请问，老师

登陆页面通过press_keycode方式输入电话，但是有时候会重复输入，不知道为什么，例如我想输入15910312367，但是有时候数字会重复被输入，代码如和截图下图

def number_input():
    element = driver.find_element_by_id("com.kangfuzi.lefthanddoctor:id/phone_nums")
    elements = element.find_elements_by_class_name("android.widget.TextView")
    print(len(elements))
    print(elements)

    elements[0].click()
    driver.press_keycode(8)
    time.sleep(2)

    elements[1].click()
    driver.press_keycode(12)
    time.sleep(2)

    elements[2].click()
    driver.press_keycode(16)
    time.sleep(2)

    elements[3].click()
    driver.press_keycode(8)
    time.sleep(2)

    elements[4].click()
    driver.press_keycode(7)
    time.sleep(2)

    elements[5].click()
    driver.press_keycode(10)
    time.sleep(2)

    elements[6].click()
    driver.press_keycode(8)
    time.sleep(2)

    elements[7].click()
    driver.press_keycode(9)
    time.sleep(2)

    elements[8].click()
    driver.press_keycode(10)
    time.sleep(2)

    elements[9].click()
    driver.press_keycode(13)
    time.sleep(2)

    elements[10].click()
    driver.press_keycode(14)

实际想输入：

15910312367，

但是被输入了1151031223
