UnboundLocalError:赋值前引用的局部变量'name'

标签: python selenium selenium-webdriver

在我的条件下,我正在尝试为变量名称分配一个新值,但我收到的错误如下。

运行我的代码后,我得到了UnboundLocalError: local variable 'name' referenced before assignment

你有想法解决它吗?

如果变量是全局的

,我不知道为什么我会得到这个

我的代码

import pytest

fake = Faker("en_US")

    driver.find_element_by_css_selector(".btn.btn--primary").click()
    WebDriverWait(driver, 30).until(
        EC.visibility_of_element_located((By.XPATH, ".//*[@id='first-name']/input")))
    driver.find_element_by_xpath(".//*[@id='first-name']/input").send_keys(contributor_name)
    assert driver.find_element_by_css_selector(".actions-bar__nav-link.router-link-active").text == name
    time.sleep(3)

    duplicated_contributor_message = driver.find_element_by_css_selector(".field-error-text")

    if duplicated_contributor_message.is_displayed():

        name = fake.name() + fake.name()

        driver.find_element_by_xpath(".//*[@id='first-name']/input").clear()
        driver.find_element_by_xpath(".//*[@id='first-name']/input").send_keys(name)

def assert_created_contributor_is_found(driver):

    assert name in driver.find_element_by_css_selector(".search__results__list>li").text

def test_case_one(driver):

    login_to_cms(driver)
    access_contributor_page(driver)
    create_contributor_minimum_requirements(driver)
    search_created_contributor(driver)
    assert_created_contributor_is_found(driver)

功能有自己的范围。要访问全局变量,您需要明确说出:

 def create_contributor_minimum_requirements(driver):
     global name
     ...

希望它有所帮助!
