如何在python的每一個新行上拆分文件

Question

我有一個txt文件，我想在新行的基礎上拆分它。我寫代碼，然後找到它的錯誤，並幫助我。代碼是

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 

我的文件看起來像這樣：

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

嘗試這樣的：

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

OR

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