這是我的代碼：bookings = ['blue,red', 'green,orange', 'yellow, purple']number = 0b = 0c = 1file_test = open('test_1.txt' , 'wt')results_song = []for item in bookings:   words = bookings[number].split(',')   results_song.append(words[0])   results_song.append(words[1])   number = number + 1results_song_str = '\n'.join(results_song)print(results_song_str)file_test.write(results_song_str)file_test.close()file_test = open('test_1.txt' , 'r')line = file_test.readlines()for item in bookings:    line_1 = line[b]    line_2 = line[c]    answer = input('If first word is then what is the second word')    if answer == line_2:       print('correct')    else:       print('wrong')    b = b + 2    c = c + 2但是，代碼不會識別答案等于line_2。我無法弄清楚為什么會這樣。我已經(jīng)檢查過這c是正確的數(shù)字，并且line_2與答案相同。但我確實(shí)注意到，當(dāng)我在打印答案時運(yùn)行代碼并且line_2這會返回：redred但我從來沒有在這里添加新的線路功能。任何幫助將不勝感激，因?yàn)槲倚枰獙⒋舜a用于學(xué)校作業(yè)。
