Your choice of method with urllib is.. very inefficient.

as the title states, your use of urllib leaves a lot to be desired both speed and logic wise.

Here's a refactored version of your download() function which is not only MUCH faster, but also only uses the requests library for bolstered optimization and simplicity.

def download(url: str, fileName: str):
    response = requests.get(url, stream=True)
    response.raise_for_status()
    length = response.headers.get('content-length')
    block_size = 1000000  # default value
    if length:
        length = int(length)
        block_size = max(4096, length // 20)
    with open(fileName, 'wb') as f:
        size = 0
        for buffer in response.iter_content(block_size):
            if not buffer:
                break
            f.write(buffer)
            size += len(buffer)
            if length:
                percent = int((size / length) * 100)
                print(f"Downloading {fileName}: {percent}%", end='\r')
    print(f"\nDone Downloading: {fileName}")
