[已解决]课后作业31讲：用pickle将文件里的对话按照以下要求腌制成不同文件

森亦简

按照课上的代码，不知道为啥会报错，求解惑
报错内容：

Traceback (most recent call last):
  File "C:/Users/wxl0311/Desktop/新建文件夹/221.py", line 22, in <module>
    (role,line_spoken) = each_line.split(":",1)
ValueError: not enough values to unpack (expected 2, got 1)

Traceback (most recent call last):
  File "C:/Users/wxl0311/Desktop/新建文件夹/221.py", line 22, in <module>
    (role,line_spoken) = each_line.split(sep=":",maxsplit=1)
ValueError: not enough values to unpack (expected 2, got 1)

我的代码：报错在第22行

1. def save_file(boy,girl,count):
   
2.     import pickle
   
3.     boy_file_name = "boy_" + str(count) + ".txt"
   
4.     girl_file_name = "girl_" + str(count) + ".txt"
   
5.    
   
6.     boy_file = open(boy_file_name,"wb")
   
7.     girl_file = open(girl_file_name,"wb")
   
8.    
   
9.     pickle.dump(boy,boy_file)
   
10.     pickle.dump(girl,girl_file)
    
11.    
    
12.     boy_file.close()
    
13.     girl_file.close()
    
14.    
    
15. f = open("record.txt")
    
16. count = 1
    
17. boy = []
    
18. girl = []
    
19. 
    
20. for each_line in f:
    
21.     if each_line[:6] != "=====":
    
22.         (role,line_spoken) = each_line.split(":",1)
    
23.         if role == "小甲鱼":
    
24.             boy.append(line_spoken)
    
25.         if role == "小客服":
    
26.             girl.append(line_spoken)
    
27.     else:
    
28.         save_file(boy,girl,count)
    
29. 
    
30.         count = 1
    
31.         boy = []
    
32.         girl = []
    
33.         
    
34. save_file(boy,girl,count)
    
35. f.close()

if each_line[:6] != "=====": 这行代码 等号少一个，导致 if 必成立

而当全是等号那行文本时，没有冒号 split 切割只会返回一个元素，但你需要赋值给两个变量而报错

1. def save_file(boy,girl,count):
   
2.     import pickle
   
3.     boy_file_name = "boy_" + str(count) + ".txt"
   
4.     girl_file_name = "girl_" + str(count) + ".txt"
   
5.    
   
6.     boy_file = open(boy_file_name,"wb")
   
7.     girl_file = open(girl_file_name,"wb")
   
8.    
   
9.     pickle.dump(boy,boy_file)
   
10.     pickle.dump(girl,girl_file)
    
11.    
    
12.     boy_file.close()
    
13.     girl_file.close()
    
14.    
    
15. f = open("record.txt")
    
16. count = 1
    
17. boy = []
    
18. girl = []
    
19.

21.     if each_line[:6] != "======":
    
22.         (role,line_spoken) = each_line.split(":",1)
