我故意尝试找到错误的元素，以便可以调用 TimeoutException，然后再次调用该函数，但我看到了错误堆栈跟踪，但它不起作用。
代码:
def open_browser_func():
global driver
driver = webdriver.Chrome(service=ser)
wait = WebDriverWait(driver, 20)
driver.get("https://twitter.com/i/flow/login")
print("Opening login page")
try:
def sign_in_acc():
loginuser = wait.until(EC.visibility_of_element_located((By.NAME, "textt")))
loginuser.send_keys("Username", Keys.RETURN)
sign_in_acc_timer = threading.Timer(5, sign_in_acc)
sign_in_acc_timer.start()
except TimeoutException:
print("Username input crashed. Retrying now...")
def retry_sign_in():
driver.quit()
return open_browser_func()
retrytimer = threading.Timer(5, retry_sign_in)
retrytimer.start()
return driver
错误:

我看到的只是日志中的 TimeoutException，但不是我打算调用来处理它的内容。好像出了什么问题？
最佳答案
您正在等待不同线程中的元素。一旦您调用 sign_in_acc_timer.start()，您就会启动并行线程，其中正在执行等待，并且 open_browser_func() 完成。如果您想捕获子线程中的异常，可能值得阅读 Catch a thread's exception in the caller thread?
