Pytube : How to add the parameters for function progress_Check

Question

def progress_Check(stream = None, chunk = None, file_handle = None, remaining = None):
    global file_size
    #Gets the percentage of the file that has been downloaded.
    percent = (100*(file_size-remaining))/file_size
    print("{:00.0f}% downloaded".format(percent))

When calling the above function for returning download percentage from

yt = YouTube(link,on_progress_callback=progress_Check)

But I'm getting an error like can't subtract integer and None, So What are the function parameters/how to get them ?

Any Idea ??

Answer 1

progress_Check requires only 3 arguments: stream, chunk, and remaining

since only 3 arguments are needed, the 4th one isn't assigned to anything, therefore remaining would be set to None and would result in the error during the calculation

you also don't need to set each argument's default as None since those would get overriden anyways

here's the fixed code:

def progress_Check(stream, chunk, remaining):
    global file_size
    #Gets the percentage of the file that has been downloaded.
    percent = (100 * (file_size - remaining)) / file_size
    print("{:00.0f}% downloaded".format(percent))
