python 如何将字符串转换成列表
如何将字符串如`a = "我是中国人"`，转换成列表`li =["我","是","中","国","人"]`
```
a = "我是一个中国人"
li = list(a)
print li
```
输出却是
```
['\xe6', '\x88', '\x91', '\xe6', '\x98', '\xaf', '\xe4', '\xb8', '\x80', '\xe4', '\xb8', '\xaa', '\xe4', '\xb8', '\xad', '\xe5', '\x9b', '\xbd', '\xe4', '\xba', '\xba']
```
我用JavaScript很简单的就实现了
```
var a = "我是中国人"
li = a.split("")
console.log(li) // >>>["我","是","中","国","人"]
```
不知道python应该如何实现？
可以先将字符串解编码成`unicode`, 再用`list`
```
# 第一种:
>>> a = u"我是中国人"
>>> s = list(a)
>>> print s
[u'\u6211', u'\u662f', u'\u4e2d', u'\u56fd', u'\u4eba']
>>> print s[1]
是

# 第二种
>>> a = "我是中国人"
>>> s = a.decode('utf8')
>>> s = list(a.decode('utf8'))
>>> s
[u'\u6211', u'\u662f', u'\u4e2d', u'\u56fd', u'\u4eba']
>>> print s[1]
是
```
