Here are the steps to include a progress bar in pytube:

1. Install the tqdm package using pip: pip install tqdm
2. Import tqdm module: from tqdm import tqdm
3. Create a function to handle progress updates:

def progress_bar(stream, chunk, bytes_remaining):
    size = stream.filesize
    progress = (size - bytes_remaining) / size
    bar_length = 40
    progress_bar = "[" + "=" * int(progress * bar_length) + \
                   " " * (bar_length - int(progress * bar_length)) + \
                   "]"
    percent = int(progress * 100)
    tqdm.write(f"Downloading: {progress_bar} {percent}%")

This function takes in the stream, chunk, and bytes remaining as parameters. It calculates the progress and percentage and displays them in a progress bar using the tqdm module.

1. Update the download method:

video = YouTube(url, on_progress_callback=progress_bar)

Add a parameter on_progress_callback to the YouTube object and pass in the progress_bar function.

Now, when you download a video, you will see a progress bar showing the download progress.
