如果要自己解析，可以使用split标记用户输入，并基于标记执行命令，如下所示:

If you want to parse by yourself, you can use split to tokenize the user input, and execute your commands based on the tokens, sort of like this:

try:
    while True:
        input = raw_input('> ')
        tokens = input.split()
        command = tokens[0]
        args = tokens[1:]
        if command == 'init':
            # perform init command
        elif command == 'blah':
            # perform other command


except KeyboardInterrupt:
    pass
