Python script gets the operating system version information _python

Viewing system version information is a commonplace thing, sometimes need to input version information into the asset management system, if each manual to query the information and input system is a headache, if the script to complete this matter, then the situation is different.

In the Python world, getting Windows version information and Linux version information can take the platform module, but the platform module is not omnipotent, some special information (such as Windows version number) This module is not available, Then there's only a choice.

In a Linux system, you can simply think of everything as a file, so you can use the open () file to control the file's reading and writing, even if no ready-made commands are available. Most of the information in Windows can be found in the registry, so you can start from the registry. Windows registry is a good thing, take the data just like in Linux everything is as convenient as files, if you want to access the registry with Python, in addition to the permissions is required module, in Python _winreg is a built-in module, through this module can read and write to the registry.

This script collects some common ways to get version information, in addition to the Platform module, there are other modules available because the Platform module is not a built-in module and therefore requires additional installation. Running a script under Windows requires permission issues and Chinese character issues, and the problem with writing in Python printing is done through the get_system_encoding () function in the script, which is taken from Django, and is very useful for testing this function.

Note: In the pycharm, often encountered in the run window printed in Chinese display garbled, the code does not pass the correct transcoding is on the one hand, and the IDE's coding settings is also an aspect. If you are developing under Windows, then the recommended code is written in UTF-8, the IDE's encoding is set to "GBK", set method "file"--> "Settings"--> "Editor"--> "File Encoding"- > IDE Encoding Select <system Default (now GBK) >, Project Encoding choose UTF-8 to guarantee code consistency.

The

script is as follows:
