Python 2.7 Appengine中的日志记录失败

我正在尝试在应用商店1.9.26和Python2.7.9中导入DB，为此，我想做一些日志记录，以便检查一些变量并了解发生了什么情况

import logging

[...]    

updateDueDate = '2016.3.15'
fmt ='%Y.%m.%d'
fechalinea = datetime.datetime.strptime(updateDueDate,fmt)
fecha_aviso = avisoDB.modificacion.due_date.strftime(fmt)
logging.error = ('Date Call= %s, Date DB= %s' %(fecha_aviso, fechalinea))

这应该很简单，但它不起作用。我想我搞砸了我的python安装或与我的代码无关的东西，因为我从devserver获得的输出是：

TypeError("'str' object is not callable",)
TypeError("'str' object is not callable",)

尝试升级python和GAE launcher，google解决了这个问题，但是由于所有不同的选项，我得到了相同的错误，我很确定这与我的代码无关，但是。。。有人知道发生了什么事吗

感谢

logging.error=

将模块

logging

的属性

error

指定为右侧（在您的示例中为字符串），替换其先前的值（这是一个函数）

当任何Python代码（您的或SDK中的）稍后调用

logging.error

（您已将其设置为字符串）时，它当然会产生

TypeError（“'str'对象不可调用”）

我想我把python安装搞砸了

是的，通过将字符串分配给

日志记录。错误

或者与我的代码无关的东西

这一切都与你的代码有关——是你的代码做了错误的赋值

需要睡一觉……读同一个错误已经三个多小时了，却没有注意到“=”符号。无论如何thanks@unaiherran，发生在我们所有人身上，尤其是当我们睡眠不足时（总是一种诱惑！）。去休息吧，永远乐意帮忙！
