Python 百度搜索爬虫工具：完整代码及使用教程

以下是经过修改的完整代码：

import requests
from bs4 import BeautifulSoup
import time
import tkinter as tk
import webbrowser

def crawl_baidu(keyword):
    headers = {
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36'
    }
    url = f'https://www.baidu.com/s?wd={keyword}'
    time.sleep(0.5)  # 添加延迟
    response = requests.get(url, headers=headers)
    soup = BeautifulSoup(response.text, 'html.parser')

    results = []
    for result in soup.find_all('div', class_='result'):
        result_url = result.find('a')['href']
        results.append(result_url)

    return results

def open_url(event):
    index = result_text.index(tk.CURRENT)
    tag_ranges = result_text.tag_ranges('link')
    for tag_range in tag_ranges:
        if int(result_text.index(tk.CURRENT).split('.')[0]) in range(int(str(tag_range[0]).split('.')[0]), int(str(tag_range[1]).split('.')[0])):
            url = result_text.get(tag_range[0], tag_range[1])
            if url:
                webbrowser.open(url)
            break

def search():
    keyword = entry.get()
    search_results = crawl_baidu(keyword)
    if len(search_results) > 0:
        for index, url in enumerate(search_results, start=1):
            result_text.insert(tk.END, f'{index}. {url}
', 'link')
            result_text.tag_configure('link', foreground='blue', underline=True)
            result_text.tag_add('link', f'{index}.0', f'{index}.end')
        result_text.insert(tk.END, '
')
    else:
        result_text.insert(tk.END, '没有搜索结果
')

# 创建UI界面
window = tk.Tk()
window.title('百度搜索')
window.geometry('800x600')

label = tk.Label(window, text='请输入关键词:')
label.pack()

entry = tk.Entry(window)
entry.pack()

search_button = tk.Button(window, text='搜索', command=search)
search_button.pack()

result_text = tk.Text(window)
result_text.pack()

result_text.bind('<Button-1>', open_url)

window.mainloop()

在这个修改后的代码中，我使用了str.split函数将索引转换为整数进行比较，以避免了之前的TypeError错误。希望这次能够成功运行。如果还有其他问题，请随时提问。
