Why isn't the first song of the .txt list being read?-CodePudding

My .txt file first song is Knife Party - Internet Friends and second song is Galantis - Louder, Harder, Better. But my code only outputs the second song. Why is that?

##5.4 Jukebox
failinimi = input("Sisesta failinimi: ")
 
if failinimi == "jukebox.txt":
    failinimi = "ut/jukebox.txt"
elif failinimi == "80ndad.txt":
    failinimi = "ut/80ndad.txt"
elif failinimi == "eesti_muusika.txt":
    failinimi = "ut/eesti_muusika.txt"
else:
    failinimi = "ut/edm.txt"
 
album = open(failinimi, encoding = "UTF-8")

järg = 1

for lugu in album:
    album_sisu = album.readline()
    while album_sisu != "":
        järg  = 1
        print("{}. {}".format(järg, album_sisu.strip()))
        album_sisu = album.readline()
album.close

>>> %Run ut.py
Sisesta failinimi: s
1. Galantis - Louder, Harder, Better

CodePudding user response：

You are already iterating over the file line, by line, but then you also execute album.readline() which will throw away the previous line. No need for that:

with open(failinimi, encoding = "UTF-8") as album:

    järg = 1

    for lugu in album:
        if lugu != "":
            järg  = 1
            print("{}. {}".format(järg, lugu.strip()))

No need to close the file if you can use with open(...

Also you can simplify the processing of the filename:

failinimi = input("Sisesta failinimi: ")
 
if failinimi in ["jukebox.txt", "80ndad.txt", "eesti_muusika.txt"]:
    failinimi = "ut/"   failinimi 
else:
    failinimi = "ut/edm.txt"
