Question

我试图从pickle文件夹中导入videoId，然后打印youtube视频的描述。我收到此错误='bytes'对象没有属性'findAll'，我想提取包含videoid和title的描述在csv中

cwd=os.getcwd()
parent_folder=os.path.join(cwd,'Data') pickle_out=open("C:/Users/india/Desktop/PARUL/Data/Pickle/vid_ids_dict.pickle","rb")
vid_id_dict=pickle.load(pickle_out)

dataset_folder=os.path.join(parent_folder,"Dataset")
if not os.path.exists(dataset_folder):
os.makedirs(dataset_folder)

csv_file_path= os.path.join(parent_folder,'main.csv')


base = "https://www.youtube.com/watch?v="
for keys, values in vid_id_dict.items():
for key in keys:
    query_dataset_folder=os.path.join(dataset_folder,key)

    if not os.path.exists(query_dataset_folder):
        os.makedirs(query_dataset_folder)

    for VidID in values:

        r = requests.get(base+VidID)
        soup = bs(r.text,'html.parser').encode("utf-8")
        name=VidID+".txt"
        save_description_link=os.path.join(query_dataset_folder,name)

        f= open(save_description_link,"a+")

        for title in soup.findAll('p', attrs={'id': 'eow-description'}):
            description=title.text.strip()
            f.write(description)
            print(description)
        f.close()

        for title in soup.findAll('span', attrs={'class': 'watch-title'}):
            vid_title= title.text.strip()
            print(vid_title)

        with open(csv_file_path, 'a+') as csvfile:
            fieldnames = ['Video id', 'Title','Description','Category']
            writer = csv.DictWriter(csvfile, fieldnames=fieldnames)
            writer.writerow({'Video id': VidID, 'Title': vid_title, 'Description':description,'Category':key})

错误- AttributeError Traceback（最近一次通话）在 35 f =打开（save_description_link，“ a +”） 36 ---> 37为soup.findAll（'p'，attrs = {'id'：'eow- 描述'}）： 38 description = title.text.strip（） 39 f.write（描述）

AttributeError：“字节”对象没有属性“ findAll”

我假设您正在使用 requests 模块来获取http响应。

只需将代码替换为：

r.encoding = 'utf-8'
soup = bs(req.content, 'html.parser')

最终运行代码：

for keys, values in vid_id_dict.items():
for key in keys:
    query_dataset_folder=os.path.join(dataset_folder,key)

    if not os.path.exists(query_dataset_folder):
        os.makedirs(query_dataset_folder)

    for VidID in values:

        r = requests.get(base+VidID)
        r.encoding = 'utf-8'
        soup = bs(r.content, 'html.parser')
        name=VidID+".txt"
        save_description_link=os.path.join(query_dataset_folder,name)

        f= open(save_description_link,"a+")

        for title in soup.findAll('p', attrs={'id': 'eow-description'}):
            description=title.text.strip()
            f.write(description)
            print(description)
        f.close()

        for title in soup.findAll('span', attrs={'class': 'watch-title'}):
            vid_title= title.text.strip()
            print(vid_title)

        with open(csv_file_path, 'a+') as csvfile:
            fieldnames = ['Video id', 'Title','Description','Category']
            writer = csv.DictWriter(csvfile, fieldnames=fieldnames)
            writer.writerow({'Video id': VidID, 'Title': vid_title, 'Description':description,'Category':key})
