Django Python shell縮進錯誤

Question

當我將下面的代碼粘貼到我的python shell中時。我收到一個縮進錯誤。

... 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) 

我得到一個壓痕錯誤，當我從外殼，運行這是爲什麼呢？`

這是很難確定的縮進錯誤。因爲Python支持單向縮進。您可能一次使用Tab和空格。請自行檢查並一次僅使用一個。建議使用空格。
