Using Python and WebDriver to automatically fill in the province and city drop-down boxes on web pages

Use Python and WebDriver to automatically fill in the province and city drop-down boxes on web pages

Introduction:
In web forms, we often encounter province and city selection drop-down boxes, and between these drop-down boxes There is a certain dependency relationship. Filling in these drop-down boxes manually is a tedious and time-consuming task, but by using Python and WebDriver, we can automatically fill in these drop-down boxes and improve work efficiency. This article will introduce how to use Python and WebDriver to automatically fill in the province and city drop-down boxes on web pages, and provide code examples.

Step 1: Install the necessary software and libraries
First, we need to install the following software and libraries: Python, Chrome browser and corresponding WebDriver, Selenium libraries. Once the installation is complete, we can start writing Python code.

Step 2: Import the necessary libraries and modules
In the Python code, we need to import the WebDriver module of the Selenium library and the drop-down box selection support module Select, as well as the time module.

from selenium import webdriver
from selenium.webdriver.support.ui import Select
import time

Step 3: Create a browser object and open the specified web page

driver = webdriver.Chrome() # 创建Chrome浏览器对象
driver.get("https://example.com") # 打开指定网页，替换为你要填写的网页链接

Step 4: Locate the drop-down box elements of provinces and cities
Use the find_element method of WebDriver to locate the provinces and cities Drop down box element.

province_select = Select(driver.find_element_by_id("province")) # 定位省下拉框元素
city_select = Select(driver.find_element_by_id("city")) # 定位市下拉框元素
district_select = Select(driver.find_element_by_id("district")) # 定位区下拉框元素

Step 5: Select the corresponding province, city, or district
Use the select_by_value or select_by_visible_text method of Select to select the value in the drop-down box.

province_select.select_by_value("北京市") # 选择省
time.sleep(2) # 等待一段时间，确保下拉框数据加载完成
city_select.select_by_value("市辖区") # 选择市
time.sleep(2)
district_select.select_by_value("东城区") # 选择区

Step 6: Submit the form
After selecting the province and city, you can submit the form by clicking the submit button or other interactive methods.

submit_button = driver.find_element_by_id("submit-button") # 定位提交按钮
submit_button.click() # 点击提交按钮

Step 7: Close the browser object
Finally, we need to close the browser object and release resources.

driver.quit() # 关闭浏览器对象

Summary:
By using Python and WebDriver, we can automatically fill in the province and city drop-down boxes in the web page. First, we need to install the necessary software and libraries; second, we import the necessary libraries and modules; then, we create a browser object and open the specified web page; next, we locate the province and city drop-down box element and select the corresponding value ;Finally, we submit the form and close the browser object. The above are the steps for automatically filling in the province and city drop-down boxes, and the corresponding code examples are attached. I hope this article can help you improve your work efficiency.
