if else语句中的语法错误

Question

我一直在为这组代码中的最后一个获取语法错误，我不知道为什么。它不是一个错误的间隔它的语法所以我不明白我做错了什么。我想知道是否有人可以提供帮助。代码如下。

if pcolor == winner:
        print ('Correct!')

        while player == correct:
            phl = input('Higher or lower?').strip().lower()
            randcard = computer_pick_card()
            if randcard == 'A':
                player = correct
                print ('The card was an Ace')
                print ('Correct!')

            else:   
                if last_card != ():
                    if phl == higher:
                        if randcard >= last_card:
                            player = correct
                            print ('The card was ', randcard)
                            print ('Correct!')

                        elif randcard < last_card:
                            player != correct
                            print ('The card was ', randcard)
                            print ('You lose')
                    elif phl == lower:
                        if randcard >= last_card:
                            player != correct
                            print ('The card was ', randcard)
                            print ('You lose')

                        elif randcard < last_card:
                            player == correct
                            print ('The card was ', randcard)
                            print ('Correct!')

                else:
                    if phl == higher:
                        if randcard >= card2:
                            player = correct
                            print ('The card was ', randcard)
                            print ('Correct!')

                        elif randcard < card2:
                            player != correct
                            print ('The card was ', randcard)
                            print ('You lose')
                    elif phl == lower:
                        if randcard > card2:
                            player != correct
                            print ('The card was ', randcard)
                            print ('You lose')

                        elif randcard <= card2:
                            player == correct
                            print ('The card was ', randcard)
                            print ('Correct!')

            last_card = randcard
            return last_card

    last_card = ()
    else:
        print ('You lose')

在python中间距是语法。

你没有正确的间距。

if ...
    ...
    last_card = ()
    else:
        ...

应该是

if ...
    ...
    last_card = ()
else:
    ...
