how to escape/unescape?

python里面怎么实现javascript的escape和unescape的功能？

try escape(data[, entities]) and unescape(data[, entities]) in module xml.sax.saxutils

好像不行。
javascript的escape把一些字符都变成%NN的形式，例如空格是%20
而xml.sax.saxutils得escape不是这样的。

xml.sax.saxutils
escape( data[, entities])

Escape "&", "<", and ">" in a string of data.
You can escape other strings of data by passing a dictionary as the optional entities parameter. The keys and values must all be strings; each key will be replaced with its corresponding value.

是这样啊，那得用urllib的quote和unquote

谢谢。
原来不同的lib术语不一样，javascript里面叫escape/unescape, urllib里面叫quote/unquote，难怪查不到的。术语关键字不一样，这是个问题。
