[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

def save_file(boy,girl,count):
    import pickle
    boy_file_name = "boy_" + str(count) + ".txt"
    girl_file_name = "girl_" + str(count) + ".txt"
    
    boy_file = open(boy_file_name,"wb")
    girl_file = open(girl_file_name,"wb")
    
    pickle.dump(boy,boy_file)
    pickle.dump(girl,girl_file)
    
    boy_file.close()
    girl_file.close()
    
f = open("record.txt")
count = 1
boy = []
girl = []

for each_line in f:
    if each_line[:6] != "=====":
        (role,line_spoken) = each_line.split(":",1)
        if role == "小甲鱼":
            boy.append(line_spoken)
        if role == "小客服":
            girl.append(line_spoken)
    else:
        save_file(boy,girl,count)

        count = 1
        boy = []
        girl = []
        
save_file(boy,girl,count)
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

def save_file(boy,girl,count):
    import pickle
    boy_file_name = "boy_" + str(count) + ".txt"
    girl_file_name = "girl_" + str(count) + ".txt"
    
    boy_file = open(boy_file_name,"wb")
    girl_file = open(girl_file_name,"wb")
    
    pickle.dump(boy,boy_file)
    pickle.dump(girl,girl_file)
    
    boy_file.close()
    girl_file.close()
    
f = open("record.txt")
count = 1
boy = []
girl = []

for each_line in f:
    if each_line[:6] != "======":
        (role,line_spoken) = each_line.split(":",1)
        if role == "小甲鱼":
            boy.append(line_spoken)
        if role == "小客服":
            girl.append(line_spoken)
    else:
        save_file(boy,girl,count)

        count = 1
        boy = []
        girl = []
        
save_file(boy,girl,count)
f.close()
