I can not decode generated string to Python dict

I have a String, but I can't decode it to a dict using ast.literal_eval

FOUND THE ERROR, ENCODE THE STRING WRONG!

The string it should convert: (Link to the google Dock) https://docs.google.com/document/d/1jGjIPEzB9j48i1LDKQ2__Nhg5OE4R_jeaGCFq_DFr2M/edit?usp=sharing

Fallback:

Traceback (most recent call last):
  File "C:\Users\user\AppData\Local\Programs\Python\Python37-32\lib\tkinter\__init__.py", line 1705, in __call__
    return self.func(*args)
  File "C:/Users/user/Documents/Python/Documents/pickle_viewer/PickleViewer.py", line 444, in selectItem
    item_dict = ast.literal_eval(itemInfo["tags"][2])
  File "C:\Users\user\AppData\Local\Programs\Python\Python37-32\lib\ast.py", line 46, in literal_eval
    node_or_string = parse(node_or_string, mode='eval')
  File "C:\Users\user\AppData\Local\Programs\Python\Python37-32\lib\ast.py", line 35, in parse
    return compile(source, filename, mode, PyCF_ONLY_AST)
  File "<unknown>", line 1

Code to convert:

item_dict = ast.literal_eval(itemInfo["tags"][2])

This generates the string:

    def json_tree(tree, parent, dictionary):
                tmp_key = tree.insert(parent, 'end', uid, text=key + ' [...]', value="[...]", tag=(uid, True, dictionary[key]))

I think it's because of all the backslashes but I do not know where they're coming from

Can someone help me? Thanks.

Solution

Sorry, that was all my fault, I decoded the start string incorrectly. Now it is properly decoded and this saves me all the rest and I can easily use ast.literal_eval(STRING) again.

Nevertheless, many thanks for your answers.
