Python子进程输出重定向

import subprocess

# 使用 subprocess.run() 运行子进程并捕获输出
result = subprocess.run(["echo", "Hello, World!"], capture_output=True, text=True)

# 打印子进程返回的状态码，标准输出和标准错误
print("Return Code:", result.returncode)
print("Standard Output:", result.stdout)
print("Standard Error:", result.stderr)

import subprocess

# 使用 subprocess.PIPE 捕获输出
result = subprocess.run(["echo", "Hello, World!"], stdout=subprocess.PIPE, stderr=subprocess.PIPE, universal_newlines=True)

# 打印子进程返回的状态码，标准输出和标准错误
print("Return Code:", result.returncode)
print("Standard Output:", result.stdout)
print("Standard Error:", result.stderr)
