Selenium Python - 如何引發異常並繼續循環？

Question

如果發現任何不匹配，我想拋出異常錯誤，但循環應該繼續。 如果有任何不匹配/異常錯誤，整個案例都應該失敗。 你們都可以檢查下面的代碼並在這里幫助我嗎？

 def test01_check_urls(self, test_setup):
        #reading the file
        Total_entries=len(old_urls)            //Total_entries=5
        print("Total entries in the sheet: "+ str(Total_entries))
        col_count=0

        #opening urls
        while col_count<Total_entries:
            Webpage=old_urls[col_count]          //fetching data from 1st cell in the excel
            Newpage=new_urls[col_count]          //fetching data from 1st cell in the excel
            driver.get(Webpage)
            print("The old page url is: "+Webpage)
            page_title=driver.title
            print(page_title)
            Redr_page=driver.current_url
            print("The new url is: "+Redr_page)
            print("New_url from sheet:"+Newpage)

            try:
                if Redr_page==Newpage:
                    print("Correct url")
            except:
                raise Exception("Url mismatch")

            col_count+=1

有一個變量url_mismatch ，最初是False 。 當 URL 不匹配時，不要立即引發異常，只需將此變量設置為True 。 然后當循環結束時，檢查該變量的值，如果該變量為True則引發異常。

但是，尚不清楚您的try塊如何導致異常。 您可能是說（不需要try塊）：

if Redr_page == Newpage:
    print("Correct url")
else:
    raise Exception("Url mismatch")

現在我不修改那部分代碼：

url_mismatch = False
while col_count<Total_entries:
    Webpage=old_urls[col_count]          //fetching data from 1st cell in the excel
    Newpage=new_urls[col_count]          //fetching data from 1st cell in the excel
    driver.get(Webpage)
    print("The old page url is: "+Webpage)
    page_title=driver.title
    print(page_title)
    Redr_page=driver.current_url
    print("The new url is: "+Redr_page)
    print("New_url from sheet:"+Newpage)

    try:
        if Redr_page==Newpage:
            print("Correct url")
    except:
        print('Mismatch url')
        url_mismatch = True # show we have had a mismtach

    col_count+=1
# now check for a mismatch and raise an exception if there has been one:
if url_mismatch:
    raise Exception("Url mismatch")
