str1 = " [[1,2,3],123,123.123,'abc',{'key1':(1,2,3),'key2':(4,5,6)}]"
str2 = [[1,2,3],123,123.123,'abc',{'key1':(1,2,3),'key2':(4,5,6)}]
需要使用json函数处理以上字符串。
其中，json函数只能处理str2，str1没法处理。
问题补充：
如果只是简单的是split函数的话，对于如下str就没法正确转换成对应list了

首先，str2不是个字符串。
str1这种情况可以通过2种方式来操作：
1. 使用json库
代码如下：
import json
str1 = " [[1,2,3],123,123.123,'abc',{'key1':(1,2,3),'key2':(4,5,6)}]"
str1_standard = str1.replace('(','[').replace(')',']').replace('\'','"')
str1_json = json.loads(str1_standard)
这么做是因为python在dump json中会把list输出为tuple，同时python支持'来标定字符串，所以需要将这种模式调整过来就行了。
可以参考这个链接：点我
2. 使用eval
代码如下：
str1 = " [[1,2,3],123,123.123,'abc',{'key1':(1,2,3),'key2':(4,5,6)}]"
str1_evaled = eval(str1)
同样也可以方便取得数据，不过这种方法对数据要求比较严格，在真实使用环境中最好加上try,except，免得直接抛出异常后停止运行。
eval相关的资料可以去google一下。
3. 补充问题
这个不能通过json格式化的原因是你的str中包含\"这种情况。
我将补充问题中的str简化一下，变为：
str = """["a","b","<a href=\"xxxx\">"]"""，这种形式其实是等效于
str = """["a","b","<a href="xxxx">"]"""
那么这个字符串中就会出现xxxx这一段什么都不属于，所以应该改成：
str = """["a","b","<a href=\\"xxxx\\">"]"""
再json.loads(str)就可以了。
一般而言，python下 可以使用 string 的 split 方法将字符串拆成列表，例如：
"a, b, c".split(',')
结果是
['a', ' b', ' c']
str3 = eval(str1)
print str3 == str2
