def shorten_filename(filename, limit=100):
    """返回合适长度文件名，中间用...显示"""
    if len(filename) <= limit:
        return filename
    else:
        return filename[:int(limit / 2) - 3] + '...' + filename[len(filename) - int(limit / 2):]


filename = '{}.txt'.format('Lorem ipsum dolor sit amet, consectetur adipiscing elit' * 30)
print(filename)
print(shorten_filename(filename))
