重复写入stdin并从python中读取进程的stdout

import subprocess

def communicate_with_process(input_data):
    # 创建子进程并建立通信管道
    process = subprocess.Popen(['python', 'your_script.py'], 
                               stdin=subprocess.PIPE, 
                               stdout=subprocess.PIPE,
                               universal_newlines=True)

    # 向子进程写入数据
    process.stdin.write(input_data)
    process.stdin.flush()

    # 从子进程读取输出
    output = process.stdout.read()

    # 关闭管道和子进程
    process.stdin.close()
    process.stdout.close()
    process.wait()

    return output

# 调用函数并传入输入数据
input_data = "Hello, subprocess!"
output = communicate_with_process(input_data)

print(output)
