为什么此代码不会在Python中删除我的反斜杠？

Question

我有一段代码是字符串格式的。它的变量名my_string如下所示：

'<div class="section page-centered"><div><b style="font-size: 24px">About 
Us</b></div><div>At <a href="https://close.com/" class="postings- 
link">Close</a>, we\'re building the sales
communication platform of the future. With our roots as the very first 
sales CRM to include built-in calling, we\'re leading the industry toward 
eliminating manual processes and helping compa
nies to close more deals (faster). Since our founding in 2013, we\'ve 
grown to become a profitable, 100% globally distributed team of ~33 high- 
performing, happy people that are dedicated to b
uilding a product our customers love. </div>'

除了反斜杠，我想将所有内容保留在该块中。我在这里看到了很多问题和解答，哪里可以找到解决方案

new_string = my_string.replace("\\", "")

但是我得到相同的输出。我在这里做什么错了？

Answer 1

反斜杠实际上是在转义单引号。如果我打印字符串，我将得到：

print('<div class ... </div>')

<div class="section page-centered"><div><b style="font-size: 24px">About Us</b></div><div>At <a href="https://close.com/" class="postings- link">Close</a>, we're building the salescommunication platform of the future. With our roots as the very first sales CRM to include built-in calling, we're leading the industry toward eliminating manual processes and helping companies to close more deals (faster). Since our founding in 2013, we've grown to become a profitable, 100% globally distributed team of ~33 high- performing, happy people that are dedicated to building a product our customers love. </div>

Answer 2

我不确定为什么它可以在某些计算机上运行，​​但是至少在我的系统中存在此问题：

• 后跟某事的强烈反对实际上不是双重反对，除非它是双重反对：

为

back_lash="hi\myname\is\backlash"
print(back_lash)

这将输出：

hi\myname\iacklash

在可以为其着色的IDE中更容易看到它。

如您所见，它是一个非常特殊的字符。替换为双反冲

如here中所述，它很难解决反弹问题。反斜杠（“ \”）字符用于转义具有特殊含义的字符，例如换行符，反斜杠本身或引号字符。 您可以使用前缀r或R：

字符串文字可以选择以字母'r'或'R'为前缀；这样的字符串称为原始字符串，并使用不同的规则来解释反斜杠转义序列。

r"Some string with \ backslash"

看看this，他们提到：

  

您需要在反斜杠前面加上另一个反斜杠   反斜杠\字符称为转义字符，它以不同的方式解释其后的字符。例如，n本身只是一个字母，但是当您在其前加反斜杠时，它变为\ n，这是换行符。

您可能会猜到，\也需要转义，因此它不像转义符那样起作用。本质上，您必须...逃脱。
