我在读一个文件，它看起来像：Protein in water

我得把前两行去掉，分别读不同的专栏。

我试过这个：with open('file.txt') as fa:

for line_aa in fa.readlines()[3:11]:

line_aa = line_aa.strip()

print line_aa

col1,col2,col3,col4,col5,col6,col7,col8,col9 = line_aa.split('\t',9)

但我得到了以下错误：300LEU H 2946 8.110 15.548 13.027 -0.0632 0.8718 -0.8443

Traceback (most recent call last):

col1,col2,col3,col4,col5,col6,col7,col8,col9 = line_aa.split('\t',9)

ValueError: need more than 1 value to unpack

我错过了什么？
