字符串简单替换(String Simple Substitution)

 我将大多数用户使用的简单正则表达式格式转换为正确的re python正则表达式字符串的最简单方法是什么？  
 作为一个例子，我需要转换这个：  
string = "*abc+de?"
 
 对此：  
string = ".*abc.+de.?"
 
 当然，我可以遍历字符串并按字符构建另一个字符串，但这肯定是一种低效的方法吗？ 

What's the easiest way of me converting the simpler regex format that most users are used to into the correct re python regex string? 
As an example, I need to convert this: 
string = "*abc+de?"
 
to this: 
string = ".*abc.+de.?"
 
Of course I could loop through the string and build up another string character by character, but that's surely an inefficient way of doing this?
