Question

f = open('E:\\11.11.txt')

boy = []
girl = []
count = 1

for each_line in f:
    if each_line in f[: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:
        #文件分别保存操作#
        file_name_boy = 'boy_' + str(count) + '.txt'
        file_name_girl = 'boy_' + str(count) + '.txt'

        boy_file = open(file_name_boy,'w')
        girl_file = open(file_name_girl,'w')

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

        boy_file.close()
        girl_file.close()

        boy = []
        girl = []
        count += 1

f.close()
