The <a href="http://docs.python.org/library/cgi.html#functions" rel="nofollow noreferrer">cgi.escape</a> method will convert special charecters to valid html tags

<pre><code> import cgi
 original_string = 'Hello "XYZ" this \'is\' a test &amp; so on '
 escaped_string = cgi.escape(original_string, True)
 print original_string
 print escaped_string
</code></pre>

will result in

<pre><code>Hello "XYZ" this 'is' a test &amp; so on 
Hello &amp;quot;XYZ&amp;quot; this 'is' a test &amp;amp; so on 
</code></pre>

The optional second paramter on cgi.escape escapes quotes. By default, they are not escaped

blocks|key|1357781|text|一个简单的字符串函数就可以做到这一点：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1357782|def+escape(t):

A simple string function will do it:

<pre><code>def escape(t):
 """HTML-escape the text in `t`."""
 return (t
 .replace("&amp;", "&amp;amp;").replace("&lt;", "&amp;lt;").replace("&gt;", "&amp;gt;")
 .replace("'", "&amp;#39;").replace('"', "&amp;quot;")
 )
</code></pre>

Other answers in this thread have minor problems: The cgi.escape method for some reason ignores single-quotes, and you need to explicitly ask it to do double-quotes. The wiki page linked does all five, but uses the XML entity <code>&amp;apos;</code>, which isn't an HTML entity.

This code function does all five all the time, using HTML-standard entities.

blocks|key|1357836|text|这里的其他答案将对您列出的字符和其他一些字符有所帮助。但是，如果您还希望将其他所有内容也转换为实体名称，则必须执行其他操作。例如，如果需要将á转换为&aacute;，那么cgi.escape和html.escape都不能帮助您实现这一点。您可能想要使用html.entities.entitydefs来做类似的事情，它只是一个字典。(下面的代码是为Python+3.x编写的，但为了让您有所了解，我们尝试让它与2.x兼容)：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1357837|#+-*-+coding:+utf-8+-*-

The other answers here will help with such as the characters you listed and a few others. However, if you also want to convert everything else to entity names, too, you'll have to do something else. For instance, if <code>á</code> needs to be converted to <code>&amp;aacute;</code>, neither <code>cgi.escape</code> nor <code>html.escape</code> will help you there. You'll want to do something like this that uses <code>html.entities.entitydefs</code>, which is just a dictionary. (The following code is made for Python 3.x, but there's a partial attempt at making it compatible with 2.x to give you an idea):

<pre><code># -*- coding: utf-8 -*-

import sys

if sys.version_info[0]&gt;2:
 from html.entities import entitydefs
else:
 from htmlentitydefs import entitydefs

text=";\"áèïøæỳ" #This is your string variable containing the stuff you want to convert
text=text.replace(";", "$ஸ$") #$ஸ$ is just something random the user isn't likely to have in the document. We're converting it so it doesn't convert the semi-colons in the entity name into entity names.
text=text.replace("$ஸ$", "&amp;semi;") #Converting semi-colons to entity names

if sys.version_info[0]&gt;2: #Using appropriate code for each Python version.
 for k,v in entitydefs.items():
 if k not in {"semi", "amp"}:
 text=text.replace(v, "&amp;"+k+";") #You have to add the &amp; and ; manually.
else:
 for k,v in entitydefs.iteritems():
 if k not in {"semi", "amp"}:
 text=text.replace(v, "&amp;"+k+";") #You have to add the &amp; and ; manually.

#The above code doesn't cover every single entity name, although I believe it covers everything in the Latin-1 character set. So, I'm manually doing some common ones I like hereafter:
text=text.replace("ŷ", "&amp;ycirc;")
text=text.replace("Ŷ", "&amp;Ycirc;")
text=text.replace("ŵ", "&amp;wcirc;")
text=text.replace("Ŵ", "&amp;Wcirc;")
text=text.replace("ỳ", "&amp;#7923;")
text=text.replace("Ỳ", "&amp;#7922;")
text=text.replace("ẃ", "&amp;wacute;")
text=text.replace("Ẃ", "&amp;Wacute;")
text=text.replace("ẁ", "&amp;#7809;")
text=text.replace("Ẁ", "&amp;#7808;")

print(text)
#Python 3.x outputs: &amp;semi;&amp;quot;&amp;aacute;&amp;egrave;&amp;iuml;&amp;oslash;&amp;aelig;&amp;#7923;
#The Python 2.x version outputs the wrong stuff. So, clearly you'll have to adjust the code somehow for it.

I have a string where special characters like <code>'</code> or <code>"</code> or <code>&amp;</code> (...) can appear. In the string:

<pre><code>string = """ Hello "XYZ" this 'is' a test &amp; so on """
</code></pre>

how can I automatically escape every special character, so that I get this:

<pre><code>string = " Hello &amp;quot;XYZ&amp;quot; this &amp;#39;is&amp;#39; a test &amp;amp; so on "
</code></pre>
