我目前正在尝试从我读过的文件中提取数据：
with open(_args.file, 'ru') as _fpInput:
# Remove empty lines
lines = [l for l in _fpInput if(l[:-1])]
# Process special characters
clean = ''.join(lines)
clean = ''.join(clean.split('\x08')) # Remove Backspace
clean = ''.join(clean.split('\x1b')) # Remove Escape
clean = ''.join(clean.split('\r')) # Remove Carriage Return
# Remove space bar print, to print, another page
_lines = re.sub('\[7m--More--\[27m', '', clean)
然后我执行find all：
chunk = ''.join(re.findall('show[a-z \t\b]*[ \t\b][a-z \t\b]*cell[a-z \t\b]*[ \t][a-z \t\b]*umts\s+(.*?)\[ok\]', lines, re.DOTALL|re.I)).split('\n')
还有：
chunk = ''.join(re.findall('show[a-z \t\b]*[ \t\b][a-z \t\b]*cell[a-z \t\b]*[ \t][a-z \t\b]*lte\s+(.*?)\[ok\]', lines, re.DOTALL|re.I)).split('\n')
当我浏览文件1时，所有工作都按预期工作，但在文件2中它只是不起作用。

以下是我将如何解析文件。 parse（）返回已解析表的列表 - 每个表都是一个字典列表，每个字典代表文件中的一行。
import re
def parse(rows):
tables = []
while True:
r = next(rows, None)
if r is None: break
# find the header line
if r.startswith("CellHandle Name "):
next(rows)
headers = r.split()
table = []
while True:
r = next(rows, None)
if r is None: break
vals = r.split()
# skip blank lines or the lines with dashes
if len(vals) == 0 or re.match("\A-+\Z", vals[0]): continue
# stop if first column is not a number
if not re.match("\A\d+\Z", vals[0]): break
item = dict(zip(headers, vals))
table.append(item)
tables.append(table)
return tables
def test(path):
print "for file", path
with open(path, 'r') as h:
tables = parse(h)
print " - tables found:", len(tables)
for i,t in enumerate(tables):
print " * rows in table ", (i+1), ":", len(t)
for item in t: print item
test("file1")
