python - Python：RecursionError：调用 Python 对象时超出最大递归深度

问题描述

我一直在构建的代码今天遇到了这个错误，我无法弄清楚什么是错误的以及它发生的原因。

错误：

这将获得最后一条未读消息。

def w:
    try:
        post = driver.find_elements_by_class_name("_12pGw")
        ultimo = len(post) - 1
        texto = post[ultimo].find_element_by_css_selector(
            "span.selectable-text").text
        return texto
    except Exception:
        loop()

这会从 pandas df 创建一个字典，并用匹配的答案回复用户。

def y:
    df = pd.read_excel(r'D:\Drive\Outros\Python\Project\Dict.xlsx', error_bad_lines=False, encoding='utf-8-sig')
    d = df.set_index('msg')['reply'].to_dict()
    try:
        input_field = driver.find_element_by_class_name("_3u328")
        try:
            x = next(v for k, v in d.items() if last_msg() in k)
        except StopIteration:
            x = 'Não entendi, este comando é invalido'
        input_field.send_keys(x)
        time.sleep(1)
        driver.find_element_by_class_name("_3M-N-").click()
        try:
            driver.find_element_by_class_name("_2zCfw").send_keys('Lonely bot')
            driver.find_element_by_xpath("//span[@title = '{}']".format('Lonely bot')).click()
            driver.find_element_by_class_name("_2heX1").click()
            WebDriverWait(driver, 600).until(EC.invisibility_of_element_located((By.NAME, "status-time")))
        except TimeoutException:
            loop()
    except NoSuchElementException:
        loop()

这里我定义了一个循环来保持代码在线

def loop:
    try:
        z()
        time.sleep(1)
        w()
        y()
        driver.refresh()
    except TimeoutException:
        loop()

这是第一次阅读和回复。

while True:
    try:
        open_chatroom()
        time.sleep(1)
        w()
        y()
        driver.refresh()
    except TimeoutException:
        loop()

我以前从未经历过这种情况。我怎样才能更改我的代码，以便我的循环不会因此错误而中断？
