--Install progress bar

It's good to know the progress

$ pip install tqdm

main.py

from tqdm import tqdm
from pytchat import Extractor, VideoInfo, SuperchatCalculator
import signal

'''
Progress bar showing progress
'''
class ProgressBar:
    def __init__(self,total):
        self.total = total*1000
        self.pbar = tqdm(total = self.total, ncols = 80, unit_scale = 1,
            bar_format='{desc}{percentage:3.1f}%|{bar}|'
                       '[{n_fmt:>7}/{total_fmt}]{elapsed}<{remaining}')
        
    def callback(self, actions, fetched):
        if self.total - fetched < 0:
            fetched = self.total
        self.total -= fetched
        self.pbar.update(fetched)
    
    def close(self):
        self.pbar.update(self.total)
        self.pbar.close()
    
    def cancel(self):
        self.pbar.close()

if __name__ == '__main__':
    video_id = "GY-LSsYVpJ4"
    info  = VideoInfo(video_id)
    print('Calculate Superchat: [title] ', info.get_title())    

    #Prepare a progress bar.
    pbar = ProgressBar(info.get_duration())
 
    #Extractor generation
    ex = Extractor(
        video_id,
        callback = pbar.callback,
        div = 10,
        processor = SuperchatCalculator()
    )

    #Ctrl+Cancel with C
    signal.signal(signal.SIGINT,  
        (lambda a, b: ex.cancel()))

    #Perform extraction
    result = ex.extract()

    #Display of aggregation results
    pbar.close()
    print(result)

in conclusion

All explanations can be found at the URL above. I was wondering if I could write an article just by introducing it. Also, it's hard to see json in super chat. I'll fix it. Please contact me if you have any questions. Thank you very much.
