Try this:

import ast

string = "['a', 'b', 'a e']['de']['a']['a']"
string = string.replace("]", "],")
list_ = list(ast.literal_eval(string))
print(list_)

output:

[['a', 'b', 'a e'], ['de'], ['a'], ['a']]

Keep in mind that this will fail if one of items in the list is a ] character.

Here is a simple way -

import ast

string = "['a', 'b', 'a e']['de']['a']['a']"

[ast.literal_eval(i+']') for i in string.split(']') if len(i)>0]

[['a', 'b', 'a e'], ['de'], ['a'], ['a']]
