如何从python脚本向命令行发送数据

import subprocess

def send_data_to_command_line(data):
    command = "command_line_command"  # 替换为实际的命令行命令
    process = subprocess.Popen(command, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True)
    stdout, stderr = process.communicate(input=data.encode())  # 将数据编码后传递给命令行
    return stdout.decode(), stderr.decode()

data = "要发送的数据"
result = send_data_to_command_line(data)
print(result)

import os

def send_data_to_command_line(data):
    command = "command_line_command"  # 替换为实际的命令行命令
    process = os.popen(command, 'w')
    process.write(data)
    process.close()

data = "要发送的数据"
send_data_to_command_line(data)

import sys

def send_data_to_command_line(data):
    sys.stdout.write(data)
    sys.stdout.flush()

data = "要发送的数据"
send_data_to_command_line(data)
