未找到Python Selenium句柄InvalidArguementException文件

Question

我有一个脚本，可以使用send_键将文件加载到浏览器中，这很好，但是我想在找不到文件时处理一个异常，但无法找到执行此操作的方法，我尝试捕获InvalidArgumentException和IOError，但它们似乎都无法捕获异常

chooseFile = driver.find_element_by_class_name("GDTLPL2DNW");

try:
   chooseFile.send_keys("C:/temp/File.xml")

except IOError as e:
   print ("Unable to Locate xml file to import, please check source directory")
   exit( 
else:
    pass

我找到了更好的方法。在启动任何其他文件之前，只需使用os.path.isfile检查该文件是否存在
