I installed python and run the command in terminal and I got this:

Calling url https://todoist.com/API/login?password=%5B234234246645%5D&email=%5Bmyemailaddress%40gmail.com%5D
Traceback (most recent call last):
  File "import.py", line 62, in <module>
    todoist_api = TodoistAPI(args.todoist_email, args.todoist_password)
  File "import.py", line 16, in __init__
    self.token = self._api_call('login', {'email': email, 'password': password}, add_token=False)['token']
  File "import.py", line 28, in _api_call
    raise Exception('Call finished with error! %s' % return_value)
Exception: Call finished with error! LOGIN_ERROR

The login info is correct I typed it as you advised:
python import.py [wunderlist_dump.json] [wrote my email here] [wrote my password here]

Is it required to type the email and password somewhere inside .py file as well? Please advice what am I doing wrong?
