python脚本自动填调查问卷

参考地址：https://blog.csdn.net/qq_44864262/article/details/106838604?utm_medium=distribute.pc_relevant.none-task-blog-baidujs_baidulandingword-0&spm=1001.2101.3001.4242

准备

1、获得调查问卷的网址，我这里用的是腾讯问卷

2、下载谷歌浏览器

3、下载对应版本的chromedriver

ChromeDriver下载地址：http://chromedriver.storage.googleapis.com/index.html

浏览器打开问卷网页，按F12打开控制台，点击右侧窗口左上角的图标，点击左侧元素查看。

点击右侧的标签，右键复制元素的XPath，存下来备用，每个题的不同选项只有很小的差别，因此每个题随便选一个选项复制其XPath即可（依据个人情况）。

代码编写

思路：依据一定的概率生成问卷答案，用循环语句控制chormedriver对浏览器的各种操作，进而达到自动填写问卷的目的。这也可以用来做web测试和其他可以基于浏览器的自动化操作。

代码分析：

# 按给定的概率返回一个列表中的值
def number_of_certain_probability(sequence, probability):
    x = random.uniform(0, 1)
    cumulative_probability = 0.0
    for item, item_probability in zip(sequence, probability):
        # 只有当累加的概率比刚才随机生成的随机数大时候，才跳出，并输出此时对应的值
        cumulative_probability += item_probability
        if x < cumulative_probability:
            break
    return item

运行

执行write(n)调用函数，n为需要自动填写的次数。
