XPath increment with Python

Question

I'm trying to increment the variable 'xpath', but it does not work with the code underneath. Does anyone know how I can fix this? If I don't use the function, the inner loop does not work, so I need to keep that part that way (as far as I know).

Any help would be much appreciated! Thanks in advance!

#Function to export data
def loop_function():

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

    #Loop client ID's
    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()

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

Have you tried using f-string?

xpath = f'//*[@id="ctl00_CPH_Main_ctl00_RadGrid_Patienten_ctl00__{x}"]/td[3]'

But, if this pattern is always true, I would prefer using starts-with to find all elements at once, and then loop.

xpath = '//*[starts-with(@id, "ctl00_CPH_Main_ctl00_RadGrid_Patienten_ctl00__")]'

I guess you could accomplish what you want looping through elements and breaking the second loop when NoSuchElementException:

# Function to export data
def loop_function():
    # Search client
    searchCustomerButton = driver.find_element_by_xpath('//*[@id="ibSearchPatient"]')
    searchCustomerButton.click()

    # Loop client ID's
    followLoop = range(0, 10)
    for x in followLoop:
        xpath = f'//*[@id="ctl00_CPH_Main_ctl00_RadGrid_Patienten_ctl00__{x}"]/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()

        # Loop Zorgtraject ID's
        followLoop2 = range(0, 10)
        for x in followLoop2:
            try:
                xpath2 = f'//*[@id="ctl00_CPH_Main_ctl00_RadGrid1_ctl00__{x}"]/td[2]'

                # Click on Zorgtraject ID
