如果 selenium 無法找到元素，我如何使關閉 selenium 無效

Question

如果元素存在，我試圖返回 false，但如果元素不存在，我不想結束程序。
我的問題是，當 Selenium 找不到元素時，它會關閉所有但我不想關閉它，我想運行代碼的 rest。
可能嗎？

我的 Python 代碼：

if driver.find_element_by_xpath("//a[@class='btn btn-primary im_edit_forward_btn disabled']") != 0 :     
    print("Break here")
    return False

print("Running the rest")
encaminhar = driver.find_element_by_xpath("//a[@class='btn btn-primary im_edit_forward_btn']")
encaminhar.click()

Output：

Traceback (most recent call last):
  File "webscraping.py", line 94, in <module>
    if forwardMessages():
  File "webscraping.py", line 57, in forwardMessages
    if driver.find_element_by_xpath("//a[@class='btn btn-primary im_edit_forward_btn disabled']") != 0 :

您可以捕獲異常。

from selenium.common.exception import NoSuchElementException

try:
    driver.find_element_by_xpath("//a[@class='btn btn-primary im_edit_forward_btn disabled']")
except NoSuchElementException:
    pass
