My friend wanted me to send her a list of songs from one of my iTunes playlists, so I exported the playlist within the app itself.  It comes as a plain text file, where each field is separated a '\t' and each line is separated by a '\r'. Since there is so much extraneous information, I decided to write a Python script that would delete all fields but the song title and artist name. How is the design and format of my code? How does it fit in with Python best practices? Is there a much easier way to do accomplish the same job that I just overlooked?The input file looks like:Name\tArtist\tComposer\tAlbum\tGrouping\tGenre\tSize\tTime\tDisc Number\tDisc Count\tTrack Number\tTrack Count\tYear\tDate Modified\tDate Added\tBit Rate\tSample Rate\tVolume Adjustment\tKind\tEqualizer\tComments\tPlays\tLast Played\tSkips\tLast Skipped\tMy Rating\tLocationYou Shook Me All Night Long\tAC/DC\t\tThe Very Best\t\tHard Rock\t5468228\t212\t\t\t9\t\t2001\t4/17/12, 2:29 PM\t4/17/12, 2:26 PM\t192\t44100\t\tMPEG audio file\t\t\t5\t3/12/13, 10:41 PM\t\t\t\tMacintosh HD:Users:UserName:Music:iTunes:iTunes Media:Music:AC_DC:The Very Best:09 You Shook Me All Night Long.mp3The output file looks like:Name\tArtist\tYou Shook Me All Night Long\tAC/DC\tMiss Murder\tAFI\tMy code is:from sys import argvdef main(file):    with open(argv[1], 'r') as file:        data = file.read()        newdata = data.split('\r')        output = []        for line in newdata:            tabc = 0            newline =             for char in line:                newline += char                if char == '\t':                    tabc += 1                    if tabc == 2: break            output.append(newline)        outPutString = '\n'.join(output)    with open(argv[1][:-4]+'Out.txt', 'w') as file:        file.write(outPutString)if __name__ == '__main__':    file = argv[1]    main(file)
