Hope this will work for you

names = os.listdir()

for name in names:
   if('_RV.txt' in name):
      b.append(name)

for i in range(len(b)):
    print(str(i) + '  ' + b[i])

choice = int(input('Enter Choice : '))
name = b[choice]

#name = 'kono-koi-wa-tsumi-na-no-ka'
#name = input("Enter FileName : ")
quality = int(input("Enter Quality 
(0=480p,1=720p,2=1080p)"))
quality_t = '-480.mp4'
if quality == 1:
    quality_t = '-720.mp4'
elif quality == 2:
    quality_t = '-1080.mp4'
#def start():
file = open(name,'r')
a= file.read()
list2 = list(a.split('\n'))
file.close()

list_3 = []

for url in list2:
   res = requests.get(url)
   if (str(res)!='<Response [404]>'):

       download')

    print(f"Downloading 
    {elem1[0].text}")


    if len(elem)==0:

    for i in range(len(elem)):
        try:
            if quality_t in elem[i].get('href'):

                break
        except :
