尝试使用elif：

import random
Olist = []

while True:
    counter = 0
    counter2 = 0
    print("\nWelcome to exercise 05")
    InH1 = str(input("\nDo you wish to continue? (y/n):"))

    if InH1 == 'y':
        list1 = random.sample(range(30),11)
        list2 = random.sample(range(30),9)
        print("\n<><>Two random lists have been generated.<><>")
        print(list1)
        print(list2)
        max_index = len(list2)-1
        print("\n<><>Max index has been generated.<><>")
        print(max_index)
        InD = str(input("\nStart the func? (y/n):"))
        if InD == 'n':
            break
        if InD == 'y':
            print(list1[counter2])
            print(list2[counter])
            while counter < max_index:
                if counter2 == 11:
                    print(Olist)
                    InL = str(input("\nEnter any key to return to the start of the program,\
                                  or,\n enter 'q' to break the program."))
                    if InL == 'q':
                        break

                if list1[counter2] == list2[counter]:
                    Olist.append(list2[counter])
                    counter += 1
                else:
                    counter += 1

    if InH1 == 'n':
        break

或Actions：

WebElement element = driver.findElement(By.xpath("//div[@class='b-checkbox']//label//input[@type='checkbox']"));
Actions action = new Actions(driver);
action.moveToElement(element).click(element).build().perform();
