python当中循环和异常的使用

python当中try....except和for循环结合

 try:
        sturl="0"
        for i in range(sumcy):
            j=str(i+1)
            print(j)
            urlPos=driver.find_element_by_xpath("id('_container_staff')/div[1]/div[1]/div["+j+"]/div[1]/span[1]").text#职位
            print(urlPos)
            strurl=driver.find_element_by_xpath("id('_container_staff')/div[1]/div[1]/div["+j+"]/div[1]/a[1]").text#姓名
            if urlPos==" ":
                break
            else:
                sturl="职位"+urlPos+"姓名"+strurl+sturl
        url[2]=sturl
        print(url[2])
    except:
        url[2]='0'
