删除重复行 - 除了它包含了一个“{”或“}”

我有喜欢的内容非常大的文本文件：删除重复行 - 除了它包含了一个“{”或“}”

@INBOOK{Ackermann1999-b, 
    author = {Ackermann, K.-F. and Ackermann, K.-F. and Ackermann, K.-F. and Ackermann, 
     K.-F. and Ackermann, K.-F. and Ackermann, K.-F. and Ackermann, K.-F. 
     and Ackermann, K.-F. and Ackermann, K.-F. and Ackermann, K.-F. and 
     Ackermann, K.-F. and Ackermann, K.-F. and Ackermann, K.-F. and Ackermann, 
     K.-F. and Ackermann, K.-F. and Ackermann, K.-F. and Ackermann, K.-F. 
     and Ackermann, K.-F. and Ackermann, K.-F. and Ackermann, K.-F. and 
     Ackermann, K.-F. and Ackermann, K.-F. and Ackermann, K.-F. and Ackermann, 
     K.-F. and Ackermann, K.-F. and Ackermann, K.-F. and Ackermann, K.-F. 
     and Ackermann, K.-F. and Ackermann, K.-F. and Ackermann, K.-F. and 
     Ackermann, K.-F. and Ackermann, K.-F. and Ackermann, K.-F. and Ackermann}, 
    year = {1980}, 
    timestamp = {1995-12-02} 
}

，我想删除除包含这些行重复的行括号{或}。结果应该是这样的：

@INBOOK{Ackermann1999-b, 
    author = {Ackermann, K.-F. and Ackermann, K.-F. and Ackermann, K.-F. and Ackermann, 
     Ackermann, K.-F. and Ackermann, K.-F. and Ackermann, K.-F. and Ackermann}, 
    year = {1980}, 
    timestamp = {1995-12-02} 
}

我用这个Python的Skript碰到过，由于维奈Sajip：

lines_seen = set() # holds lines already seen 
outfile = open("literatur_clean.txt", "w") 
for line in open("literatur_dupl.txt", "r"): 
    if line not in lines_seen: # not a duplicate 
     outfile.write(line) 
     lines_seen.add(line) 
outfile.close()

但它也删除了与一个右括号行}，并与线相同的authordata。为此，我需要括号的条件。

有人可以指出我添加此条件吗？

由于提前，

if ('{' in line or '}' in line) and line not in lines_seen: # not a duplicate

感谢eumiro，用小修饰“或”，而不是“和”它完美：如果（“{”在线或“}”在线）或线不在line_seen： – StandardNerd
