这段代码存在一个问题，就是在导入requests模块时没有使用正确的语法。应该在每个导入模块的语句之间添加一个空格。请尝试修改import语句，如下所示：

import requests
import os
import time
import json
from tqdm import tqdm
import re

这样修改后，代码应该就可以正常运行了。如果还有其他问题，请告诉我。

相关问题

import requests, json import execjs class Baidufanyi(object): def init(self): self.url = 'https://fanyi.baidu.com/v2transapi?from=zh&to=en' self.headers = { "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/115.0.0.0 Safari/537.36", } def indetna(self, name, shuzi): data = { "query": name, "sign": shuzi } return data def jspojie(self): name = input(str('请输入需要翻译的文字：')) sign = name print(sign) return name, sign def dmet(self, datan): resqone = requests.post(url=self.url, data=datan, headers=self.headers) dict_data = json.loads(resqone.text)["trans_result"]["data"][0]['dst'] print(dict_data) def main(self): korr = self.jspojie() konaem=self.indetna(korr) self.dmet(konaem) if name == 'main': baidu = Baidufanyi() baidu.main()

根据您提供的代码，您在调用`indetna()`方法时缺少了一个必需的参数`shuzi`。您需要在调用`indetna()`方法时传递两个参数，一个是`name`，另一个是`shuzi`。修改您的代码如下：

def main(self):
    korr = self.jspojie()
    name, sign = self.jspojie()  # 获取name和sign
    konaem=self.indetna(name, sign)  # 传递name和sign给indetna方法
    self.dmet(konaem)

请注意，您还需要将`if name == 'main':`修改为`if __name__ == '__main__':`以确保在作为脚本直接运行时才执行`main()`方法。这样修改后的代码应该是这样的：

if __name__ == '__main__':
    baidu = Baidufanyi()
    baidu.main()

这样应该可以解决您遇到的错误。请记得检查其他部分的代码是否正确无误。

为这段代码import requests from bs4 import BeautifulSoup import pprint import json def download_all_htmls(): """下载所有列表页面的HTML，用于后续的分析""" htmls = [] headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36'} for idx in range(24): url = f"https://www.utusan.com.my/page/{idx+1}" print("craw html:", url) r = requests.get(url) if r.status_code != 200: raise Exception("error") htmls.append(r.text) return htmls htmls = download_all_htmls() print(htmls[0])，添加爬取的每页数据单存保存到txt中，txt命名为页面页码的代码，再添加每隔10s爬取20个页面的代码

添加取每页数据并保存到 txt 文件中的代码如下：

import requests
from bs4 import BeautifulSoup
import pprint
import json
import time

def download_all_htmls():
    """下载所有列表页面的HTML，用于后续的分析"""
    htmls = []
    headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36'}
    for idx in range(24):
        url = f"https://www.utusan.com.my/page/{idx+1}"
        print("craw html:", url)
        r = requests.get(url, headers=headers)
        if r.status_code != 200:
            raise Exception("error")
        htmls.append(r.text)
        with open(f"page{idx+1}.txt", "w", encoding="utf-8") as f:
            f.write(r.text)
    return htmls

htmls = download_all_htmls()
print(htmls[0])

在这个例子中，我们使用 `with` 语句打开一个命名为 `page{idx+1}.txt` 的文件，并将每页的 HTML 写入该文件中。

添加每隔 10 秒爬取 20 个页面的代码如下：

import requests
from bs4 import BeautifulSoup
import pprint
import json
import time

def download_all_htmls():
    """下载所有列表页面的HTML，用于后续的分析"""
    htmls = []
    headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36'}
    for idx in range(24):
        url = f"https://www.utusan.com.my/page/{idx+1}"
        print("craw html:", url)
        r = requests.get(url, headers=headers)
        if r.status_code != 200:
            raise Exception("error")
        htmls.append(r.text)
        with open(f"page{idx+1}.txt", "w", encoding="utf-8") as f:
            f.write(r.text)
        if (idx+1) % 20 == 0:
            print("Sleep for 10 seconds...")
            time.sleep(10)
    return htmls

htmls = download_all_htmls()
print(htmls[0])

在这个例子中，我们使用了 `time` 模块中的 `sleep()` 函数，使程序在每爬取 20 个页面后暂停 10 秒钟。这样可以降低爬虫的访问频率，减少被封禁的风险。
