Question

   <label for="CREDIT" class="_8J-bZE _3C6tOa _2i24Q8">
        <input type="radio" class="_2haq-9" name="paymentOptions" readonly="" id="CREDIT" value="on">
        <div class="_6ATDKp"></div>
         <div class="_2o59RR">
        </div>
        </label>

        <label for="NET_OPTIONS" class="_8J-bZE _3C6tOa _2i24Q8">
        <input type="radio" class="_2haq-9" name="paymentOptions" readonly="" id="NET_OPTIONS" value="on">
        <div class="_6ATDKp"></div>
        <div class="_2o59RR"></div>
        </label>

有两个具有相同类名的单选按钮，我想单击第二个（NET OPTIONS）。我是python和selenium的新手，任何帮助都会得到满足。我已经尝试过Xpath并找到ID但仍然没有成功

driver.find_element_by_id("NET_OPTIONS").click()
driver.find_element_by_xpath("//*[@id='container']/div/div[1]/div/div/div[1]/div[4]/div/div/div/div[3]/div/label[3]").click()

尝试上面的代码后，我收到此错误，但是单选按钮在页面上非常明显但是，webriver是能够找到它的:( .selenium.common.exceptions.ElementNotVisibleException：消息：元素不可见

Answer 1

试试这段代码，看看它是否有效 -

isBadSide = [1,1,1,0,0,0]

def R(s):
    if isBadSide[s-1]:
        return -s
    return s

def T(s, a, N):
    return [(1./N, s)]

def value_iteration(N, epsilon=0.001):
    "Solving an MDP by value iteration. [Fig. 17.4]"
    U1 = dict([(s, 0) for s in range(1, N+1)])
    while True:
        U = U1.copy()
        delta = 0
        for s in range(1, N+1):
            U1[s] = R(s) + max([sum([p * U[s1] for (p, s1) in T(s, a, N)])
                                        for a in ('s', 'g',)])

            delta = max(delta, abs(U1[s] - U[s]))

        if delta < epsilon:
             return U

    print(value_iteration(6))
    # {1: -1.1998456790123457, 2: -2.3996913580246915, 3: -3.599537037037037, 4: 4.799382716049383, 5: 5.999228395061729, 6: 7.199074074074074}

Answer 2

这非常简单。假设driver是您的Selenium webdriver，您只需通过它id找到它就可以点击您想要的按钮：

button = driver.find_element_by_id("NET_OPTIONS")
button.click()

需要帮助才能使用Selenium，PYTHON单击单选按钮
