真服气，一直这句话

chmod: chmod '269953fb.0' to 100777: Read-only file system

老师，结果为什么是方法不被允许啊。我访问你们提供的网址进行提交是这样，我对我自己的网站进行提交也是这样

老师这里为啥说这个百度访问天气这里的爬虫的url必须有百度的必须的参数???????

不加这个就说网络不行,是反爬机制吗????????

老师我这个小说内容没有换行，应该怎么换行呢

老师，为啥我这里不显示item呢，就只有两项

跟视频一摸一样，就给我报错，nb

import requests
from fake_useragent import UserAgent
from pyquery import PyQuery as pq

def test_pyquery():
    url = 'https://www.maoyan.com/films?showType=3'

    headers = {'User-Agent': UserAgent().chrome}
    resp = requests.get(url, headers=headers)

    doc = pq(resp.text)
    name_divs = doc('div.channel-detail.movie-item-title')
    names = [name_divs.eq(i).text() for i in range(len(name_divs))]
    score_divs = doc('div.channel-detail.channel-detail-orange')
    scores = [name_divs.eq(i).text() for i in range(len(score_divs))]

    for name,score in zip(names,scores):
        print(f'名称:{name}  评分:{score}')

if __name__ == '__main__':
    test_pyquery()

为什么会进入测试，而不是直接打印结果

import requests

from fake_useragent import UserAgent

def test_get():

    url = 'http://www.baidu.com/s'

    headers = {'User-Agent'}

    # 构建传递的参数

    params = {'wd':'python爬虫'}

    # 发送请求

    resp = requests.get(url,headers=headers,params=params)

    # 打印结果

    print(resp.text[:])

def test_post():

    url = 'https://www.kuaidaili.com/login/'

    headers = {'User-Agent':UserAgent().chrome}

    # 构建传递的参数

    data = {

    'username': '1234567890-',

    'passwd': '1234567890',

    'login_type': '1',

    'next': '/'

   }

    # 发送请求

    resp = requests.post(url,headers=headers,data=data)

    # 打印结果

    print(resp.text[:])

if __name__ == 'main':

    #test_get()

    test_post()

我这个为啥打印不出来东西

老师，请问我调试程序的时候 debugger之后出现：

想请问这是怎么回事呀

然后想要重新执行程序的时候，出现下面的内容？想请问这是怎么回事呀？要怎么解决？

老师，滑动类似我们百战滑到最右边的这种滑块不成功可能的问题出在哪里

老师这个一打开就这样，不知道怎么弄

老师，我这个为什么生成器生成不了

终端代码是这个
