Python
我想对文本进行pos-tag
import nltk;
file_object = open('E:\\practise\\Web1T5-Easy-1.1\\3grams\\3gm-0000.txt')
try:
for eachline in file_object:
print eachline,;
text = nltk.word_tokenize(eachline)
nltk.pos_tag(text)
finally:
file_object.close( )
但是结果显示
> "D:\software\python\Python27\python.exe" -u "E:\practise\python\postagger_test.py"
! " '' 508
Traceback (most recent call last):

我想问一下有什么问题吗？那位大神告诉我一下可以把pos-tag完了之后的结果输出到另一个文本。谢谢
