<p>我正在尝试使用以下代码:</p>
<pre><code>for x in story:
var1 = str(x)
var1 = var1.replace("<p>", "\n")
var1 = var1.replace("</p>", "")
story[x] = var1
</code></pre>
<p>删除段落标记,并插入换行符,然后将它们重新插入变量中。字符串如下:</p>
<pre><code>Panera Bread (NASDAQ: <a class="ticker" href="/stock/pnra#NASDAQ">PNRA</a>) is down 6 percent today over expectations of food inflation of 4.5% in Q3 and 5% for Q4. In addition, Panera Will Raise Menu Prices in Q4.
PNRA recently posted second quarter 2011 earnings of $1.18 per share. Reported earnings also outpaced the prior-year quarter earnings of 85 cents per share.
But shares were also lower ahead of the opening bell after the company reported weaker-than-expected same-store sales figures for its recent quarter late Tuesday. Its profit of $1.18 a share topped analysts' consensus call by a penny.
For the twenty-six weeks ended June 28, 2011, net income was $68 million, or $2.27 per diluted share. These results compare to net income of $53 million, or $1.67 per diluted share, for the twenty-six weeks ended June 29, 2010, and represent a 36% year-over-year increase in diluted earnings per share.

<p>我收到的错误消息是:</p>
<pre><code>Traceback (most recent call last):
