在Python中运行外部程序(可执行文件)？

import subprocess

# 运行外部程序并等待它完成
result = subprocess.run(["ls", "-l"], stdout=subprocess.PIPE, stderr=subprocess.PIPE, text=True)

# 输出结果
print("返回代码：", result.returncode)
print("标准输出：", result.stdout)
print("标准错误：", result.stderr)

import subprocess

# 运行外部程序并等待它完成
process = subprocess.Popen(["ping", "www.google.com"], stdout=subprocess.PIPE, stderr=subprocess.PIPE, text=True)

# 实时读取输出
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
print("返回代码：", process.returncode)
