Что означает и к чему это?

Question

[DanTheMan]

Возникла ошибка при запуске кода. Я пробую запустить код из терминала, но там пишет ошибка

NameError: name 'flow' is not defined

К чему это?
Вот код

from oauth2client.client import OAuth2WebServerFlow
from oauth2client import tools
from oauth2client.file import Storage

CLIENT_ID = '<21321833276-1dcqm3th5f77f6v82casfl2nm9vdbqcl.apps.googleusercontent.com>'
CLIENT_SECRET = '<INe-Bl4RRauAlZvEwteXxNSM>'

flags = tools.argparser.parse_args(args=[])
creds = tools.run_flow(flow, storage, flags=None, http=None)

tools.run_flow()

К тому что у тебя не определенна переменная flow которую ты передаешь как атрибут в строке
creds = tools.run_flow(flow, storage, flags=None, http=None)

Смотри у меня есть модуль oauth2client.tools и там хранятся данные смотри, вот

def run_flow(flow, storage, flags=None, http=None):
    """Core code for a command-line application.

    The ``run()`` function is called from your application and runs
    through all the steps to obtain credentials. It takes a ``Flow``
    argument and attempts to open an authorization server page in the
    user's default web browser. The server asks the user to grant your
    application access to the user's data. If the user grants access,
    the ``run()`` function returns new credentials. The new credentials
    are also stored in the ``storage`` argument, which updates the file
    associated with the ``Storage`` object.

    It presumes it is run from a command-line application and supports the
    following flags:

        ``--auth_host_name`` (string, default: ``localhost``)
           Host name to use when running a local web server to handle
           redirects during OAuth authorization.

        ``--auth_host_port`` (integer, default: ``[8080, 8090]``)
           Port to use when running a local web server to handle redirects
           during OAuth authorization. Repeat this option to specify a list
           of values.

        ``--[no]auth_local_webserver`` (boolean, default: ``True``)
           Run a local web server to handle redirects during OAuth
           authorization.

    The tools module defines an ``ArgumentParser`` the already contains the
    flag definitions that ``run()`` requires. You can pass that
    ``ArgumentParser`` to your ``ArgumentParser`` constructor::

        parser = argparse.ArgumentParser(
            description=__doc__,
            formatter_class=argparse.RawDescriptionHelpFormatter,
            parents=[tools.argparser])
        flags = parser.parse_args(argv)

    Args:
        flow: Flow, an OAuth 2.0 Flow to step through.
        storage: Storage, a ``Storage`` to store the credential in.
        flags: ``argparse.Namespace``, (Optional) The command-line flags. This
               is the object returned from calling ``parse_args()`` on
               ``argparse.ArgumentParser`` as described above. Defaults
               to ``argparser.parse_args()``.
        http: An instance of ``httplib2.Http.request`` or something that
              acts like it.

    Returns:
        Credentials, the obtained credential.

Откуда программе знать, чему равна ваша flow

[DanTheMan]

Видишь там параметры функции и вызов присваивается мое переменной сначало

[javedimka]

DanTheMan: Это просто функция которой ты должен передать СВОИ значения, не определяется в ней flow. Попробуй вместо flow написать OAuth2WebServerFlow

Answer 1

[Ильяс]

в этой строке используется переменная flow, она нигде не определена

creds = tools.run_flow(flow, storage, flags=None, http=None)
