在程序中，以下代码存在错误：

city = soup.find_all('ul class_="weaul"', class_='crumbs fl').find_all('a')[-1].text.strip()

weather = soup.find_all('ul class_="weaul"', class_='wea').text.strip()

temperature = soup.fin_alld('ul class_="weaul"', class_='tem').span.text.strip()

wind = soup.find_all('ul class_="weaul"', class_='').i.text.strip()

humidity = soup.find_all('ul class_="weaul"', class_='humidity').span.text.strip()

应将上述代码修改为：

city = soup.find('div', class_='crumbs fl').find_all('a')[-1].text.strip()

weather = soup.find('ul', class_='weaul').find('p', class_='wea').text.strip()

temperature = soup.find('ul', class_='weaul').find('p', class_='tem').span.text.strip()

wind = soup.find('ul', class_='weaul').find('p', class_='win').i.text.strip()

humidity = soup.find('ul', class_='weaul').find('p', class_='hum').span.text.strip()

修改后的代码如下：

import requests
from bs4 import BeautifulSoup

# 构造请求url
url = 'https://www.tianqi.com/zhongmou/10/'

# 发送GET请求
headers={'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/114.0.0.0 Safari/537.36 Edg/114.0.1823.43'}
response = requests.get(url,headers=headers)

# 判断请求是否成功
if response.status_code == 200:
    # 解析HTML页面
    soup = BeautifulSoup(response.text, 'html.parser')
    # 获取天气信息
    city = soup.find('div', class_='crumbs fl').find_all('a')[-1].text.strip()
    weather = soup.find('ul', class_='weaul').find('p', class_='wea').text.strip()
    temperature = soup.find('ul', class_='weaul').find('p', class_='tem').span.text.strip()
    wind = soup.find('ul', class_='weaul').find('p', class_='win').i.text.strip()
    humidity = soup.find('ul', class_='weaul').find('p', class_='hum').span.text.strip()
    # 将天气信息写入文本文件
    with open('weather.txt', 'w', encoding='utf-8') as f:
        f.write(f"城市：{city}\n天气：{weather}\n温度：{temperature}\n风力：{wind}\n湿度：{humidity}")
else:
    print("请求天气预报数据失败！")

这样就可以正确的获取天气信息并将其写入文本文件中了。
