Question

我调试了代码，当程序到达这行代码（功能更大的代码）时......

login_result = login(driver)

...它会跳到下一行（没有错误或其他任何内容）

我试过运行它但输出的结果相同。

以下是login()功能：

def login(driver):

    # Check if logged in (or login failed)
    login_result = 1
    login_check_elements = driver.find_elements_by_tag_name('button')
    for login_check in login_check_elements:
        if(login_check.text == "Log in" and login_check.is_enabled()):
            # If there is a login button on the screen and the button is enabled by default it means
            # that the driver is on the account page and is not logged in
            login_result = 0

    # If login failed - return 1
    if(login_result == 1):
        return 1
    else:
        username, password = find_input_elements(driver)
        username.send_keys("username")
        time.sleep(randint(1, 3))
        password.send_keys("password")
        time.sleep(randint(1, 3))
        login_button = find_login_button(driver)
        login_button.click()
        return 0

*编辑：我忘了说，是的，我在函数的几乎每一行都包含了断点，包括第一行。

Answer 1

我的猜测是检查元素的行在其列表中没有任何内容。

for login_check in login_check_elements:

再次尝试运行代码，并检查login_result的值是什么

def login(driver):

# Check if logged in (or login failed)
login_result = 1
login_check_elements = driver.find_elements_by_tag_name('button')
for login_check in login_check_elements:
    print('element found')
    if(login_check.text == "Log in" and login_check.is_enabled()):
        # If there is a login button on the screen and the button is enabled by default it means
        # that the driver is on the account page and is not logged in
        login_result = 0

# If login failed - return 1
if(login_result == 1):
    return 1
else:
    username, password = find_input_elements(driver)
    username.send_keys("username")
    time.sleep(randint(1, 3))
    password.send_keys("password")
    time.sleep(randint(1, 3))
    login_button = find_login_button(driver)
    login_button.click()
    return 0

login_result = login(driver)
print(login_result)

最有可能的方法是将login_result设置为顶部的1，它永远不会找到元素，直接返回1

我的回答可能无法提供您正在寻找的解决方案，但我会抓住它。从函数login_result获取返回值后，您尚未说明执行了哪些检查。如果没有声明返回值，我猜这就是为什么你的代码只是继续执行。并且在函数中没有引发异常，它旨在返回并让用户对结果执行某些操作

def login(driver):

    # Check if logged in (or login failed)
    login_check_elements = driver.find_elements_by_tag_name('button')
    for login_check in login_check_elements:
        if login_check.text == "Log in" and login_check.is_enabled():
            # If there is a login button on the screen and the button is enabled by default it means
            # that the driver is on the account page and is not logged in
            return False
    else:
        username, password = find_input_elements(driver)
        username.send_keys("username")
        time.sleep(randint(1, 3))
        password.send_keys("password")
        time.sleep(randint(1, 3))
        login_button = find_login_button(driver)
        login_button.click()
        return True

login_result = login(driver)
if not login_result:
   # Error out or do something

函数只是在调用时跳过执行 - 尽管
