1.Python输出中文

#!/usr/bin/python

#coding:utf-8

2.Python %s %r的区别

The %s specifier converts the object using str(), and %r converts it using repr().

For some objects such as integers, they yield the same result, but repr() is special in that (for types where this is possible) it conventionally returns a result that is valid Python syntax, which could be used to unambiguously recreate the object it represents.

Here's an example, using a date:

>>> d = datetime.date.today()

>>> str(d)

'2011-05-14'

>>> repr(d)

'datetime.date(2011, 5, 14)'

Types for which repr() doesn't produce Python syntax include those that point to external resources such as a file, which you can't guarantee to recreate in a different context.
