Python内部和外部for循环

Question

我首先希望代码执行第一个循环。完成后，我希望代码执行内部循环，它确实如此。但是当没有选项运行内循环时，我希望代码回到外循环，但它不会这样做。

有谁知道我如何做到这一点？

    def loop_function():

    #Search client
    searchCustomerButton = driver.find_element_by_xpath('//*[@id="ibSearchPatient"]')
    searchCustomerButton.click()    

    followLoop = range(0, 10)
    for x in followLoop:
        xpath = '//*[@id="ctl00_CPH_Main_ctl00_RadGrid_Patienten_ctl00__'
        xpath += str(x)
        xpath += '"]/td[3]'
        
        #Click on cliënt ID
        driver.find_element_by_xpath(xpath).click()

        #Click on Zorgtraject
        zorgtrajectButton = driver.find_element_by_xpath('//*[@id="ctl00_CPH_Top_ToolBar_MenuCurrentPage"]/div/ul/li[3]/a/span/span/span')
        zorgtrajectButton.click()

        followLoop2 = range(0,10)
        for x in followLoop2:
        # begin the inner loop with:
            try:
                # inner loop code here
                xpath2 = '//*[@id="ctl00_CPH_Main_ctl00_RadGrid1_ctl00__'
                xpath2 += str(x)
                xpath2 += '"]/td[2]'

                #Click on Zorgtraject ID
                driver.find_element_by_xpath(xpath2).click()

                dossierButton.click()

                #Dropdown select

                dropdownSelector.click()

                #Prevent not interactable error
                time.sleep(2)

                #Select 50
                selectDropdown = driver.find_element_by_xpath('//*[@id="ctl00_CPH_Main_ctl00_Verslagen_radGridBehandelVerloop_ctl00_ctl03_ctl01_PageSizeComboBox_DropDown"]/div/ul/li[4]')
                selectDropdown.click()

                #Check all documents
                tickDossier = driver.find_element_by_xpath('//*[@id="ctl00_CPH_Main_ctl00_Verslagen_radGridBehandelVerloop_ctl00_ctl02_ctl01_headerChkboxPrint"]')

                printButton = driver.find_element_by_xpath('//*[@id="ctl00_CPH_Main_ctl00_Verslagen_btnPrintBehandelverloop"]')
                printButton.click()

                #Click on Zorgtraject ID
                zorgtrajectButton2 = driver.find_element_by_xpath('//*[@id="ctl00_CPH_Top_ToolBar_MenuCurrentPage"]/div/ul/li[3]/a/span/span/span')
                zorgtrajectButton2.click()

            except NoSuchElementException: # define here what type of exception is thrown when there is no option to run the inner loop
                loop_function()  # call the function once again if you want to run the outer loop again
            
exec(loop_function())

您可以将整个代码包装成这样的函数：

def loop_function():
    followLoop = range(0, 10)
    for x in followLoop:
       # outer loop code here
        for x in followLoop2:
           # begin the inner loop with:
           try:
              # inner loop code here
           except NoSuchElementException: # define here what type of exception is thrown when there is no option to run the inner loop
              loop_function()  # call the function once again if you want to run the outer loop again
