需要一种更好的方法从python执行控制台命令并记录结果

import subprocess

# 执行命令并记录结果
result = subprocess.run(["ls", "-l"], stdout=subprocess.PIPE, stderr=subprocess.PIPE, text=True)

# 打印命令执行结果
print("返回代码：", result.returncode)
print("输出：", result.stdout)
print("错误：", result.stderr)

import subprocess

# 创建一个Popen对象并传递命令
process = subprocess.Popen(["ls", "-l"], stdout=subprocess.PIPE, stderr=subprocess.PIPE, text=True)

# 使用循环实时流式传输输出
while True:
    output = process.stdout.readline()
    if output == '' and process.poll() is not None:
        break
    if output:
        print(output.strip())

# 获取返回代码
return_code = process.poll()
print("返回代码：", return_code)
