在Python多线程应用程序中将变量设置为无
我有一个Python多线程的小应用程序,最近给我带来了如下错误:在Python多线程应用程序中将变量设置为无,python,multithreading,Python,Multithreading,我有一个Python多线程的小应用程序,最近给我带来了如下错误: Exception in thread Thread-2: Traceback (most recent call last): File "/usr/local/Cellar/python/2.7.12_2/Frameworks/Python.framework/Versions/2.7/lib/python2.7/threading.py", line 801, in __bootstrap_inner self.

在父线程中设置
是启动线程的代码
此应用程序运行了一段时间,然后突然以这种方式失败
在当前失败的同一个方法中,我最初得到错误NoneType对象没有属性debug
,因为我在父线程中创建的记录器实例上调用了logger.debug(…)
。我用以下代码修复了这个问题,但现在怀疑我是在修复症状,而不是问题:
try:
logger
except NameError:
logger = None
finally:
if logger == None:
import logging
logger = logging.getLogger('Twitter Enrichment')
我遗漏的根本问题是什么 您能否显示启动流程的代码?已更新。另外,还有一个更新:它总是在崩溃前保存9个用户的数据。总是9点。
