我正在尝试读取一个看起来像这样的文件:
Protein in water

300LEU O 2953 7.955 15.799 13.093 -0.2261 -0.5800 0.0226
我必须去掉前两行并分别阅读不同的列。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)
但我收到以下错误:
300LEU H 2946 8.110 15.548 13.027 -0.0632 0.8718 -0.8443
Traceback (most recent call last):
File "rmsd_cg_vs_aa.py", line 50, in <module>
col1,col2,col3,col4,col5,col6,col7,col8,col9 = line_aa.split('\t',9)
ValueError: need more than 1 value to unpack
我在这里想念什么?
