如何在Python中修复'NameError'

Question

我有一些代码。当用户在输入行中输入“日期”时，输出必须是日期，例如2019-06-8 16:34:40 但是程序找不到输入文本-未定义名称“日期”

import datetime

x = input("Type your question here ... ")
########## Date ##########
now = datetime.datetime.now()
date = "Date"
if x == date:
  print "Current date and time:"
  print str(now)

########## (Can't find anything) ##########
else:
  print("Something goes wrong ;( ")

错误- NameError：名称“日期”未定义

在Python 3中

import datetime

x = input("Type your question here ... ")
########## Date ##########
now = datetime.datetime.now()
date = "Date"
if x == date:
  print ("Current date and time:")
  print (str(now))

########## (Can't find anything) ##########
else:
  print("Something goes wrong ;( ")

，输出为：

Type your question here ... Date                                                                                                                              
Current date and time:
