I wrote code like this. But I don't know why need to attach the channels behind "?"?Is it because the channels receives various parameters?I wrote the code without "?" and then got a result of "cannot found page".And then attach "?" got a result
"""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)"""
outputcannot found page
expectedwhat is function of "?"
