Python os.mkdir, file exists

Question

I am trying to download videos, but when it goes to the next one, it returns the error saying that the folder already exists. There is no way to save more than one file?

def json_decoder(file):
    file = open(file, 'r')
    file = file.read().replace(chr(92) * 2, chr(92))
    file = codecs.decode(file, 'unicode_escape')
    lst = file.split('\n')
    tofile = []
    for i in lst:
        if not i:
            continue
        j = i.index(':') + 2
        k = i.index('"', 50)
        tofile.append(i[j:k])
    try:
        os.remove('output.txt')
    except OSError:
        pass
    with open('output.txt', 'w') as f:
        for item in tofile:
            print(item)
            f.write(f'{item}\n')

def get_files(data):
    file = open(data, 'r')
    lst = file.read().split('\n')
    for i in lst:
        if not i:
            continue
        video_name = i.split('=')[-1]
        print('Downloading ' + video_name)
        r = requests.get(i)
        if os.path.isdir("./" + video_name.split('-')[0]) is not True:
            os.mkdir(video_name[:3])
        with open(video_name[:3] + "/" + video_name, 'wb') as f:
            f.write(r.content)

I’m using python 3.7.1

Try to use the os.makedirs(), it has a parameter exist_ok that when True no error if directory already exists.

os.makedirs(video_name[:3], exist_ok=True)
