How to transform a string with a list of dicts within just to a list-CodePudding

I do have next string:

"[
    { 
     "name" : "name_1",
     "codes" : ["some_code_1", "some_code_2"]
     },
     
     {
     "name" : "name_2",
     "codes" : ["some_code_1", "some_code_2"] 
     }
  
]"

How can I make this string to be just a list type ?

CodePudding user response：

You could evaluate using the builtin eval wich i DO NOT RECOMMEND, or the "safe version" by ast wich is ast.literal_eval, but these two each have problems. The builtin eval() has security issues and the "safe" version is very rigorous in order to prevent malicious code.

I would suggest the JSON library, which provides a set of tools to encode and decode with json.

Just do this:

>> import json
>> to_decode = """
[
 { 
  "name" : "name_1",
  "codes" : ["some_code_1", "some_code_2"]
 },
 
 {
  "name" : "name_2",
  "codes" : ["some_code_1", "some_code_2"] 
 }
]"""
>>> #to decode it here is the solution...
>>> json.JSONDecoder().decode(to_decode)
[
{ 
 "name" : "name_1",
 "codes" : ["some_code_1", "some_code_2"]
 },
 
 {
 "name" : "name_2",
 "codes" : ["some_code_1", "some_code_2"] 
 }
]

Or you could use the loads() function instead:

>>> json.loads(to_decode)

Try using the json library:

import json

sampleString = """
[
    { 
        "name" : "name_1",
        "codes" : ["some_code_1", "some_code_2"]
    }, 

    {
        "name" : "name_2",
        "codes" : ["some_code_1", "some_code_2"] 
    }

]
"""

processedList = json.loads(sampleString)

print(processedList)
