这个错误可能是因为在读取txt文件时，没有找到相应的文件导致的。建议在读取txt文件之前，先添加一个判断文件是否存在的语句。例如：
 程序代码：if not os.path.exists(src_txt): print("No txt_file exist!") exit() 同时，也建议在读取txt文件时，使用strip()方法去除每行末尾的空格和换行符，例如： 程序代码：for line in f.readlines(): line = line.strip() each_of_time_duration=(len(line)-1)/(180/60) ... # 省略内容 |

print(src_path)

print(src_path)

for item in src_path.iterdir():
if ".mp4" in str(item):
mp4_list.append(str(item))
elif ".txt" in str(item):

print(mp4_list)

if len(mp4_list)>0:
src_mp4=random.choice(mp4_list) #随机选取一个音频文件并得到相应的txt文件
src_txt=src_mp4.replace("mp4","txt")

exit()

运行后，到最后这一步出错：TypeError: cannot unpack non-iterable NoneType object
