浅谈Python traceback的优雅处理

刚接触Python的时候，简单的异常处理已经可以帮助我们解决大多数问题，但是随着逐渐地深入，我们会发现有很多情况下简单的异常处理已经无法解决问题了，如下代码，单纯的打印异常所能提供的信息会非常有限。 def func1(): raise Exception("--func1 exception--") def main(): try: func1() except Exception as e: print e if __name__ == '__main__': main() 执行后输出如下： –func1 exception– 通过示例，我们发现

这是一个 Selenium 的异常信息，提示找不到指定的元素，可能是因为网页加载速度过慢或者元素定位表达式有误。你可以检查一下定位表达式是否正确，或者加入适当的等待时间来确保元素已经加载完成。另外，你也可以通过打印当前页面的 HTML 代码来查看元素是否存在，可以使用 driver.page_source 来获取当前页面的 HTML 代码。
