Appengine中的日誌記錄失敗

Question

我試圖做一些導入到應用程序商店1.9.26，在蟒蛇2.7.9，一個數據庫併爲此，我想獲得一些日誌，所以我可以檢查一些變量和看看正在發生的事情

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)) 

這應該是非常簡單的，但它不工作。我想我搞砸了我的Python安裝目錄表或者一些有關無關我的代碼，因爲輸出我從devserver得到的是：

嘗試升級Python和GAE發射器，谷歌的這個問題，但所有不同的選項我都會得到相同的錯誤，而且我很確定它與我的代碼無關，但是......任何人都對發生的事情有任何想法？

由於

Answer 1

logging.error =分配右手側（在您的情況下，字符串）屬性模塊logging的error，取代它的先前值（這是一個功能）。

當任何Python代碼（你或SDK）後調用logging.error（你已經設置爲一個字符串），當然會產生TypeError("'str' object is not callable",)！

我想我搞砸了我的Python安裝目錄

是的，你做到了，通過分配一個字符串logging.error。

或東西，有沒有關係我的代碼

它具有一切與你的代碼 - 這是你的代碼，不會錯誤地分配！
