如何分割python中每个新行上的文件

Question

我有一个txt文件，我想在新行的基础上分割它。我编写代码，然后找出错误，并帮助我。代码是

 file = open("C:/Python26/trigram.txt");
 f = open("Prefix.txt",'w');
 f_up = open("Prefix.txt",'w');
 contents=file.read();
 tokens = nltk.word_tokenize(contents);
 for t in tokens:
     print t

我的文件看起来如下：

IL-2$gene$expression$and
IL-2$gene$expression$and$NF-kappa
IL-2$gene$expression$and$NF-kappa$B
IL-2$gene$expression$and$NF-kappa$B$activation
gene$expression$and$NF-kappa$B$activation$through
expression$and$NF-kappa$B$activation$through$CD28

就像这样：

with open("C:/Python26/trigram.txt") as f:
    my_list = f.readlines()
    for x in my_list:
        print x

或

with open("C:/Python26/trigram.txt") as f:
    for lines in f:
        print lines
