在Python中进行不区分大小写字符串比较的最好方法是什么？

What's the best way to do case insensitive string comparison in Python?

我想将一个常规字符串与一个存储库字符串进行比较，和pythonic方式。我也想有能力在字符串使用普通的python字符串中查找字符串中的值。

I would like to encapsulate comparison of a regular strings to a repository string using in a very simple and pythonic way. I also would like to have ability to look up values in a dict hashed by strings using regular python strings. Much obliged for advice.

假设ASCII字符串：

Assuming ASCII strings:

string1 = 'Hello' string2 = 'hello' if string1.lower() == string2.lower(): print "The strings are the same (case insensitive)" else: print "The strings are not the same (case insensitive)"
