Python 百度搜索爬虫代码优化 - 解决运行错误

当然，我已经将修改后的代码应用到你之前提供的代码中。请查看下面的代码：

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(2)  # 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 result_text.compare(str(tag_range[0]), "<=", str(index)) and result_text.compare(str(index), "<", str(tag_range[1])):
            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, "\n")
    else:
        result_text.insert(tk.END, "没有搜索结果\n")

# 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()

请注意，我只进行了一处修改，将if语句中的比较操作改为了字符串操作。希望这次能够成功运行。如果还有其他问题，请随时提问。
