print“意外错误：”，键入（e），e

Question

我正在编写一个简单的python程序，连接到我的Mongo数据库，使用自定义应用程序（Oracle E-biz，SAP等除外）提取所有客户端，如下所示：

def Customers_Applications（）：

  try:
                    cursor = customers.find({},{"_id":1,"Applications":1}).sort("Applications",pymongo.DESCENDING)
                    counter = 0
                    Total  = customers.count()
                    for doc in cursor:
                            for app in doc['Applications']:
                                    if app not in ["Oracle E-Biz", "SAP", "PeopleSoft"]:
                                            print "Customer Name: %s \t Application Name: %s" % (doc['_id'],'' .join(app))
                                            #print "Customer Name: %s \t Application Name: %s" % (doc['_id'],' ' .join(doc['Applications']))
                                            counter += 1
                    print "\n"
                    print "Total %s Customers : %s (%s%%)" %(x,counter, counter*100/Total)
 except Exception as e:
                    print "Unexpected error:", type(e), e

打印输出时，根据第一个字段的值显示第二个字段输出未对齐，如下所示：

Customer Name: Zinga   Application Name: Trizetto
Customer Name: Bongo   Application Name: Trizetto
Customer Name: Bank of Jamunda     Application Name: Actimiz
Customer Name: Bank of Tongo   Application Name: TouchPoint
Customer Name: Copa    Application Name: Sharepoint
Customer Name: US-Copa     Application Name: SharePoint
Customer Name: Camba   Application Name: Kronos

我正在使用＆＃34; \ t＆＃34;两个字段之间的选项，但它在打印时没有帮助对齐。我是这个世界的新手，我很确定会犯一些新手的错误。

感谢Python大师的指导。感谢您的时间和关注。

Answer 1

\t - 通常被视为4个空格，你可以使用.format来获得这个空间

 print "{0} {1} {2} {3}"
   .format("Customer Name: ", doc['_id'], 'Application Name: ', 'data'))

=================================== def Customers_Applications（）：

  try:
                    cursor = customers.find({},{"_id":1,"Applications":1}).sort("Applications",pymongo.DESCENDING)
                    counter = 0
                    Total  = customers.count()
                    for doc in cursor:

                                            counter += 1
                    print "\n"
                    print "Total %s Customers : %s (%s%%)" %(x,counter, counter*100/Total)
 except Exception as e:
