python - Scraper Python和YouTube API

Question

想要在某些 channel 统计数据中删除youtube，并了解其工作原理。并且比作csv作以下分析。使用this video创建和学习。

我有2个文件:
main.py，youtube_statistics

main.py

from youtube_statistics import YTstats

API_KEY = "xxx"
channel_id = "xxx"

yt = YTstats(API_KEY, channel_id)
yt.get_channel_statistics()

youtube_statistics.py

class YTstats:
    def_init_(self, api_key, channel_id)
    self.api_key = api_key
    self.channel_id = channel_id
    self.channel_statistics = None


def get_channel_statistics(self):
    url = f'https://www.googleapis.com/youtube/v3/channels?part=statistics&id={self.channel_id}&key={self.api_key}'
    print(url)

这不是全部代码，而是尝试运行主要的错误:

Traceback (most recent call last):
  File "D:/!Python/YouTube API/main.py", line 1, in <module>
    from youtube_statistics import YTstats
  File "D:\!Python\YouTube API\youtube_statistics.py", line 1, in <module>
    class YTstats:
  File "D:\!Python\YouTube API\youtube_statistics.py", line 2, in YTstats
    def_init_(self, api_key, channel_id)
NameError: name 'def_init_' is not defined

怎么了，怎么解决？在视频上一切正常。

谢谢。

在python中，缩进很重要。您的youtube_statistics.py文件缩进了错误的位置。特别是类初始化被声明为错误。这是固定版本:

class YTstats:
    def __init__(self, api_key, channel_id):
        self.api_key = api_key
        self.channel_id = channel_id
        self.channel_statistics = None


    def get_channel_statistics(self):
        url = f'https://www.googleapis.com/youtube/v3/channels?part=statistics&id={self.channel_id}&key={self.api_key}'
        print(url)
