python - Parsing HTML with BeautifulSoup

enter image description here

(Picture is small, here is another link: http://i.imgur.com/OJC0A.png)

I'm trying to extract the text of the review at the bottom. I've tried this:

y = soup.find_all("div", style = "margin-left:0.5em;")
review = y[0].text

The problem is that there is unwanted text in the unexpanded div tags that becomes tedious to remove from the content of the review. For the life of me, I just can't figure this out. Could someone please help me?

Edit: The HTML is:

div style="margin-left:0.5em;">
    <div style="margin-bottom:0.5em;"> 9 of 35 people found the following review helpful </div>
    <div style="margin-bottom:0.5em;">
    <div style="margin-bottom:0.5em;">
    <div class="tiny" style="margin-bottom:0.5em;">
        <b>
    </div>
    That is true. I tried it myself this morning. There's a little note on the Audible site that says "a few titles will require two credits" or something like that. A Dance with Dragons is one of those few. 

The div tag above the text is as follows:

<div class="tiny" style="margin-bottom:0.5em;">
    <b>
        <span class="h3color tiny">This review is from: </span>
        <a href="https://rads.stackoverflow.com/amzn/click/com/B005C7QVUE" rel="nofollow noreferrer">A Dance with Dragons: A Song of Ice and Fire: Book 5 (Audible Audio Edition)</a>
    </b>
</div>

http://www.crummy.com/software/BeautifulSoup/bs4/doc/#strings-and-stripped-strings suggests that the .strings method is what you want - it returns a iterator of each string within the object. So if you turn that iterator into a list and take the last item, you should get what you want. For example:

$ python
>>> import bs4
>>> text = '<div style="mine"><div>unwanted</div>wanted</div>'
>>> soup = bs4.BeautifulSoup(text)
>>> soup.find_all("div", style="mine")[0].text
u'unwantedwanted'
>>> list(soup.find_all("div", style="mine")[0].strings)[-1]
u'wanted'
