text_generator.py“访问被拒绝”

Question

此代码有问题。出于某种原因，每当我使用测试客户端时，都会收到此消息。

import stdio
import sys
from markov_model import MarkovModel


def main():
    k = int(sys.argv[1])
    T = int(sys.argv[2])
    # text from standard input initialized to variable
    text = sys.stdin.read()
    # slices text and initializes it to kgram
    kgram = text[:k]
    model = markov_model(text, k)
    # model is used to generate random length of text
    stdio.writeln(model.gen(kgram, T))


if __name__ == '__main__':
    main()
