python运行不了、显示警告_Python xlrd:禁止显示警告消息
查看xlrd docs的相关部分。open_workbook函数的第二个参数是logfile，它应该是一个打开的文件对象或类似的操作。它只需要支持一个write方法。它默认为sys.stdout。
所以，像这样的东西（未经测试）应该可以完成这项工作：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
更新以回应@DaniloBargen的回答：
单独编写换行符的不是xlrd，而是Pythonprint语句/函数。此脚本：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Python2.2到2.7（包括2.2和2.7）生成此输出：'foo'
'\n'
'bar'
'\n'
'baz'
'\n'
适当的现代化脚本（作为函数而不是语句打印）为2.6、2.7、3.1、3.2和3.3生成相同的输出。你可以用一个更复杂的过滤器类来解决这个问题。以下示例还允许检查短语序列：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()
