Selenium学习笔记||五、练习（天气网查最低温度）

from selenium import webdriver

driver = webdriver.Chrome(r"D:\webdriver\chromedriver_73.0.3683.68.exe")

driver.get("http://www.weather.com.cn/html/province/jiangsu.shtml")
eles = driver.find_element_by_id("forecastID")

citys = eles.text.split('℃\n')
lowest_temp = None
lowest_city = []

for city in citys:
    city_name = city.split('\n')[0]
    city_temp = city.split('\n')[1].replace("℃", "").split('/')
    city_low = int(city_temp[1])

    if lowest_temp == None or city_low < lowest_temp:
        lowest_temp = city_low
        lowest_city = [city_name]
    elif lowest_temp == city_low:
        lowest_city.append(city_name)

print("全省最低温度为：{}，出现在{}。".format(lowest_temp,'/'.join(lowest_city)))

driver.quit()

要求：

http://www.weather.com.cn/html/province/jiangsu.shtml获取江苏所有城市的天气，并找出其中每天最低气温最低的城市，显示出来，比如 温度最低为12℃, 城市有连云港 盐城
