我的代码有什么问题。 在Excel中，我有n个值（行），因为只有第一个值代码才能成功执行。其余的值都会增加，但
xpath = "//input[@value='Analyze' and contains(@onclick,'" + st_string + "')]"
#cont = 0
if driver.find_elements_by_xpath(xpath):
这段代码之后，控件将Excel移回for（循环），并在一段时间后引发ValueError。
except Exception:
if st == str(st):
xpath = "//input[@value='Analyze' and contains(@onclick,'" + st + "')]"
#cont1=0
这里抛出一个异常

任何人都可以帮助我，谢谢。
