import codecs

boy =[]
girl = []
cunoe = 1
for each_sdk in f:
    if each_sdk[:6] != "=======":
        (reo,line_spoken) = each_sdk.split(":",1)
        if reo == "小甲鱼":
            boy.append(line_spoken)
        if reo =="小客服":

    else:
        name_girl = "girl_"+ str(cunoe) + '.txt' 
        name_boy = 'boy_'+ str(cunoe) + '.txt'

        boy_file = open(name_boy,"w") 
        girl_file = open(name_girl,'w')

        boy_file.writelines(boy)
        girl_file.writelines(girl)

        boy_file.close()
        girl_file.close()

        boy= []
        girl = []
        cunoe += 1
name_girl = "girl_"+ str(cunoe) + '.txt' 
name_boy = 'boy_'+ str(cunoe) + '.txt'

boy_file = open(name_boy,"w") 
girl_file = open(name_girl,'w')

boy_file.writelines(boy)
girl_file.writelines(girl)

boy_file.close()
girl_file.close()

f.close()

我自己与视频教学中的代码检查过了没有问题但是报错，求救啊

Traceback (most recent call last):
  File "D:\File\新建文本文档.py", line 9, in <module>
    (reo,line_spoken) = each_sdk.split(":",1)
ValueError: not enough values to unpack (expected 2, got 1)

嗯，代码确实可以运行了，但是分割出来的文件内容却为空
