如何处理Python behave或BDD场景中的迭代/循环？

Scenario Outline: Login with different users
    Given I am on the login page
    When I enter "<username>" and "<password>"
    And I click on the login button
    Then I should be logged in

    Examples:
    | username | password |
    | user1    | pass1    |
    | user2    | pass2    |
    | user3    | pass3    |

from behave import *

@given('I am on the login page')
def step_given_i_am_on_the_login_page(context):
    # Code to navigate to the login page

@when('I enter "{username}" and "{password}"')
def step_when_i_enter_username_and_password(context, username, password):
    # Code to enter the username and password

@when('I click on the login button')
def step_when_i_click_on_the_login_button(context):
    # Code to click on the login button

@then('I should be logged in')
def step_then_i_should_be_logged_in(context):
    # Code to verify if the user is logged in

# This hook function will be executed before each scenario
@BeforeScenario
def before_scenario(context, scenario):
    # Code to perform iteration/looping logic
    pass
