我想提取文本文件的某些部分。我的輸入文件:如何從文件中提取某些文本?
-- num cell port function safe [ccell disval rslt]
"17 (BC_1, CLK, input, X)," &
"16 (BC_1, OC_NEG, input, X), " &-- Merged input/
" 8 (BC_1, D(8), input, X)," & -- cell 16 @ 1 -> Hi-Z
" 7 (BC_1, Q(1), output3, X, 16, 1, Z)," &
" 0 (BC_1, Q(8), output3, X, 16, 1, Z)";
,我需要的輸出是這樣:
num cell port function safe ccell
17 BC_1 CLK input X
16 BC_1 OC_NEG input X
16 BC_1 * control 1
8 BC_1 D8 input X
7 BC_1 Q1 output3 X 16 1
0 BC_1 Q8 output3 X 16 1
到目前爲止,我嘗試下面的代碼,但它給了指數的錯誤。請建議。
import re
lines=open("input.txt",'r').readlines()
for line in lines:
a=re.findall(r'\w+',line)
print re.findall(r'\w+',line)
print a[0],a[1],a[2],a[3],a[4],a[5],a[6]
我使用的Python 2.6.6和錯誤如下:
['num', 'cell', 'port', 'function', 'safe', 'ccell', 'disval', 'rslt']
num cell port function safe ccell disval
['17', 'BC_1', 'CLK', 'input', 'X']
17 BC_1 CLK input X
Traceback (most recent call last):
File "C:\Users\ctee1\Desktop\pyparsing\outputparser.py", line 39, in <module>
print a[0],a[1],a[2],a[3],a[4],a[5],a[6]
IndexError: list index out of range
什麼語言是這個呢?我們能否得到確切的異常信息的副本? – Dessus 2012-01-05 03:54:15
可能是python? – 2012-01-05 04:00:38
