查看xlrd文档的相关部分。open_workbook函数的第二个arglogfile应该是一个打开的文件对象或类似行为。它所需要支持的只是一种write方法。默认为sys.stdout。
因此，应执行以下操作（未测试）：
class MyFilter(object):
def __init__(self, mylogfile=sys.stdout):
self.f = mylogfile
def write(self, data):
if "WARNING *** OLE2 inconsistency" not in data:
self.f.write(data)
#start up
log = open("the_log_file.txt", "w")
log_filter = MyFilter(log)
book = xlrd.open_workbook("foo.xls", logfile=log_filter)
# shut down
log.close()
# or use a "with" statement
以回复@DaniloBargen的回答：
不是xlrd单独编写换行符，而是Pythonprint语句/函数。该脚本：
class FakeFile(object):
def write(self, data):
print repr(data)
ff = FakeFile()
for x in "foo bar baz".split():
print >> ff, x
为所有Python 2.2至2.7（包括以下两个）生成此输出：
'foo'
'\n'
'bar'
'\n'
'baz'
'\n'
适当现代化的脚本（作为功能而不是语句打印）对于2.6、2.7、3.1、3.2和3.3产生相同的输出。您可以使用更复杂的过滤器类来解决此问题。以下示例另外允许检查短语序列：
import sys, glob, xlrd
class MyFilter(object):
def __init__(self, mylogfile=sys.stdout, skip_list=()):
self.f = mylogfile
self.state = 0
self.skip_list = skip_list
def write(self, data):
if self.state == 0:
found = any(x in data for x in self.skip_list)
if not found:
self.f.write(data)
return
if data[-1] != '\n':
self.state = 1
else:
if data != '\n':
self.f.write(data)
self.state = 0
logf = open("the_log_file.txt", "w")
skip_these = (
"WARNING *** OLE2 inconsistency",
)
try:
log_filter = MyFilter(logf, skip_these)
for fname in glob.glob(sys.argv[1]):
logf.write("=== %s ===\n" % fname)
book = xlrd.open_workbook(fname, logfile=log_filter)
finally:
logf.close()
