Python split函数处理str转list的问题,pythonsplit,str1 = " [[1


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

str3 = eval(str1)print str3 == str2

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 jsonstr1 = " [[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

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']
