Python if-else - 条件错误处理

如何解决Python if-else - 条件错误处理

• 我正在根据操作系统输出安装一些软件包。
• 我想为 linux1 和 linux2 循环引入 try-except 块（或任何更好的方法）以打印操作系统中缺少的软件包或安装时出现其他错误
• 第三个循环（Linux-Others）应该给出警告并继续安装其余的软件包，即使我有错误

import platform
operating_system=platform.platform()
def package_install():
    listA=['package1','pa9ckage2','package3']
    listB=['package4','package5','package6']
    listC=['package10','package20','package30']

    if 'linux1' in operating_system:
        self._log.info("Linux-A")
        yum_command = yum_command = [
                    YUM_EXECUTABLE,"-y","install"
                ] + listA
        return self._executor.execute_command(yum_command)
    elif 'linux2' in operating_system:
        self._log.info("Linux-B")
        yum_command = yum_command = [
                    YUM_EXECUTABLE,"install"
                ] + listB
        return self._executor.execute_command(yum_command)
    else: 
        self._log.info("Linux-Others")
        yum_command = yum_command = [
                    YUM_EXECUTABLE,"install"
                ] + listC
