如何在Python中找到当前的操作系统？

import os

print(os.name)  # 返回：posix
print(os.getpid())  # 返回：PID
print(os.system('uname -a'))  # 执行uname命令获取系统信息

import platform

print(platform.platform())  # 返回：Windows-11-9.6.18-10.0.20322.860, Intel64 Family 6 Model 35 Stepping 0, GenuineIntel
print(platform.release())  # 返回：20.30.3(P37251,402237311)

import sys

print(sys.platform)  # 返回：darwin
print(sys.implementation)  # 返回：CPython

import os
cmd = "uname -a"
result = os.popen(cmd).read().strip()
print(result)  # 获取当前系统信息
