accessor getSentence() however I am getting the error that 

AttributeError: 'Sentence' object has no attribute '_string'

I looked at many libraries and they said the right way to return it is with 

self._

Here is my code:

class Sentence:
    def __init__(self, string):
        self.string = string
    def getSentence(self):
        return self._string
    def getWords(self):
        return self._aList
    def getLength(self):
        return len(self._string)
    def getNumWords(self):
        return len(self._string.split())


hippo = Sentence("hello world")
hippo.getSentence()

In __init__ you assign to self.string, not self._string. Simply correct that to self._string or rename the attribute you access in getSentence() to self.string.

That said, you don't really need an accessor here. If you leave the name as string, you can just use hippo.string and be done with it. Accessors are not really that useful if all they do is return the value of an attribute.
