I use Python2.7. You need to convert str-> dict and the ast.literal_eval command does a good job, but only in the terminal:

$python >>>import ast >>>s = '{...}' #str type >>>d = ast.literal_eval(s) #dict type

When I add this script to the program, magic happens and it stops working. It looks like this:

 result = re.recognize_by_file(inputFile, X) result_dict = ast.literal_eval(result)

Here when you add this code - the error takes off:

 File "<string>", line 0 ^ SyntaxError: unexpected EOF while parsing

I read that the problem may be in the Python version, but there is no possibility to change it. Type inference and an example of the result string itself:

 print(result)

{"status": {"msg": "No result", "code": 1001, "version": "1.0"}}

 print(type(result))

type 'str'

 result_dict = ast.literal_eval(result) #Ну дальше типы я не могу выводить, потому что вылетает ошибка.

The full output looks like this:

    Here you need to use json.loads - andreymal

In Python, source code padding has the meaning:

 >>> import ast >>> ast.literal_eval('""\n') '' >>> ast.literal_eval('""\n ') Traceback (most recent call last): ... return compile(source, filename, mode, PyCF_ONLY_AST) File "<unknown>", line 2 ^ SyntaxError: unexpected EOF while parsing

On the last line there is an unexpected indent. The error is an artifact of the implementation of ast.literal_eval() (a possible bug, since for recognition of constants, spaces at the end should not have a value — the result is one value, not a set of instructions). You can bypass this behavior with .rstrip() .

In your case, it's better to json.loads() as @andreymal recommended .
