当我将下面的代码粘贴到我的python shell中时。我收到一个缩进错误。

... print "this is an ideal answer for both" File "", line 2 print "this is an ideal answer for both" ^IndentationError: expected an indented block

def get_match(user_a, user_b): 
    user_a_answers = UserAnswer.objects.filter(user=user_a)[0] 
    user_b_answers = UserAnswer.objects.filter(user=user_b)[0] 
    if user_a_answers.question.id == user_b_answers.question.id: 
     user_a_answer = user_a_answers.my_answer 
     user_a_pref = user_a_answers.their_answer 
     user_b_answer = user_b_answers.my_answer 
     user_b_pref = user_b_answers.their_answer 
     if user_a_answer == user_b_pref: 
      print "%s fits with %s's preference" %(user_a_answers.user.username, user_b_answers.user.username) 
     if user_a_pref == user_b_answer: 
      print "%s fits with %s's preference" %(user_a_answers.user.username, user_b_answers.user.username) 
     if user_a_answer == user_b_pref and user_a_pref == user_b_answer: 
      print "this is an ideal answer for both" 




get_match(mohit, saraswati) 
get_match(saraswati, userc) 
get_match(mohit, userc)

这是很难确定的缩进错误。因为Python支持单向缩进。您可能一次使用Tab和空格。请自行检查并一次仅使用一个。建议使用空格。
