输出文件调用简单的with方法处理文件

man = []        #创建列表
other = []
try:
    data = open('sketch.txt')

    for each_line in data:
        try:
            (role, line_spoken) = each_line.split(':', 1)
            line_spoken = line_spoken.strip()   #去除空白符
            if role == 'Man':
               man.append(line_spoken)      #将man的话添到man[]
               
            elif role == 'Other Man':       
               other.append(line_spoken)        #将other man的话添到列表
           
             

       
        except ValueError:      #异常处理
            pass
    if 'data' in locals():      #调用方法locals()判断‘data’文件是否存在当前环境中
        data.close()
    
except IOError:     #I/O错误处理
    print('The data file is missing!')

#将处理的数据写入man1.txt和other2.txt文档
try:
    with open('man_data.txt', 'w') as man_data:　　　　#调用with方法利用Python内置的context management protocol（上下文管理协议）自动判断文件是否关闭并处理未关闭文件
        print(man, file=man_data)
    with open('other_data.txt', 'w') as other_data:
        print(other, file=other_data)
except IOError as err:
    print('file error:' + str(err))
